How Sonar Works
Sonar technology is based on sound waves. The 300 Series??? Fishfinder uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer.
Your 300 Series??? Fishfinder sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object; it then uses the reflected signal to interpret location, size, and composition of an object.
Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that your boat can ???outrun??? this sonar signal.
SONAR is an acronym for SOund and NAvigation Ranging. Sonar uses precision sound pulses or ???pings??? which are emitted into the water in a
The sound pulses ???echo??? back from objects in the water such as the bottom, fish, and other submerged objects. The returned echoes are displayed on the LCD screen. Each time a new echo is received, the old echoes are moved across the LCD, creating a scrolling effect.
When all the echoes are viewed side by side, an easy to interpret ???graph??? of the bottom, fish, and structure appears.
The sound pulses are transmitted at various frequencies depending on the application. Very high frequencies (455 kHz) are used for greatest definition but the operating depth is limited. High frequencies (200 kHz) are commonly used on consumer sonar and provide a good balance between depth performance and resolution. Low frequencies (83 kHz) are typically used to achieve greater depth capability.
The power output is the amount of energy generated by the sonar transmitter. It is commonly measured using two methods:
???Root Mean Square (RMS) measures power output over the entire transmit cycle.
???Peak to Peak measures power output at the highest points.
The benefits of increased power output are the ability to detect smaller targets at greater distances, ability to overcome noise, better high speed performance and enhanced depth capability.
DualBeam PLUS??? Sonar
Your 300 Series??? Fishing System uses a 200/83 kHz DualBeam PLUS??? sonar system with a wide (60??) area of coverage. DualBeam PLUS??? sonar has a narrowly focused 20?? center beam, surrounded by a second beam of 60??, expanding your coverage to an area equal to your depth. In 20 feet of water, the wider beam covers an area 20 feet wide. DualBeam PLUS??? sonar returns can be blended together, viewed separately, or compared
How GPS Works
Your 300 Series??? Fishfinder also supports GPS (Global Positioning System) and chartplotting. It uses GPS and sonar to determine your position, display it on a grid, and provide detailed underwater information.
GPS uses a constellation of satellites that continually send radio signals to the earth. The GPS receiver on your boat receives signals from satellites that are visible to it. Based on time differences between each received signal, the GPS receiver determines its distance to each satellite. With distances known, the GPS receiver mathematically triangulates its own position. With once per second updates, the GPS receiver then calculates its velocity and bearing.
GPS was originally intended for military use; however, civilians may also take advantage of its highly accurate position capabilities, typically within +/- 4.5 meters, depending on conditions. This means that 95% of the time, the GPS receiver will read a location within 4.5 meters of your actual position. Your GPS Receiver also uses information from WAAS (the Wide Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are available in your area.
The following GPS functionality is currently supported by the 300 Series??? Fishfinder when it is connected to the included GPS receiver:
???View current position
???View current track (breadcrumb trail)
???View precision speed and heading from your GPS receiver
???Save tracks, waypoints, and routes
???Travel a route and navigate from one waypoint to the next.
See Chart View and Introduction to Navigation: Add Maps to Your Fishfinder for more information.
What???s on the Sonar Display
The 300 Series??? Fishfinder can display a variety of useful information about
Depth - Waterdepth; can be set to alarm when the water becomestoo shallow.
Speed - If a Temp/Speed accessory or GPS Receiver is attached, the Fishfinder can display the speed of the boat and can keep a Triplog of nautical or statutemiles traveled.
Temperature - Water surfacetemperature.
Timer - Elapsed time with Temp/Speed

Cursor Dialog Box - Indicates cursor depth on the display and the depth of the bottom directly below the cursor. The Latitude and Longitude of the cursor position, the distance to travel to the cursor position, and the bearing to the cursor position are shown with a GPS receiver. A waypoint can be marked at the cursor position for later retrieval and use with a GPS receiver.

the area under your boat, including the following items:
Bait Ball
Hollow Fish Symbol (83kHz, Wide Beam)
Fish - The Fishfinder displays fish as arches and/or fish icons, and can be set to alarm when a fish of a certain size is detected. When a target is detected, a Fish ID+??? symbol appears on the display with the depth displayed above it. The size of the symbol indicates the intensity of the sonar return. The unit will clearly show schools of Bait Fish as "clouds" of different shapes and sizes, depending on the number of fish and boat speed.
Shaded Fish Symbol (200 kHz, NarrowBeam)
Thermoclines - Layers of water with different temperatures that appear at different depths and different times of the year. A thermocline typically appears as a continuous band of gray levels moving across the display at the same depth.

Real Time Sonar (RTS???) Window
A Real Time Sonar (RTS???) Window appears on the right side of the display in the Sonar View only. The RTS Window??? updates at the fastest rate possible for depth conditions and shows only the returns from the bottom, structure, and fish that are within the transducer beam . The RTS Wind ow??? plots the depth and intensity of a sonar return (see Sonar Menu Tab: RTS Window???).
The Narrow RTS Window??? indicates the sonar intensity through the use of grayscale. The g rayscale used ma tches the Bottom View grays cale setting (Inverse, StructureID??, WhiteLine???, Bo ttom Blac k). The depth of the sonar return is indicated by t he ver tical placement of the return on the display depth scale.
The Wide R TS W indow??? indicates t he so nar i ntensity through the u se of a ba r graph. The length of the plotted r eturn indicates whether the return is weakor strong. The depth of the sonar return is in dicated by th e vertical p lacement of th e return o n the d isplay d epth

Bottom Presentation
As the boat moves, the unit charts the changes in depth on the display to create a profile of the Bottom Contour. The type of b ottom can be d etermined from the return charted on the display. A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky Bottoms have a broken, random appearance.

Inverse is a method where weak r eturns are shown with dark pixels and strong returns with lighter pixels. This has the benefit of e nsuring that weak signals will be clea rly visible on the display.
Structure ID?? represents weak returns as light pixels and strong r eturns as d ark p ixels. This ha s the benefit of ensuring that strong returns will be clearly visible on the display.
WhiteLine??? highlights the strongest sonar returns in white resulting in a dis tinctive outline. This has the benefit of clearly defining the bottom on the display.
Black (Bottom Black) displays all pixels below the bottom contour as black, regardless of signal strength. This has the benefit of pro viding a high c ontrast between the bottom and other sonar returns on the display.

Introduction to Navigation
Use your 300 Series??? Fishfinder to mark waypoints at areas of interest and to navigate to those waypoints via a savable route. A route represents the shortest intended distance between waypoints. You can a lso v iew and save tr acks, which represent the actual path of the boat.
Waypoints, Routes, and Tracks
Waypoints are stored pos itions (lat itude, lo ngitude) t hat allo w you to mar k areas of interest or navigation points (i.e. a marker buoy, dock, or fishing hole). Your Fishfinder can store up to 3000 waypoints.
Routes link two or more waypoints together to create a path for navigation and are used in trip planning. You can linkindividual waypoints together by using the GOTO key. A route represents your intended navigation and shows the shortest path from each waypoint to the next. As you travel a route, staying on the route line is the most efficient way to ge t to your dest ination, although you shoul d always l ook out for obstac les not show n on the chart. Your 300 Se ries???
Fishfinder can store up to 50 routes that can each contain up to 50 waypoints.
Tracks consist of detailed posit ion history and are displayed as a breadcrumb trail of trackpoints. The Current Track shows the position history since the unit was powered up (maximum of 20,000 trackpoints displayed). You can clear the Current Track or save it at any time. Your 300 Series???

Sensitivity
Settings: Low = 1, High = 20; Default = 10
Sensitivity controls how much detail is shown on the display and w ill adjust the sensitivity of all sonar frequencies.
When operating in very clear water or greater depths, increase the sensitivity to see weaker returns that may be of interest . If the sensitivity is adjusted too high, the display may become too cluttered.
Decrease t he s ensitivity to elimina te th e clut ter fro m the d isplay that is sometimes present in murky or muddy water. If Sensitivity is adjusted too low, the display may not show many sonar returns that could be fish.
NOTE: The Sensitivity setting is a global setting and will adjust the sensitivity of all sonar frequencies.
Sensitivity at Low Sensitivity at Medium Sensitivity at High
Upper Range
(Advanced: Sonar, Split Sonar, Circular Flasher, and Big Digits Views only)
Settings: 0 to 990 ft or 0 to 327 m [International Models only]; Default = 0
Upper Range sets the shallowestdepth range that will be displayed onthe Sonar, Split Sonar, Circular Flasher, and Big Digits Views. Upper Range is often used with Lower Range.
For example, if you are only interested in the area between 20 and 50 feet deep, you should set the Upper Depth Range to 20 and the Lower Depth Range to 50. The Sonar View will then show the 30 foot area between 20 and 50 and will not show the surfac e or the bottom (assuming the bottom is deeper than 50 feet). Greater detail will be shown for the area between 20 and 50 feet.
NOTE: A minimum distance of 10 feet will be maint ained between the Upper and Lower Range regardless of the manual settings entered.
Lower Range
Settings: AUTO, 10 to 1000 ft, 3 to 330 m [International
Models only]; Default = AUTO
Lower Range sets the deepest depth range that will be displayed by the unit.
Auto: The L ower Range will be adjus ted by the unit to f ollow the bottom automatically. Auto is the default setting.
Manual: You can adjust the Lower Range to lock the unit on a particular depth. ???M??? will be displayed in the lower right corner of the screen to indicate the unit is in Ma nual mode. Adjus t the Upper an d Lo wer Ra nge to gether to view a specific depth range, especially when looking for fish or bottom structure.
For example, if you are fishing in 60 feet of water but are only interest ed in the first 30 feet (surface to a depth of 30 fe et), you should set the Lower Depth Range limit to 30. The display will show the 0 to 30 foot range, which allows you to see a more detailed view than you would see if the dis play went all the way to the bottom.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered.
Chart Speed
Settings:
Fastest; Default = 5
Chart Speed determines the speed at which the sonar information moves across the display, and consequently the amount of detail shown.
A faster speed shows more information and is preferr ed by most ang lers; however,the sonar information movesacross the display quickly. A slower speed keeps th e i nformation on the display longer, but t he bottom and fi sh details become compressed and may be dif ficult to interpret. Regardless of the Chart Speed setting, the RTS Window??? will update at the maximum rate possible for the depth conditions.
Bottom View
Settings: Inver se, Structure I D??, WhiteLine???, Bottom
Black; Default = Inverse
Bottom View selects the method used to represent bottom and structure on the display. See What???s on the Sonar Dis play: Bo ttom Pr esentation for more information.
Bottom Range
(Sonar Zoom View only when Bottom Lock is On)
Settings: 10 - 6 0 feet,
Bottom Range allows you to control how much of the water column, measured up from the bottom, is shown in the Sonar Zoom View. Choose a small value to see
NOTE: It is possible to set the Bottom Range to be greater than thedepth. In this case, you may see surface clutter in a wavy band that mirrorschanges in the depth.
Bottom Lock
(Sonar Zoom View only)
Settings: Off, On; Default = Off
Bottom Lock changes the mode of t he zoomed view in the Sonar Zoom View. Bottom Lock continuously graphs the bottom at a constant point on the display regardless of changes in depth. This ???flattens??? out the bottom contour but is effective at showing fish on or near the bottom.

Sonar Menu, Advanced Mode
Beam Select
Settings: 200/83 kHz, 200 kHz, 83 kHz; Default = 200 kHz
Beam Select sets which sonar returns from the transducer will be displayed on the screen.
When set to 200/83 kHz, the returns from both beams are blended by starting with the 83 kHz wide beam return, dimming it, and then overlaying it with the
200 kHz narrow beam return. The darker 200 kHz narrow beam sonar returns will stand out from the paler 83 kHz wide beam sonar returns. The Split Sonar View continues to display the sonar returns from each beam in their respective windows. The blended informat ion is shown in the Son ar View, Sona r Zoom View, and the Big Digits View. The RTS Windo w??? in the Sonar View and the Circular Flasher View will only show the returns from the 200 kHz narrow beam.
When set to 200 kHz, only the returns fro m the 200 kHz narrow beam will be displayed in the Sonar View, the Sonar Zoom View, the Big Digits View, and the Circular Flasher View. The SplitSonar View will continue to display returns from both beams in their respective windows. The RTS Window??? in the Sonar View will display the returns from the 200 kHz narrow beam.
When set to 83 kHz, the returns from the 83 kHz wide beam will be displayed in the Sonar View, the Sonar Zoom View, the Big Digits View, and the Circular Flasher View. The Split Sonar View will continue to display returns from both beams in their respective windows. The RTS Window??? will display the returns from the 83 kHz wide beam.
Surface Clutter
Settings: Low = 1 to High = 10; Default = 5
Surface Clutter adjusts the filter that removes surface clutter noise caused by algae and aer ation. The lower t he set ting, th e less sur face clutter will be displayed.
Surface Clutter

Clutter
SwitchFire???
Settings: Clear Mode, Max Mode; Default = Clear Mode
SwitchFire??? controls how the sonar returns are displayed in the Sonar Views.
Choose Max Mode to see only raw sonar returns on the d isplay. When Max Mode is selected, you will see the maximum sonar information available within the transducer beam, so more fish arches and better jig tracking are shown.
Choose Clear Mode to see less c lutter and mo re fish size a ccuracy on the display. When Clear Mode is selected, the clutter is filtered, and sonar returns are interpreted to provide more details about the objects within the transducer beam, regardless of their locat ion. In other words, a large arch on the display means a large fish has been detected.
Fish ID+???
Settings: Off, On; Default = Off
Fish ID+??? uses advanced signal processing to interpret sonar returns and will display a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Three different fish size icons represent the intensity of the sonar return and provide an indicator ofrelative fish size.
DualBeam PLUS ??? sonar models represent targets detect ed in th e 200 kHz narrow beam as Shaded Fish Symbols and targets detected in the 83 kHz wide beam as Hollow Fish Symbols.
When Fish ID+??? is t urned o ff, t he Fishfin der shows o nly the r aw son ar returns on the display. These returns will often result in ???arches??? forming on the display, indicating potential targets. D ue t o t he t ransducer b eam angle, the distance to a f ish decreas es as the fish moves into the beam, and then increases as it moves out again, creating a Fish Arch when this distance change is shown on the display. Boat speed, chart speed, and the position of the fish within the sonar beam greatly affect the shape of the arch.
Transducer Cone and Fish Arches
Fish ID Sensitivity
Settings: Low = 1, High = 10; Default = 5
Fish ID Sensitivity adjusts the threshold of the Fish ID+??? detection algorithms. Selecting a higher setting allows weaker returns to be displayed as fish. This is useful for identifying smaller fish species or baitfish. Selecting a lower setting displays fewer fish from weak sonar returns. This is helpful when seeking larger species of fish.
Fish ID Sensitivity is used in conjunction with Fish ID+???. Fish ID+??? must be On for Fish ID Sensitivity to affect the ability of the Fishfinder to identify sonar returns as fish.
Real Time Sonar (RTS???) Window
Settings: Wide, Narrow, Off; Default = Narrow
RTS Window??? sets the RTS Window??? to either Wide or Narrow, or turns it off in th e Sonar View . The RTS Window ??? always updates at the fa stest r ate possible and only displays ret urns that are within the transducer beam. See
What???s on the Sonar Display for more information.
NOTE: The Wide RTS Window??? does not use grayscale.
Zoom Width
Settings: Narrow, Medium, Wide; Default = Wide
Zoom Width adjusts the width of t he zoomed view on the Sona r Zoom View, which is on the left side of the display. See Views: Sonar Zoom View for more information.
83 kHz Sensitivity
(Advanced)
Settings:
83 kHz Sensitivity changes the sensitivity of the 83 kHz beam. Increasing the
83 kHz Sensitivity will display additional weak returns, and d ecreasing the 83 kHz Sensitivity will display fewer weak returns.
NOTE: 83 kHz Sensitivity is particularly useful for adjusting the sensitivity of the 83 kHz sonar returns in the 200/83kHz Split Sonar View. The 83kHz sensitivity can be adjusted without affecting the sensitivity of the 200 kHz re turns shown in the 200 kHz sonar window.
Depth Lines
(Advanced)
Settings: Off, On; Default = On
Depth Lines divide the display into four equal sections which are separated by three horizontal depth lines. The depth of each lin e is displayed along the depth scale. You can turn Depth Lines On or Off.
Depth Lines
Depth Lines
Noise Filter
(Advanced)
Settings: Off, L ow, Medium, High1, High2 , H igh3;
Default = Low
Noise Filter adjusts the s onar Noise Filter t o limit in terference on the display from sources such as your boat engine, turbulence, or other sonar devices.
The Off se tting removes all filtering. Low , Medium, and High1, High2, High3 settings add progressive filtering of the sonar returns. High1, High2, and High3 are useful when there is excessive trolling motor noise, but in some deep water situations, the High settings may actually hinder your unit???s ability to find the bottom.
Max Depth
(Advanced)
Settings: AUTO, 10 to 1000 ft, 3 to 330 m [International
Models only]; Default = AUTO
Max Depth controls the maximum depth of operation. When Max Depth is set to Auto, the Fish finder w ill acquire bo ttom readings a s needed (w ithin the capacity of the unit). When Max Depth is set to match your fishing maximum depth, your Fishfinder will not attempt to acquire sonar data below that depth, so more detail will be shown on the screen.
NOTE: If the bottom is deeper than the Max Depth setting,the digital depth readout will flash, indicating that the Fishfinder cannot locate the bottom.
Water Type
(Advanced)
Settings: Fresh, Salt (shallow), Salt (deep); Default = Fresh
Water Type configures your unit for operation in fresh or sa lt water. In salt water, you can also choose the shallow or deep setting.
Water Type affects the accuracy of deep water dep th readings. In salt water, what would be cons idered a large fis h might be 2 to 10 times bigger than a large fish in fresh water (depending on the type of fish yo u are seeking). The salt water setting allows for a greater range in fish size adjustment to account for this difference.

Troubleshooting
Before contacting the Humminbird?? Customer Resource Center, please read the following section. Taking the time to review these tro ubleshooting guidelines may allow you to s olve a performance pro blem yourself, and therefore avoid sending your unit back for repair.
Fishfinder Doesn???t Power Up
If your Fishfinder doesn???t power up, use the Installation Guide that also comes with it for specific confirmation details, making sure that:
???The power cable is properly connected to the Fishfinder control head.
???The power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground.
???The fuse is operational.
???The battery voltage of the power connector is at least 10 Volts.
Correct a ny k nown problems, including removing corrosion from th e battery terminals or wiring, or actually replacing the battery if necessary.

???Check the tr ansducer cable. Replace th e tra nsducer if t he ca ble is damaged or corroded.
Display Problems
There are several main conditions or sources of possible interference that may cause problems w ith the quality of t he in formation displayed on the control head. Look in the following table for some symptoms of display problems and possible solutions:
The control head loses If the power output of your boat???s engine is unregulated, power at high speeds. the co ntrol hea d ma y b e prot ecting i tself u sing i ts
voltage does not exceed 20 Volts.
When the boat moves at higher speeds, the bottom disappears or suddenly weakens, or the display contains gaps.
The transducer position may need to be adjusted. A mix of air and water flowing around the tr ansducer (cavitation) may be interfering with the interpretation of sonar data. See your Installation Guide for suggestions on adjusting the transducer position.
Electrical noise from the boat???s engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.
There are no fish detected, even when you know they are in the water under the boat, or sonar readings seem weak or faulty.
Sonar readings may be affected if the transducer is not positioned correctly (i.e. mounted at an angle, not straight down), or there is some kind of mechanical interference, either because it is mounted inside a hull that is too thick for p roper son ar transmission, the bond betwe en th e transducer a nd the hull is not a irtight, or because the transducer is dirty.

Low battery voltage may be affecting the power of signal transmission.
Electrical noise from the boat???s engine may be interfering with sonar reception. See Finding the Cause of Noise for more information.
Finding the Cause of Noise
Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity readings. One or more of the following sources can cause noise or interference:
Cavitation from the boat???s propeller
Turbulence created by the pr opeller can cause noise; m ake sure t he tr ansducer i s mo unted at least 15??? (38 cm) from the propeller, and that the water flows smoothly over the face of the transducer at all times.

Glossary
Sonar Terms:
Beam (Sonar Beam) The wide,
Bottom Contour The profile of the bottom graphed to the display as thedepth changes.
Bottom Hardness The density (or composition) of the bottom. Varying levelsof hardness can be determined by interpreting the ???thickness??? of the main sonar return. Hard returns appear thin and black, softer returns appear thicker and less black. It is important to note that a sonar return from a sloping bottom can have the appearance of a softer bottom.
Cavitation The effect of air bubbles created as the propeller rotates and the boat moves through the water.
Cone Angle The angular measurement of the sonar beam at a specific dB down point (i.e.
Dead Zone The area of the sonar beam that receives the sonar signal after the main bottom return. Fish and other objects close to the bottom that fall within the dead zonewill probably not be visible in the sonar beam. Precision sonar beams, such as the Humminbird?? 20?? beam, have a smaller dead zone than wider sonar beams.
Decibel The measurement for sound pressure level, or ???intensity???of the sonar return.See
dB Down Point.
dB Down Point The standard decibel level at which the sonar cone angle is measured, and is written as ???@
Display,FSTN (Film
Frequency A measure ofthe number of sound wave cycles per second of a soundimpulse transmitted underwater. A typical frequency for fishfinders is 200 kHz, which offers a good balance of performance under many conditions. Lower frequencies, such as 50 kHz, are capable of penetrating to greater depths, but with less resolution. Higher frequencies, such as 455 kHz, offer greater resolution, but are limited in depth performance. Humminbird?? uses a variety of frequencies that are optimized for specific applications.
Grayscale The use of varying shades of gray to represent the strength of the sonar signal on the display. Traditionally, the strongest sonar signals a re represented in black, and progressively weaker signals are represented in progressively lighter shades of gray.
Noise The unintentional, external sound waves that interfere with the optimal operation of sonar. Noise appears as random ???dots??? on the d isplay and is caused by a varie ty of sources. Many Humminbird?? products have a Noise Filter menu setting that allows the user to clear the screen ofnoise that is difficult to eliminate(also, see Troubleshooting).
Pixels The ???picture elements???, or small square blocks, that make up the image onthe LCD. Measured as a v ertical by horizontal number (i.e. 6 40V x 32 0H), this k ey specification typically indicates t he quality of r esolution. In fishfinders, the total resolution (vertical multipliedby horizontal) is often less important than the ???Vertical Pixel??? resolution because a greater number of vertical pixels provide finer resolution of targets detected by sonar. Sonar informationon the horizontal axiscan vary greatly, depending on boat speed and the Chart Speed setting.
Power Output The amount of sound energy emitted into the water by the transducer???s transmitter. Poweroutput is measuredusing either RMS (Root Mean Square) or
Pulse Width (Pulse Length) The length of time that a sonar sound burst is transmitted into the water.Shorter pulse widths provide better target separation, but cannot travel to great depths. Longer pulse widths provide better depth penetration, but result in poorer target separation.Humminbird?? varies pulse width based on depth to optimize both target separation and depth performance. See TargetSeparation.
Second Return Describes the appearance of a second sonar return below the primary sonar return (bottomcontour) at exactly twice the true depth. The second return is caused by the same sonar energy bouncing off the bottom once, rebounding to the water surface and then travelingback down to the bottom to be reflected again. Second returns are more common in shallow water and over hard bottoms; it is possible to see a third sonar return under some circum stances. The sec ond return provide s use ful info rmation to help determine bottom hardness, as areas with harder bottoms will generally create a second return. The second eturnr can beused as a guide to set Sensitivity when in shallower water.
SONAR (SOund and NAvigation Ranging) Sonar technology uses precision sound bursts transmitted underwater to determine the distance and other attributes of objects in the water. Distance can be determined because the speed of sound in water is constant, and the time for the s ignal to r eturn i s me asured. So und also travels v ery q uickly underwater, makingsonar a responsive,
Sonar Update Ra te The num ber of times per second that the transducer???s transmitter/receiversends and receives sonar signals. A very fast sonar updateratecollects more informationand provides a more detailed image of the b ottom, fish, and structure. Many Humminbird?? units operate at up to 40 times per second when in single frequency operation. Due to the limitation ofthe speed of sound in water, the update rate begins to slow as depth increases to deeper than 50 feet. In very shallow water (less than 10 feet), however, update rates as much as 60 times per second can be achieved.
Speed The rate at which the boat moves through the water. Boat speed can be measured as Speed Over Ground orSpeed Through Water. Speed Over Ground is provided by GPS, and is the measurement of the boats progress across a given distance. Speed Through Wateris provided by a speed paddlewheel, and is the measurement of the flow past the boat, which may vary depending on current speed and direction. Speed Through Water is most critical for anglers using downriggers, as it impactsthe running depth of the down riggers. Speed Over Ground is optimal for navigation, as accurate destination times can be derived from this measurement. Humminbird?? products allow for input and display of both sources.
Structure A general term for objects on the bottom that present a discontinuity andare a likely attractor for fish. This includes bottom contour features
Surface Clutter A phenomenon where sonar returns are reflected off of tiny objects near the s urface of the water , inc luding alg ae and eve n air bubb les. Typically, saltwater environments have significantly greater surface clutter than freshwater due to continuous wind and wave action that causes aeration at the surface.
Target Separation The measurement of minimum distance that a fishfinder needs to be able to recognize two very close objects as two distinct targets (i.e. two fish hanging very close, or a fish hanging very clos e to structure). Humminbird?? fishfinders provide a v ery good 2 1 /2 inches of ta rget s eparation in shallower than 100 f eet of depth. Target separation decreasesas depth increases due to the need for longer Pulse Width to achieve greater depth. See Pulse Width.
Thermoclines Water layer(s) of disti nctly di fferent temperatures that c reate a sonar reflection due tothe densityof the differing water temperatures. Typically a thermocline will appear as a continuous band crossa thedisplay at somedistanceabove the bottom contour. Thermoclines are of interest to angler s b ecause fish will su spend ab ove or b elow the thermocline as theyseek the optimum temperature and oxygen levels.
Time VariableGain (TVG) A processing step applied to the sonar return to ???normalize??? the data so that objects of equal size (i.e. fish) appear to be the same size, even if they are separated by a good distance.
Transducer The transducer is part of the sonar system, which mounts on the boat and is in contact with the water, that con verts the electrical energy from the transmitter into sound energy, andthat forms the sonar beam in turn. Internaly, the transducer consists of one or more piezo electric disks that expand by very minute amounts to create the sound wave. This elementalso works in reverse, converting the returned soundenergy back into an electrical signal that the receiver interprets. See SONAR.
Zoom A f eature t hat foc uses on a smaller are a of the b ottom to p rovide enhanced resolution. With enha nced resolution, the ang ler can mo re easi ly see fish hanging in structure or multiple fish hanging close together.
Zoom, Bottom Lock Bottom Lock Zoom is a feature that focuses on a smaller area just above the bottom to provide enhanced resolution. Unlike regular zo om, it continuously graphs the bottom at a constant point on the display regardless of changes in depth. This ???flattens??? out the bottom contour, but is effective at showing fish on or near the bottom, and is preferred bymany saltwater anglers.
GPS & Navigation Terms:
Acquisition Time The length of time that a GPS receiver typically takes to determine a position from at lea st three satelli tes. Hu mminbird?? GPS rece ivers p rovide ver y fast acquisition times (underone minute), permitting users to get out on the water faster.
Altitude The height measurement above sea level. Altitude is a measurement that can be provided by GPS.
Bearing (BRG) The direction to a destination waypoint measured in degrees from North (i.e. 321??, where 000?? is North, 090?? East, 180?? is South, 270?? is West).
Chartplotter A navigation device that shows Present Position on a M ap, along with Tracks, Waypoints,and Routes. All Chartplotters are also considered Trackplotters.
Cold Start The procedure that a GPS r eceiver must perform when it d oes not have historical information egardingr its current location. This procedure typically lasts for several minutes, and may be experienced upon first power up of the receiver, or if the receiver has been moved a great distance.
Course Over Ground (COG) The current direction the boat is traveling measured in degrees from North (i.e. 321??, where 000??is North, 090?? East, 180?? is South, 270?? is West). When the Course Over Ground is equal toBearing, the boat is said to be ???On Course??? and will arrive at the dest ination in the most efficient manner. COG is o ften confused with Heading. See Heading.
Cross Track Error (XTE) The
Track.
DifferentialGPS (DGP S) A system used to improve the p osition ac curacy of the Department of Defense GPS through the use of secondary ???correction signals??? broadcast from ground stations around the coastal United States and on some inland waterways. These correction signals are provided by the USCG and received by an auxiliary Differential Beacon Receiver (DBR) that connects to the GPS receiver. The advent of WAAS has largely negated the need for the added expense of a DBR in the United States.
Distance ToGo The
to Go and Speed Over Ground.
Estimated Position Er ror (EPE) A calculation that i ndicates th e p otential p osition inaccuracy the usermay experience due to a variety of GPS factors which include satellite position in the sky, signal strength, and others factors.
Fix Type Indicates whether the GPS receiver is providing 2D fix or 3D fix. A 2Dfix requires only three satellitesand provides only latitude and longitude. A 3D fix requires four or more satellites, and provides latitude, longitude, and altitude.
GPS (Global Positioning System) GPS provides accurate position (latitude, longitude, altitude) information virtually a nywhere on th e earth through sa tellite technology and personal receiverson the ground. SeeHow GPS Works.
Heading The direction the boat is pointing and is measured in degrees (i.e. 321??, where 000?? is North, 090?? East, 180?? is South, 270?? is West). Due towind and waves, the boat is often traveling ina slightly different direction than it is heading, and therefore Heading is often confused with Course Over Ground. See Course Over Ground.
Map Datum Refers to a particular survey of the earth???s surface that was referenced when creating a chart (ie. . WGS84).It is important to select the corect Map Datum setting in your fishfinder when c omparing GPS posi tion to a pape r cha rt to a void slight positio n inaccuracies. Almost all electronic charts use the WGS84 Map Datum and therefore, they do not require setting changes.
MMC (Multi Media Card) An MMC is a postage
North, Magnetic The pr inciple reference po int of the co mpass (i.e . Nor th is 0 00??). Magnetic North relies on the ea rth???s magnetic field to align a metal pointer generally towards True North. However, due to localvariations in the earth???s magneticfield around the globe, the difference between True Northand Magnetic North can be greater than10??. See True North.
North, True The principle reference point of the compass (i.e. North is 000??). True North uses the axis of the rotation of the earth as the reference for North and is constant for all points on the earth. Most GPS units default to True North as the setting. The GPS heading may vary from the boat compass heading because the compass uses Magnetic North. See
Magnetic North.
Present Position The c urrent location (l atitude, lo ngitude) de termined b y G PS. The Present Position is indicated
Route A series of waypoints linked together in a specific sequence to define a navigation path between two points, and saved in the fishfinder???s memory. Routes are often used when frequently traveling between two or more locations because it is a faster and more accurate method t han repeatedly selecting individual w aypoints each time one travels through the same area. Routes consist of a Start Waypoint, an End Waypoint, and a series of waypoints in between. Users can begin navigation at the beginning, the end(to run the route in reverse) or at any waypoint inbetween. See Waypoint.
SD (Secure Digital) An SD card is virtually identical in function to an MMC; however, the speed atwhich information can be accessed is generally faster, the storage capacity is generally larger, andhet card has security features which can be used to prevent extracting the data from the card. SD is the same format that many digital cameras use. See MMC.
Selective Availability (SA) A GPS system ???feature??? that can be implemented by the U.S. Department of Defense (DoD)to degradethe accuracy of GPS positioninginformation. With SA active, the GPS is accurate to within 100 meters 95% of the time. With SA inactive,the GPS is accurate to within 45 m eters 95% o f the time. Currently, SA is inactive and the consumer can enjoy the greater precision GPS p rovides; however, the DoD reserves the right to activate SA at any time.
Speed Over Ground (SOG) The measurement of the boat???s progress across a given distance and the speed measurement provided by GPS. An alternate, Speed Through Water, is provided by a speed paddlewheel, and is the measurement of the flow past the boat, which may vary depending on current speed and direction. Speed Over Ground is optimal for navigation because accurate destination times can be derived from this measurement. Humminbird?? products allow for input anddisplay of both speed measurements.
Time To Go (TTG) The estimated time required to reach the destination waypoint. TTG is calculated using the SOG and DTG. See SOG and DTG.
Track A series of saved points that define the past path of theboat. TheseTrack Points are saved at regular time intervals. Tracks are a useful and quick method to see where you???ve been, and an easy guide to follow to get you back to the starting point. Generally,all GPS units have a limited number of Track Points that can be saved before the unit runs out of memory and beginserasing the first trackpoints saved. Because of this, the user can adjust the Track Point Interval menu to increase the amount of time between when points are saved, and thus extend the distance covered by a track. Tracks can also be permanently saved to memory and
Track Line (TRK) The planned line of travel between two waypoints, and it represents the most efficient path between the two points because it is a s traight line. The TRK is measured in degrees (i.e. 321??, where 000?? is No rth, 090?? East, 180?? is South, 270?? is West). See Cross Track Error and Course Over Ground.
Trackplotter A navigation device that shows Present Position, along with Track,Waypoint, and Routes,but NO MAP in the background. See Chartplotter.
Trolling Grid A Humminbird?? feature that displays a pr ecise reference grid around a waypoint. This grid is used as aguide pattern for trolling around a specific area to assure a more efficient and complete coverage of that area.
UTC (Universal Time Constant) UTC is the ???standard time??? used in navigation and is the local time in Greenwich England. (UTCis equivalent toGreenwich Mean Time (GMT)).
WAAS (Wide Area Augmentation System) WAAS is complementary technology to GPS that provides enhanced accuracy through correction signals broadcast from Federal Aviation Administration WAAS satellites stationed over the USA. These secondary signals are automaticallyreceived by the standard Humminbird?? GPS Receiver. With WAAS signal, GPS accuracy is improved to within 3 meters 95% of the time. Outside the United States, regional governmental coalitions have created similar systems such as EGNOS (Europe) and MSAS (Japan).
Waypoint The saved location (latitude, longitude) of a point of interest that is storedin a GPS receiver???s memory. This can include a marker buoy, dock, fishing hole, or anywhere else the user may want to return to. Humminbird?? products offer the ability to name and assign a symbol to the saved location. Depth, Date, and Time of Day when the waypoint was created is also saved.
Waypoint Target A Humminbird?? feature that displays a precise ???bull???s eye??? around a selected waypoint. This bull???s eye is use d to easily monito r bo at position relative to a waypoint, and is useful for fishing over submerged structure. With Waypoint Targets,a quick look at the screen lets you know how far off the waypoint the boat has drifted.
