How Sonar Works

Sonar technology is based on sound waves. The 500 Series™ Fishfinder uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer.

Your 500 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 teardrop-shaped beam.

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.

How Sonar Works

Page 13

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.

455kHz

Your Fishfinder uses Down Imaging™ technology. The Down Imaging™ transducer scans the water with razor-thin, highdefinition beams. The beams are wide (side to side) but very thin front to back.

The Down Imaging™ beams can be operated at two frequencies: 455 kHz (75°) or 800 kHz (45°). Select 455 kHz for the best overall image quality and depth. Select 800 kHz for the sharpest image. See Down Imaging™ X-Press™ Menu: Imaging Frequency for more information.

The transducer also uses conical beams to provide data in traditional 2D format (see What’s on the Sonar Display). Select 455 kHz for a narrowly focused 16° center beam, or select 200 kHz for a wider 25° beam (see Sonar Menu Tab: Beam Select).

Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

How Sonar Works

Page 15

How GPS Works

Your 500 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 5 updates per second, 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 +/- 10 meters, depending on conditions. This means that 95% of the time, the GPS receiver will read a location within 10 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 500 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 SD Memory Card Slot: Add Maps to Your Fishfinder for more information.

What’s on the Sonar Display

The 500 Series™ Fishfinder can display a variety of useful information about

Depth - Water depth; can be set to alarm when the water becomes too 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 statute miles traveled.

Temperature - Water surface temperature.

Timer - Elapsed time with Temp/Speed

Accessory or GPS Receiver.

Distance - Distance traveled with Temp/Speed Accessory or GPS Receiver.

Average Speed - Average speed reading with Temp/Speed Accessory or GPS Receiver.

Second Sonar Return - When the sonar signal bouncesbetween thebottom andthesurface ofthe water and back again. Use the appearance of the second return to determine bottom hardness. Hard bottomswill show a strongsecondreturn,whilesoft bottoms will show a very weak one or noneat all.

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.

NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either the information from the GPS receiver will be displayed on the view.

Bait Ball

Hollow Fish Symbol (See Fish ID+™)

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.

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.

What’s on the Sonar Display

Page 18

Understanding the Sonar Display

It is important to understand the significance of the display. The display does not show a literal 3-dimensional representation of what is under the water. Each vertical band of data received by the control head and plotted on the display represents something that was detected by a sonar return at a particular time. As both the boat and the targets (fish) may be moving, the returns are only showing a particular segment of time when objects were detected, not exactly where those objects are in relation to other objects shown on the display.

The returned sonar echoes are displayed on the screen. As a new echo is received, the historical data scrolls across the screen.

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 Window™ 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 grayscale used matches the Bottom View grayscale setting (Inverse, StructureID WhiteLine™, Bottom Black). The depth of the sonar return is indicated by the vertical placementof the returnon the display depth scale.

What’s on the Sonar Display

The Wide RTS Window™ indicates the sonar intensity through the use of a bar graph. The length of the

plotted return indicates whether the return is weak or strong. The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale. The Wide RTS Window™ does not use grayscale.

Page 19

SwitchFire™

SwitchFire™ controls how the sonar returns are displayed in the Sonar Views. SwitchFire™ settings are available in the Sonar Menu Tab.

To see the maximum sonar information available within the transducer beam so more fish arches and better jig tracking are shown, choose Max Mode.

To see less clutter and more fish size accuracy interpreted from the transducer beam, choose Clear Mode. See Sonar Menu Tab: SwitchFire™ for more information.

Freeze Frame and Active Cursor

Freeze Frame & Active Cursor - Press any arrow on the 4-WAY Cursor Control key, and the screen will freeze and a cursor will be displayed. Use the 4-WAY Cursor Control key to move the cursor over a sonar return, and the depth of the sonar return will be displayed at the bottom of the screen in the cursor information box.

The RTS Window™ continues to update in Freeze Frame. To return to a scrolling display and exit Freeze Frame, press the EXIT key. Freeze Frame is available in the Sonar, Split Sonar, and Sonar Zoom Views.

Instant Image Update

Instant Image Update - You can change a variety of sonar menu settings (such as Sensitivity or Upper Range), and the adjustments will be shown instantly on the screen.

Sonar Returns and Bottom View

As the boat moves, the unit charts the changes in depth on the display to create a profile of the Bottom Contour. The Sonar View displays the sonar return intensity using gray scale.

Strong returns often result from rocky or hard bottoms (compacted sediment, rocks, fallen trees), while weaker returns often result from soft bottoms (sand, mud), vegetation, and small fish.

The shades used to represent high, medium, to low intensity returns are determined by the setting you choose in the Bottom View menu option. See Sonar X-Press™ Menu to set the Bottom View.

Inverse is a method where weak returns are shown with dark pixels and strong returns with lighter pixels. This has the benefit of ensuring that weak signals will be clearly visible on the display.

Structure ID® represents weak returns as light pixels and strong returns as dark pixels. This has 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 distinctive 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 providing a high contrast between the bottom and other sonar returns on the display.

Depth - (water depth) can be set to alarm when the water becomes too shallow.

Temperature - Water surface temperature.

Topography Changes - The light part of the

display shows where the beam is hitting hard bottom or rising terrain. The dark part of the display indicates soft bottom (sand, mud) or descending terrain.

Speed- If a Temp/Speedaccessory is connected, the Fishfinder can display the speed of the boat and can keep a Triplog of nautical or statute miles traveled.

You can gain insight into the actual shape of an object, or the depth to which it has sunk into the bottom, through shadows on the display. Objects standing on the bottom cast a sonar shadow. The longer the shadow, the taller the object. Fish also cast shadows. You can use the shadow to interpret how close the fish is to the bottom.

Understanding the Down Imaging™ Display

The images you see on the Down Imaging™ display are produced using sonar technology. Each time the unit pings, a strip of data representing all the echoes received by the transducer are put together on the display to form the image that you see. Like traditional 2D Sonar, the sonar history scrolls left across the screen.

Interpreting the Display

Down Imaging™ beams “illuminate” the bottom contour, structure, and fish. The beams are wide (side to side) but very thin front to back.

Use the light and dark parts of the display to interpret the objects under your boat as follows:

• Dark shades represent soft returns (mud, sand) or descending terrain.

• Light shades represent denser terrain (timber, rocks) or rising terrain. A very hard bottom may appear as white on the display.

• White Streaks or Clouds may represent fish on the display.

• Shadows are not caused by light but by the lack of a sonar return. Objects standing on the bottom cause a sonar shadow to appear on the display. The longer the shadow, the taller the object. Fish may also cast shadows. You can use the shadow to interpret where the fish or object is located in relation to the bottom.

Introduction to Navigation

Your Fishfinder allows you to mark waypoints and start navigation with the control head keys or the Navigation X-Press™ Menu.

You can also use the Waypoint Management dialog box to create new waypoints and routes from scratch. You can edit your navigation data and organize it too. This section will get you started. See your Humminbird® Waypoint Management Guide for complete details.

Waypoints are stored positions that allow you to mark areas of interest or navigation points. Your Fishfinder can store up to 2,750 waypoints.

Introduction to Navigation

Page 43

Routes link two or more waypoints together to create a path for navigation and are used in trip planning. You can link individual waypoints together by using the GOTO key. Your Fishfinder can store up to 45 routes that can each contain up to 50 waypoints.

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 get to your destination, although you should always look out for obstacles not shown on the chart. A Route Leg is the path between each waypoint in a route.

Tracks consist of detailed position history and are displayed as a breadcrumb trail of trackpoints. The Current Track shows the position history since the unit was powered up. You can clear the Current Track or save it at any time. Your Fishfinder can store up to 50 saved tracks, each containing 20,000 trackpoints. The current track represents your actual path so far.

NOTE: The maximum number of waypoints and routes may vary due to the setup of your Waypoint Management directory. Groups and sub-groups also use storage, and the storage limit is influenced by the complexity of your Waypoint Management directory.

Sonar X-Press™ Menu

Page 76

Upper Range

(Advanced: Sonar and Big Digits Views only)

Settings: 0 to 790 feet or 0 to 257 meters [International Models only]; Default = 0 ft

Upper Range sets the shallowest depth range that will be displayed on the

Sonar 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 surface 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 maintained between the Upper and Lower Range regardless of the manual settings entered.

Lower Range

Settings: Auto to 800 feet, Auto to 260 meters [International Models only]; Default = Auto

Lower Range sets the deepest depth range that will be displayed by the unit.

Auto: The Lower Range will be adjusted by the unit to follow 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 Manual mode. Adjust the Upper and Lower Range together 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 interested in the first 30 feet (surface to a depth of 30 feet), 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 display 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.

Sonar X-Press™ Menu

Page 77

Chart Speed

Settings: 1 - 9, Ultra, where 1 = Slow, 9 = Fast, Ultra = 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 preferred by most anglers; however, the sonar information moves across the display quickly. A slower speed keeps the information on the display longer, but the bottom and fish details become compressed and may be difficult 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: Inverse, Structure ID®, 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 Display: Sonar Returns and Bottom View for more information.

Bottom Lock

(Sonar Zoom View only)

Settings: Off, On; Default = Off

Bottom Lock changes the mode of the 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 X-Press™ Menu

Page 78

Bottom Range

(Sonar Zoom View only when Bottom Lock is On)

Settings: 10 to 60 feet, 2 to 10 fathoms, or 3 to 20 meters (International Models only); Default = 15 ft

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 low-lying bottom structure or details of the bottom return. Choose a larger value to see large structure in deeper water.

NOTE: It is possible to set the Bottom Range to be greater than the depth. In this case, you may see surface clutter in a wavy band that mirrors changes in the depth.

Imaging Sensitivity

Settings: 1 to 20, where Low = 1, High = 20; Default = 10

Imaging Sensitivity (or Down Sensitivity) controls how the sonar returns are

displayed on the Down Imaging™ Views.

Increase the Imaging Sensitivity to reveal weaker returns that may be of interest, especially in very clear water or greater depths. A high imaging sensitivity setting shows more sonar returns from small baitfish and suspended debris in the water; however if the sensitivity is adjusted too high, the display may become too cluttered.

Decrease the Imaging Sensitivity to eliminate the clutter from the display that is sometimes present in murky or muddy water. If the sensitivity is adjusted too low, the display may not show many sonar returns that could be fish.

DI Enhance

Settings: Press the RIGHT Cursor key.

DI Enhance allows you to adjust your Down Imaging™ View in the following

categories: Sensitivity, Contrast, and Sharpness.

Whether you’re searching the Down Imaging™ data for fish or certain bottom contour, the most effective settings will vary with the situation. The display will update as you adjust each category.

For example, if you are fishing in 60 feet of water but are only interested in the first 30 feet (surface to a depth of 30 feet) 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 display 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 settings entered manually.

Chart Speed

Settings: 1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest; Default = 5

Chart Speed determines the speed at which the sonar information moves

across the display, and consequently, the amount of detail shown.

Surface Clutter

Settings: Low = 1 to High = 10; Default = 5

Surface Clutter adjusts the filter that removes surface clutter noise caused by

algae and aeration. The lower the setting, the less surface clutter will be displayed.

Surface Clutter

SwitchFire™

Settings: Max Mode, Clear 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 display. 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 clutter and more fish size accuracy 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 location. In other words, a large arch on the display means a large fish has been detected.

Sonar Menu Tab

Page 97

Fish ID+™

Settings: Off, On; Default = On

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 of relative fish size.

In Down Imaging™ models, targets detected in the 455 kHz conical beam are represented as hollow fish symbols, and targets detected in the 200 kHz conical beam are represented as shaded fish symbols.

Narrow Beam

Shaded Fish Symbols

Wide Beam

Hollow Fish Symbols

When Fish ID+™ is turned off, the Fishfinder shows only the raw sonar returns on the display. These returns will often result in “arches“ forming on the display, indicating potential targets. Due to the transducer beam angle, the distance to a fish decreases 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 the Sonar View. The RTS Window™ always updates at the fastest rate possible and only displays returns 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.

455 kHz Sensitivity

(Advanced, Down Imaging™ only)

Settings: -10 to +10, Default = 0

455 kHz Sensitivity adjusts the sensitivity of the 455 kHz beam. Increase the

sensitivity to display additional weak returns and decrease the sensitivity to display fewer weak returns.

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 line is displayed along the depth scale. You can turn Depth Lines On or Off.

Depth Lines

Noise Filter

(Advanced)

Settings: Off, Low, Medium, High 1, High 2, High 3; Default = Low

Noise Filter adjusts the sonar Noise Filter to limit interference on the display from

sources such as your boat engine, turbulence, or other sonar devices.

The Off setting removes all filtering. Low, Medium, and High1, High 2, High 3 settings add progressive filtering of the sonar returns. High 1, High 2, and High 3 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.

Sonar Menu Tab

Page 100

Max Depth

(Advanced)

Settings: Auto, 10 to 800 feet, 3 to 260 meters [International Models only]; Default = Auto

Max Depth controls the maximum depth of operation. When Max Depth is set

to Auto, the Fishfinder will acquire bottom readings as needed (within 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 salt water. In salt

water, you can also choose the shallow or deep setting.

Water Type affects the accuracy of deep water depth readings. In salt water, what would be considered a large fish might be 2 to 10 times bigger than a large fish in fresh water (depending on the type of fish you are seeking). The salt water setting allows for a greater range in fish size adjustment to account for this difference.
