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

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:

How Sonar Works

• 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.

Single Beam Sonar

(550, 560)

The 550 Fishfinder and 560 Fishfinder use a 200 kHz single beam sonar system with a 20° area of coverage. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

How Sonar Works

DualBeam Sonar (570)

The 570 Fishfinder uses a 200/83 kHz DualBeam sonar system with a wide (60°) area of coverage. DualBeam sonar is optimized to show the greatest bottom definition using a narrow (20°) beam, yet can still indicate fish found in the wide (60°) beam when the Fish ID+™ feature is turned on. DualBeam is ideal for a wide range of conditions - from shallow to very deep water in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

DualBeam PLUS™ Sonar (561)

The 561 Fishfinder 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.

How Sonar Works

DualBeam PLUS™ sonar returns can be blended together, viewed separately, or compared sideby-side. DualBeam PLUS™ is ideal for a wide range of conditions - from shallow to very deep water in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

The 570 DI 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

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.

Temperature - Water surface temperature.

Timer - Elapsed time with Temp/Speed

Bait Ball

Hollow Fish Symbol (see Fish ID+™)

Thermoclines - Layers of water with different

temperatures that appear at different depths and different times of the year. A thermocline typically appearsas a continuous band of gray levels moving across the display at the same depth.

Structure - Where fish may be hiding.

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.

RTS (Real Time Sonar) Window™

Battery Voltage - The voltage of the boat’s

battery; can be set to alarm if the voltage falls below a certain point.

What’s on the Sonar Display

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 left across the view.

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 return onthe 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. Thedepth ofthe sonar return is indicated by the vertical placement of the return on the display depth scale. The Wide RTS Window™ does not use grayscale.

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 and 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 in the cursor dialog 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.

What’s on the Sonar Display

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 bottom can be determined 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.

The sonar returns from the bottom, structure, and fish can be represented as

Inverse, Structure ID®, WhiteLine™, or Black (Bottom Black). See Sonar X-Press™ Menu: Bottom View to set the Bottom View.

What’s on the Sonar Display

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.

What’s on the Down Imaging™ Display

Down Imaging™ uses its unique transducer and sonar technology to provide profiling beams produce the detailed sonar data that you see on the display. interpret the structure and bottom contour, including the following items:

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

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.

Bottom Return - Use the appearance of the bottom return to determine bottom hardness. Rock and gravel provide a clearer sonar return than mud and sand because hard objects reflect sonar better than soft objects.

Lower Range

What’s on the Down Imaging™ Display

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.

What’s on the Down Imaging™ Display

Down Imaging™ Sensitivity

Use Imaging Sensitivity to control how the sonar returns appear on the display. Increase the sensitivity to reveal weaker returns that may be of interest, especially in very clear water or greater depths. Decrease the Imaging Sensitivity to eliminate the clutter from the display that is sometimes present in murky or muddy water. See Down Imaging™ X-Press™ Menu: Imaging Sensitivity or Down Imaging™ Sensitivity for more information.
