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:

• 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.

How Sonar Works

DualBeam Sonar

Your 500 Series™ 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.

How Sonar Works

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 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 +/- 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 Introduction to Navigation: Add Maps to Your Fishfinder for more information.

How GPS 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.

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 bouncesbetweenthebottom and thesurfaceof the water and back again. Use the appearance of the second return to determine bottom hardness. Hard bottomswillshowa strongsecond return,while soft bottoms will show a very weakone or none atall.

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 (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.

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.

Cursor - Available in Freeze Frame and can be positioned in the Sonar View to provide depth ofasonar returnand bottomdepth below the cursor.

UUnnddeerrssttaannddiinngg tthhee SSoonnaarr DDiissppllaayy

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.

RReeaall TTiimmee SSoonnaarr ((RRTTSS™)) WWiinnddooww

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 placement of the return on 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.

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. Pressing EXIT will exit Freeze Frame, and the display will start to scroll. Freeze Frame is available in the Sonar and Sonar Zoom Views.

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.

BBoottttoomm PPrreesseennttaattiioonn

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.

Both Chart and Combo Views allow you to choose the orientation of the view (see Navigation Menu Tab: Chart Orientation). In both orientations, the view pans automatically, so that the boat is always centered on the display.

• North-Up: True North is shown at the top of the display. Objects located

to the north of the boat are drawn above the boat.

• Course-Up: The direction of motion of the boat is shown at the top of the

display. Objects ahead of the boat are drawn above the boat.

When the boat is stationary, it is drawn as a circle. When the boat is in motion, it takes on a boat shape, pointed in the direction of motion (always Up in the Course-Up orientation).

In the Chart or Combo Views there are several cartography-related functions that you can access using various keys.

Panning: Use the 4-WAY Cursor Control key to move the chart around on the display in the direction of the key being pressed. When you do this, a bull's eye cursor is drawn at the center of the screen and is linked to the boat by a gray line, even if the boat is off the screen. At the same time, the temperature and speed boxes in the lower left corner are replaced with the distance and bearing from the boat to the cursor
