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. S

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

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 side-by-side. DualBeam PLUS™ is ideal for a wide range of cond

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

What’s on the Sonar Display The 300 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/

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,

U Un nd de er rs st ta an nd di in ng g t th he e S So on na ar r D Di is sp pl la ay y 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 part

S Sw wi it tc ch hF Fi ir re e™ ™ 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. F Fr re ee ez ze e F

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. Bottom Contour Profile w
