2 How Sonar W orks Sonar technology is based on sound waves. The 100 Series™ Fishing Syst em uses sonar to locate and define structure, bot tom cont our and composition, as well as depth directly below the transducer . Y our 100 Series™ Fishing System sends a sound wave signal and determines distance by measuring the time between the transmissi[...]

4 3 What’ s On the Display The 100 Series™ Fishing System can display a variety of useful information about the area under and adjacent to y our boat, incl uding the following items: Depth - water depth; can be set to alarm when the water becomes too shallow . T emperature - water surface temperature. Timer - Elapsed time with T emp/Speed Acces[...]

Views The views available on your 100 Series™ Fishing Syst em are: • Sonar View • Zoom View • Big Digits View • Circular Flasher View . Sonar View is the default view .
