|In shallow water of 3~7.5ft (1~2.5M) signal reflection may show to erroneous information if it is a rocky or weedy area. In this case we suggest you replace 1 or 2 of the batteries with old ones in order to reduce power. Also, select sensitivity to "L" position and search again. Normally , the reading becomes better. Then, adjust bottom line down to lower on screen.|
|If the result is unsatisfactory, connect the power attenuator (Included) and adjust the control knob until the screen is clear. For even more clarity, make yourself a restrictor. This can be made simply with a piece of plastic sheet (approx. 5cm wide). It should look like a tube (see figure), and be fixed on the sonar. This addition will narrow the search angle and reduce mixed signals from reflection.This will give a sharp resolution on screen showing fish hiding under rocks or in complex habitats.|
