Shallow Area
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.
