• It is difficult to get fish arches in shallow water as the transducer sonar beam is very narrow near the surface and fish do not stay within the beam long enough to display an arch. Several fish in shallow water tend to display as randomly stacked blocks of pixels. • Wave motion may result in distorted fish arches 4-4 Gain Gain (sensitivity) controls the amount of detail displayed on the FISH 4432/4433. Understanding how to set suitable Gain settings is important for optimum performance.
