T emperature Scale —select a degree span from the list. Select Auto to have the unit automatically determine the best range, or select a span of 2, 4, 6, 8, or 10 degrees.
Generally speaking, if the only thing between the transducer and the bottom is water , the first strong return comes from the bottom directly below the transducer and sets the bottom level. W eaker secondary returns provide the detailed data. Stronger returns display in darker colors, with red being the strongest return.
The narrow cone angles (10°) associated with high frequencies (200 kHz) provide better bottom resolution and crisper detail, but cannot show a large coverage area for finding fish. The 10° cone angle provides a coverage width that is approximately 2/10 of the water depth.
Whiteline The GSD 20 Sounder Module can help you determine whether the bottom is hard or soft. When the sonar sound waves are reflected back by the bottom, a hard bottom returns a stronger signal than a soft bottom. A thin whiteline indicates a softer bottom, while a thick whiteline indicates a harder bottom.
