Using the Pointer on the Sonar Page Y ou can show the pointer (arrow) to reference sonar items and mark underwater waypoints. This makes it easier to find and use an object such as a stump for a future fishing location. When using this feature, the Sonar Page pauses. The depth continues to update while the display is paused, but the unit does not[...]

Depth Number —select how efficient the digital depth update rate is. Fast Update updates quicker and is recommended for low-noise water deeper than 50 feet. Auto is best for shallow water or high- noise areas, has a slower screen update, and is best used if you travel a wide variety of depths. If the unit is unable to track the bottom for any re[...]

Changing the T emperature Display The graph will adjust and show the temperatures changes according to the T emperature Scale and T ime Duration settings. 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. Time Duration —set [...]

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. Understanding the Sonar Di[...]

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. As shown in the drawing on the far right, the 10° cone angle produces a [...]

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. Normally , a red line is used to show [...]
