The option selected currently appears in the upper left of the display. Press MENU and highlight Adjustments to see a list of all options and their current settings. To select an adjustment option from the Sonar Page: 1. Press the ROCKER left/right to scroll through the options in the upper left of the display. 2.
USING SONAR > SONAR PAGE Zoom Adjustment Range Adjustment Range—sets the display depth range used for viewing. The unit can be set to automatically track the bottom or set to a userspecified depth range. Auto Mode displays the most information possible while continuously showing the bottom. Zoom—used to quickly select a display zoom range or split the display. When a range other than No Zoom is selected, the Adjustment Menu displays a new selection labeled View.
USING SONAR > SONAR PAGE • Btm (Bottom) Split—shows two reduced pictures; the right at the original depth scale and the left showing sonar returns from the bottom up. All target depths read as a distance from the bottom. • Btm (Bottom) Lock—displays only the Bottom Lock picture (returns from the bottom up) on the full screen. However, if Dual Frequency Display is set to Split, then a 50/200kHz split screen appears. When activated, the zoomed picture becomes the Sonar Page display.
USING SONAR > SONAR PAGE Whiteline—controls how the unit displays information about the bottom type (hard or soft). With the Whiteline Off, the bottom return displays as red and contains no information on bottom hardness. With Whiteline set at Normal or 1-100%, the bottom return becomes white with a red line indicating where the water meets the bottom. To turn the Whiteline Off, press the ROCKER down until the setting bar is all the way at the bottom Whiteline Adjustment of the range and reads Off.

You can adjust the size of the split window anywhere from 1/4 to 3/4 width of the right half of the Sonar Page. Double-Arrow Fish Symbols—determines how the Sonar Page displays underwater targets and background information. If you select off, the unit does not show fish symbols.
USING SONAR > SONAR TAB OPTIONS Depth Number—controls the efficiency of the digital depth update rate. Fast Update updates more quickly and is recommended for low-noise, deeper water (>50 ft). Auto is best for shallow water or high noise areas, and produces a slower screen update. Use Auto when you travel a wide variety of depths. NOTE: If the unit is unable to track the bottom for any reason, the digits in the depth window flash on and off to alert you that the unit is not tracking the bottom.
USING SONAR > SONAR TAB OPTIONS Keel Offset—used to offset the surface reading for the depth of a keel. This makes it possible to measure depth from the bottom of your keel instead of from the transducer’s location. Enter a positive number to offset for a keel, or enter a negative number to compensate for a large vessel that can draw several feet of water. The Keel Offset reflects in the depth reading.
USING SONAR > SONAR TAB OPTIONS To calibrate the water speed: 1. On the Sonar tab, use the ROCKER to highlight Calibrate Water Speed and press ENTER. 2. Bring the boat to a cruising speed. The top ground and uncalibrated water speeds are shown at the bottom of the calibration window. Note your top water speed, then stop the boat and press ENTER. 3. By default, the top ground speed automatically displays in the What was your top water speed? field.
USING SONAR > SONAR TAB OPTIONS Understanding Sonar The transducer mounted on your vessel transmits sound waves toward the bottom of a lake, stream, or seabed in a cone-shaped pattern. When a transmitted sound wave strikes an underwater object—such as the bottom, a piece of structure, or a fish—sound is reflected back to the transducer. The transducer collects the reflected sound waves and sends the data to the GPSMAP 188/188C Sounder to be processed and displayed.
USING SONAR > UNDERSTANDING SONAR Transducer Coverage The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth. The wide cone angles (40°) associated with low frequencies (50 kHz) provide a large coverage area for finding fish within a coverage width that is approximately 2/3 of the water depth. However, this also means that wide cone angles produce less bottom detail and resolution.
USING SONAR > UNDERSTANDING SONAR Whiteline 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 the point where water meets the bottom. This line follows the bottom contour, along with any significant objects lying on the bottom.
