4. VIDEO SOUNDER OPERATION

Bottom-lock display

The bottom-lock display provides a compressed normal picture on the right half of the screen and a 10 or 20 feet (3 or 6 meter) wide layer in contact with the bottom is expanded onto the left half of the screen. This mode is useful for discriminating bottom fish from the bottom echo. You may select the bottom lock range from the SOUNDER RANGE SETUP menu. For details, see paragraph 5.9.3.
