“WHITE LINE”: Used to monitor how the Fish Finder device displays

information about the nature of a bottom (soft or hard). The thin White Line

indicates a softer bottom whereas a thick White Line indicates a harder

bottom. When this function is set for “OFF”, the bottom return displays as

red and contains no information on bottom hardness.

“SENSITIVITY”: Quick Access to some of the most commonly used

controls for Fish Finder performance.

“FREQUENCY”: Changes the frequency of a sonar signal between 50kHz

and 200 kHz, providing optimal bottom and fish detection in both shallow

“DUAL FREQUENCY SCREEN”: Divides the screen to show the 50 Khz

images on one side and the 200 Khz images on the other side.

“RESET DEPTH LIMITS”: Allows the user to eliminate the Depth Limits

and start viewing the full or specified depth range.
