Depth Line—adds a horizontal depth line across the screen that is
used to measure the depth of underwater objects. The depth of the
line appears in a box on the right side of the line. Press up or down
on the roCKEr to move the line on the Sonar Page.
noise reject—helps filter unwanted noise from the Sonar Page.
The Noise Reject can be turned off, set to normal (automatically
adjusts for optimum viewing) or to a fixed 1–100% setting. When
setting the Noise Reject, remember that a higher noise rejection
setting is less likely to show fish or structures.

the screen pauses, but the unit does not show any new sonar data
until the Sonar Page resumes scrolling.

and press ENTER.

appropriate field and press ENTER. Make your changes, and
press ENTER when done.
4. When finished, highlight OK, and press ENTER.

MENU, highlight Hide Pointer, and press ENTER.
