Bottom-zoom display

Zoom marker (yellow)

This mode expands bottom and bottom fish echoes two to five times to vertical size of the screen, and is useful for determining bottom hardness. A bottom displayed with a short echo tail usually means it is a soft, sandy bot- tom. A long echo tail means a hard bottom.

Data display

This display provides navigation data in digi- tal form. Date, time, position, course, speed, depth, water temperature and waypoint data can be shown. Requires nav data input and appropriate sensors.

The bottom-lock display provides a com- pressed normal picture on the right half of the screen and a 5 or 10 meter (10 or 20 feet) wide layer in contact with the bottom is expanded onto the left half of the screen. This mode is useful for bottom discrimination.
