Depth Lines
(Advanced)
Depth Lines divide the display into four equal sections that are separated by three horizontal
depth lines. The depth of each line is displayed along the depth scale. You can either turn Depth
Lines On or Off. The Depth Lines menu choice is available when User Mode is set to Advanced (see
Setup Menu Tab: User Mode).
To change the Depth Lines setting:
1. Make sure you are in Advanced User Mode, then highlight Depth Lines on the Sonar
main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Depth Lines setting On or
Off. (Off, On, Default = On)
