1.37.11 How to show/hide land trails (B-type only)
You can improve the on-screen display visibility by hiding trails generated by land-
masses and non-moving objects. Hiding the trails has the following possible benefits:
• Land-masses have no trail, allowing you to use relative trails near coastlines.
• Only moving echoes create a trail, improving target identification.
1. Select the [TRAIL] box at the bottom-right corner of the screen, then right-click to
display the [TRAIL MENU].
2. Select [9 HIDE LAND TRAILS(T)] or [0 HIDE LAND TRAILS(R)] as appropriate.
3. Referring to the table below, select the appropriate setting, then press the ENTER
MARK key.

trails.
