Using VRM
The VRM (variable range marker) key is used on the Fishfinder to
determine the depth and distance-behind-boat of an object on the
display. The VRM function is available on the scrolling Fishfinder
display, bottom lock and zoom windows.
A VRM is displayed as a cross hair with height and width of the
display window. The center of the crosshair is the reference for which
depth and distance-behind-boat are displayed. You can use the cursor
to move the VRM over a particular object.
Depth is displayed (in system units) on the VRM. In the scrolling
Fishfinder and Zoom windows, depth is measured from the surface
down. In the Bottom Lock window, depth is measured from the
bottom up.
