2.4 Finding out depth of targets in images (VRM operation)
VRM (Variable Range Marker) is a mobile marker to measure the depth of targets such as fish
schools, and indicates lines and depth values of the lines.
This can be also used as an indication of depth for casting net, etc.
VRM can display the second VRM set at a certain interval under the first VRM. This second
VRM follows the movement of the first one with the interval. This can be used as a measure
for depth of casting net.
There are two modes: to display a line on only one screen and to display one across the all
screens.
In the display on the whole screen mode, the same depth is indicated on all screens at
synchronized range/shift. Display and operation can be done on each screen at individual
range/shift.

VRM 1 line

<Example of display of VRM whole screen (All screens same range)>
