Range Projection function
The distance to a target located anywhere in the water column can be measured in two ways.
This can either be the horizontal distance to the target (
True ), or along the tilt angle ( Slant ).
The
Range Projection
function defines how this distance is measured.
How to open
This function is opened from the
Active
menu.
Description
Use the
Range Projection
function to control how the distance to a target is measured in a
horizontal view. This is a "selector" function.
