Description
The Variable Depth Line can be added to your echogram to measure the depth. A
horizontal line with a depth readout is placed in the echogram. To change the depth,
select the line, keep the mouse button depressed, and move it up and down to place it
at the requested position. This function is typically used to measure the water depth,
the depth of a school, or even single fish.
To remove the Variable Depth Line, simply "switch it off".
This is a visual enhancement. It does not have any effect on the ES80 performance.
