How to choose the start depth
This procedure explains how to control the vertical start
range (start depth) in the echogram. The start range is
controlled by the
Start Range
button on the
Main
menu.
Example 10
Start Range in a surface related echogram
In a surface echogram, set the
Start Range
value to 0 meters. This will
make the echogram start from the sea surface (provided that the transducer
offset has been defined). Set
Range
to the current depth plus 20 meters. The
echogram will now show the area from the sea surface and down to 20
meters “below” the bottom. The bottom contour is easily detected when
the depth changes.
Three different methods may be used.
