Requirement
If you want to apply an offset to your depth readings, you MUST set the correct offset
value, before relying on Depth data.
Therefore, before attempting to set a waterline or keel offset, find out the vertical
separation between the transducer and either the waterline or the bottom of the keel
on your vessel, as appropriate. See
Figure 2-1 .
