Depth offset
Depths are measured from the transducer to the sea bed. However, you can use
the depth offset screen to apply offsets to this distance, so that the displayed
depth reading represents either the depth from the keel or the depth from the
water line (
W/L
). In order to do this, you need to know the vertical separation
between the transducer position and:
• The bottom of the keel. This requires a negative offset.
• The water line. This requires a positive offset.
