Keel Offset
A depth transducer measures depths below where
the transducer is mounted on the boat, usually the
bottom of the boat. The Instrument calculates the
depths to display by adding the keel offset to all
measured depths.
A Have a zero keel offset to display depths
below the transducer.
B Enter a positive keel offset to increase the
displayed depth. For example to display the
total depths below the surface, enter the
depth of the transducer below the surface.
C Enter a negative keel offset to decrease the
displayed depth. For example, to display the
depths of clear water below the boat, enter
minus the depth of the deepest part of the
boat below the transducer.
