Configuring My Boat

To configure settings for your boat, from the Home screen, select
Configure > My boat.
Keel Offset—offset the surface reading for the depth of a keel,
making it possible to measure depth from the bottom of the keel
instead of from the transducer location. Enter a positive number to
offset for a keel. Enter a negative number to compensate for a large
vessel that may draw several feet of water.
To adjust the Keel Offset:
1. From the Home screen, select
Offset.
2. Use the Rocker to enter the measured distance from the
transducer location to the water line or to the keel of the boat.
• If you are measuring down to the keel (transducer installed at
the water line), enter a (+) positive number. This shows the
depth at the bottom of the keel.
• If you are measuring up to the water line (transducer installed
on the bottom of the keel), enter a (-) negative number. This
shows the depth at the surface.
3. Select Done to accept the number.
