Transducer Configuration
Setting the Keel Offset
The keel offset compensates for 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. You can enter a negative number to compensate for a large vessel that
may draw several feet of water.
1. Complete an action, based on the location of the transducer:
If the transducer is installed at the water line, measure the distance from the transducer
location to the keel of the boat. Enter this value in step 3 as a positive number.
If the transducer is installed at the bottom of the keel, measure the distance from the
transducer to the water line. Enter this value in step 3 as a negative number.
