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.
