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.
