Water Type—because sound waves travel through fresh and salt 

water at different rates it is necessary to select the water type to 

ensure accurate readings on the unit.
Keel Offset—used to offset the surface reading for the depth of 

a keel. This makes it possible to measure depth from the bottom 

of your keel instead of from the transducer’s location. Enter a 

positive number to offset for a keel, or enter a negative number to 

compensate for a large vessel that can draw several feet of water. 

The Keel Offset reflects in the depth reading.
