•If you want to display the depth reading from the transducer, set a value of 0.0.
•If you want to apply a water line offset, adjust the displayed reading until the appropriate positive offset value is shown.
•If you want to apply a keel offset, adjust the displayed reading until the appropriate negative offset value is shown.
