Set Keel Offset

This unit measures water depth from the face of the transducer. Since the transducer is installed below the water surface, the distance dis- played by the digital depth, chart depth scale, chart cursor or fish sym- bols is not the exact water depth. If the transducer is 1 foot below the surface, and the screen shows the water depth as 30 feet, then the ac- tual depth is 31 feet. On sailboats or other large vessels with deep drafts, the distance between the transducer installation and the keel or
