Control Bar on the screen as the chart scrolls. You can see the

matching the sensitivity to rapidly changing water conditions.

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
displayed by the digital depth, chart depth scale, chart cursor or fish
symbols 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
actual depth is 31 feet.
On sailboats or other large vessels with deep drafts, the distance
between the transducer installation and the keel or lower engine unit
can be several feet. In those cases, an inexact depth reading could
result in grounding or striking underwater structure. The Keel Offset
