Depth Sounder
The Depth Sounder displays the depth of
the water under the boat.
The depth can be displayed in feet, meters,
or fathoms. Audible and visual alarms can
be set to warn of shallow or deep water
conditions. A “keel offset” setting allows
the operator to adjust for the difference in
the location of the Depth Sounder
transducer compared to the deepest part of
the boat’s hull. The various settings are
accessed by pressing and holding the
“Mode” button while the Depth Sounder
is displayed
(see Figure 2,
