CHAPTER 6

Depth Finder/Sounder
In theory the depth gauge
picks up a bottom signal
sent through a transducer to
the helm gauge unit which
is converted to readings in
feet, meters, or fathoms and
displayed on the gauge. The
unit features shallow or
deep water alarms, both of
the audio and visual type,
and keel offset.
General Description.
The optional depth finder will display depths of 2-199 feet, 1-92 meters,
or 1-54 fathoms. To accommodate greater depths to be displayed in
the “ft” feet mode the depth sounder will automatically change to “F”
fathoms mode and continue to display depths to around 54 fathoms.
When the depth decreases below 200 feet the display will return to the
“ft” mode. Limits on depth will vary depending on transducers and
bottom conditions.
If the reading is less than 19.9 feet, meters, or fathoms, 1/10th
increments will be displayed. If the reading is more than 19.9 feet, all
readings will be in whole numbers.
The depth finder features an audible and LCD displayed depth alarm
with adjustable shallow and deep limits and a depth below keel offset
feature. These settings once made are stored in memory and will remain
even if the battery is not connected.
