CHAPTER 6
6-62
In theory the depth fi nder 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 depth fi nder 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 fi nder 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. Store vessel with bow slightly
tilted for proper drainage.
