Installation:
CAUTION: Disconnect the battery during
installation. Tighten nuts on the
backclamp only slightly more than you
can tighten with your fingers. Six inch-
pounds of torque are sufficient. Overtightening could result in damage to the
instrument and may void your warranty.
Mounting
1. Cut a 3-3/8” diameter hole in the dash
and mount the gauge with the backclamp
supplied.
The butt connectors have a heat activated
waterproofing. Once the butt connections
have been crimped, slowly apply heat with
a heat gun until you see sealant coming
out of the connector ends. It is
recommended to wrap the connections
together with electrical tape for further
protection.

Operation
Speedometer
The speedometer is a digital instrument
with the appearance of an analog
instrument. The speedometer is designed
to be operated from a “paddle wheel”
sensor. A microprocessor controlled
stepper motor moves the pointer to display
boat speed using a linear dial.
The microprocessor and stepper motor
provide excellent accuracy. Variations in
the operation of the “paddle wheel” sensor
are however fairly common. These
variations may be caused by the mounting
location of the “paddle wheel” on the hull,
which affects water flow characteristics, or
turbulence and air bubbles in the area of
the “paddle wheel”. Therefore, calibration
of the speedometer may be required and is
easily accomplished by using the Trip Log
display or the pointer.

button causes the display to change to the
“settings” sub menus (see Figure 2, page 6).
When the settings menus have been
selected, pressing the “Mode” button for a
short period of time causes the display to
cycle through the setting options. Within
each setting selection, pressing the
“Down” and “Up” buttons causes the
affected setting to change. The
microprocessor will automatically record
the new settings as you adjust them.

When in a setting menu, pressing and

Trip Log
The Trip Log is similar to the trip
odometer in an automobile. The distance
traveled, as recorded by the speedometer
“paddle wheel”, is displayed.
The Trip Log may be reset to zero, the
units of measure changed, or the
calibration adjusted using the sub menus.
Pressing and holding the “Mode” button
while the Trip Log is displayed will
change the display to the “settings” menu
(see Figure 2, page 6).
Trip Log “Settings” Menu
There are three items in the Trip Log
“Settings” Menu: Reset, Units, and
Calibration. Briefly pressing the “Mode”
button cycles through the menu items.
The microprocessor will automatically
record the new settings as you adjust
them.

Calibration
This menu item is used to simultaneously
adjust the calibration of the Speedometer
and the Trip Log. Two methods of
calibration are possible. These methods
will discussed in the Calibration Section.
Depth Sounder
The Depth Sounder displays the depth of
the water under the boat.
Pressing the “Up” and “Down” button
resets the Trip Log to zero.
Units
Pressing the “Up” or “Down” button
cycles the units of measurement for the
Trip Log between miles (MI) and nautical
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, page 6).

Depth Sounder “Settings” Menu
There are four items in the Depth Sounder
“Settings” Menu: Shallow Alarm, Deep
Alarm, Keel Offset, and Units. Briefly
pressing the “Mode” button cycles
through the menu items.
The microprocessor will automatically
record the new settings as you adjust
them.
Shallow Alarm
Pressing the “Up” or “Down” button
changes the setting for the Shallow Alarm.
Setting the Deep Alarm to zero turns off
the alarm.
Keel Offset
Pressing the “Up” or “Down” button
changes the setting for the Keel Offset.
Negative numbers indicate that the Depth
Sounder transducer is located ABOVE the
deepest part of the hull (typical). Allow
for worst case boat loading when
adjusting the Keel Offset as this setting
affects the Shallow Alarm.
Setting the Shallow Alarm to zero turns
off the alarm. To have this alarm indicate
the depth of water under the deepest part
of the hull, the Keel Offset must be
properly set.
Deep Alarm
Pressing the “Up” or “Down” button
changes the setting for the Deep Alarm.

Loss of Signal
When the Commander™ looses signal

the transducer, the LCD display will flash
the following;
Quickly press the “Mode” button three (3)
times to select and enter the Calibrate
“settings menu”.
There are two methods of calibration;
1) A GPS or radar gun can be used to
obtain a fixed speed. While holding the
boat at the selected speed press the
“Up” or “Down” buttons to adjust the
speedometer pointer reading to match the
GPS or radar gun indicated speed.
Calibration
Speedometer / Distance Traveled
Calibration is done in the Trip Log
“settings menu”. (See Figure 2)
Calibrate
Press the “Mode” button to display the
Trip Log.
2) The Trip Log can be set to zero and
then a course of known distance run, such
as between two buoys or by using a GPS.
At the end of the run access the
Calibration menu item.
Press the “Up” or “Down” buttons to
adjust the recorded Trip Log distance to
match the known distance. This will
calibrate both Trip Log and the
Speedometer.
