Calibrate Speed
This only appears if you are using a speed-capable transducer.
Calibration is required to ensure that the speed displayed on your
unit is accurate. Use the boat’s speedometer, a stopwatch, or a GPS
to determine your speed. If using a stopwatch, measure the distance
that the boat travels in a period of time (distance / time = speed). It
is recommended that the calibration take place in water having little
or no current.
To calibrate the speed:
1. Highlight Calibrate Speed, and press the ENTER key.
2. Bring the boat to cruising speed, note the top speed, and
stop the boat.
3. With OK selected, press the ENTER key.
4. Using the up or down Arrow key, set the maximum speed
and press the ENTER key.
NOTE: If the boat is not moving fast enough or the speed sensor
is not registering a speed, you will see Speed Too Low displayed
in the selection box. With OK highlighted, press ENTER and
check that the speed sensor wheel is moving or safely increase
boat speed. If there is a problem with the speed sensor/unit,
check the cable connections.
