You need an accurate way of knowing boat
speed, such as another boat with a calibrated
paddlewheel sensor or a GPS receiver.
For accurate calibration:
• The speed from another paddlewheel
sensor should be between 5 and 20 knots.
• Conditions should be calm, with little
current (best at high or low tide).
To calibrate:
1 Travel at a constant, known speed.
Select the SPEED setup menu, then select
2
CAL.S, the boat speed.

Then press ENT to save the correct value
(otherwise press ESC to exit).
Note:
After you press ENT, it does not matter if the
boat's speed changes.
