Boat speed
Speed calibration is necessary to compensate for hull shape and paddlewheel location
on your boat. For accurate speed and log readings, it is essential that the paddlewheel is
calibrated. Boat speed values can be shown in knots, kph or mph. Your preferred unit of
measurement can be set in the units page of the setup menu.
Auto - Calibration via reference to GPS SOG value
This is an AutoCal facility that uses speed over ground (SOG) from your GPS and compares the
average of SOG against the average boat speed from the speed sensor for the duration of the
calibration run.
¼ Note: This calibration should be made in calm sea with no effect from wind or tidal current.
1. Bring the boat up to cruising speed (above 5 knots)
2. Select Auto on the Boat speed calibration page
3. When the calibration is completed the Boat speed calibration scale will show the adjusted
percentage value of the boat speed.
USE SOG as boat speed
If boat speed is not available from a paddle wheel sensor it is possible to use speed over
ground from a GPS. SOG will be displayed as boat speed and used in the true wind
calculations and the speed log.
