Compass calibration

The compass calibration procedures are:
• Swinging the compass.
• Aligning the compass.
Swinging the compass
The magnetic deviation correction procedure (commonly called "swinging the

in circles (keeping the boat's speed below

• Take at least 2 minutes to complete each

• Complete at least two circles.

show a Slow down message. If this occurs,
apply less helm to turn in a larger circle.
