22 Pathfinder Smart Heading System - Owner’s Handbook

3 Calibration

4. When compass linearisation is complete, the Pathfinder Plus unit will

beep and briefly display the following pop-up message.

5. You will then see the ALIGNING HEADING box, showing the corrected

deviation.

Note: If the deviation figure exceeds 15°, the fluxgate compass is being

affected by ferrous objects on your boat. Move the fluxgate compass to a

better location. Higher deviation figures are acceptable on steel boats.

Step 3: Align the heading

Align to COG (if available)

Note: If COG is not available, proceed to ‘Fine-tune the alignment’.

1. Manually steer the boat on a steady course at a speed which enables

you to hold that course.

2. If you have a GPS connected to your Pathfinder Plus:

• hold the boat on a straight course and increase the boat speed to

more than 3 knots, then wait about 30 seconds for COG to

stabilize on an accurate course
