2.3 Installing the fluxgate compass
Fluxgate compass - description and dimensions
The fluxgate compass contains a self-levelling mechanism. This enables
the compass to provide accurate readings with pitch and roll movements
up to +/- 35°.
Figure 2-1: Fluxgate compass dimensions
Note: The rattle that the fluxgate compass makes when shaken is normal.
It is caused by the pendulum weight hitting a buffer inside of the case.
Select the location
The compass is primarily designed for mounting below deck on a
vertical bulkhead.
Note: On steel boats the Fluxgate Compass should be mounted above
deck (see page 13).
Standard location
To achieve the best performance from the compass, mount it:
• as near as possible to the boat’s pitch and roll center to minimize
compass disturbance (as shown in the shaded areas in Figure 2-2)
• at least 0.8 m (2 ft 6 in) away from the boat’s steering compass to
prevent deviation of either compass
• away from the front third of the boat (otherwise shock motion will
affect compass performance)
• away from potential sources of magnetic interference, such as:
motors, drive units, loudspeakers, alternators/starters, electric cables,
large ferrous objects (such as engines, ballast, keel, gas bottles and
tool boxes)
