This will orient the sensor coils for maximum signal when the magnetic field has low
inclination.

The G-856AX staff can be positioned horizontally or vertically when taking a
measurement. If the staff is held vertically then the sensor should be attached as show in
Figure 18. If, on the other hand, the staff is held horizontally during measurement, the
mounting points should be reversed. That is, the sensor should be attached at the saddle
mount in regions of high inclination and end mounted in low inclination regions.
Figure 18 is a map showing worldwide variation of the magnetic inclination. When used
in the green-shaded regions shown in Figure 20, the sensor’s cylindrical axis should be
oriented vertically. Outside of this green region the sensor should be mounted so that is
cylindrical axis is horizontal.
