We have three situations:

1. Presence of external electric and magnetic fields at the site

2. Presence of magnetic materials at the field

3. Combination of 1 and 2 above

All these situations affect the compass calibration at the site. Please ask the manufacturer if it can handle all the above situations and tell us the net field direction change at the site with respect to the expected direction.
