well what have we got here now?
Aha a compass on a stationary stand. Not so new or ground breaking news...!
But...
did you firstly prior to taking any compass bearings calibrate the compass...??
and then did you..calibrate the person(s), taking the bearing, ..eyes...?

All Qualified Surveyors will always calibrate the compass
and their eyes prior to any work with a sighting compass...
so...
Next...?
