I have tried several places. I have decades of experience at work in making electromagnetic field strength readings in the field using sensitive instrumentation, so I also have decades of experience choosing places which are least likely to be contaminated by existing magnetic or electrostatic fields.
Originally posted by kypfer For these purposes, I'd not rely on another GPS-based system for a reference.
Note that I said I checked it with my Pathfinder. I have decades of experience at work using magnetic compasses in the field. The Pathfinder is my favorite because it is designed for field use with topographic maps, which is what I was doing.

Originally posted by JensE Yes, but it contains nothing of significance which I did not find in the O-GPS2 manual. The same holds for the
O-GPS2 calibration instructions.

I know - unlike some people I thoroughly read manuals before attempting to use something. It is futile to try to use new, sophisticated, and expensive electronic instrumentation without first reading the manual, and it is wise to always have the manual on hand in the field when using the instrumentation. The O-GPS2 manual is not on the Ricoh site, so as soon as I opened the box I scanned the printed manual and put it on my phone to join the manuals for the K-70, all of my glass, and all of the other photographic items which I use in the field.
