Steel connector on a magnetometer
Well, I discovered a few days ago that my yet-to-be-installed Garmin GMU-11 has a STEEL connector shell! It looked like steel, but I was confident that it HAD to be stainless or plated brass just like the flux gates I have dealt with from time to time over the decades. Nope. Steel.
Now I may have a problem. The connector may have retained a little bit of magnetism from the bit holder on the screwdriver that I touched it with. Time will tell.
Calibration may take care of any anomalies cause by the connector, but I think it might be a better idea to not have a piece of iron so close to the sensors.
