Gym equipment gannets field?

[Eduardo Bilbao]

I have to shoot for a fitness center here in my city, and after the flight to show my client the app gave me a compass error.

Do you guys think that the weight lifting equipment metal is affecting it?

I've had compass errors when I was too close to metal (like trying to take off from my car roof) or too close to a metal manhole cover. Usually if I pickup and move away from the metal object the error goes away without having to re-calibrate.

Yes, I've had the car effect the MOD values. I did my "reference" compass calibration in the middle of a soccer field, and had good values for all previous flights. I travelled about 300 miles south, set up the Inspire on a camp table next to the car, checked MOD values which were quite low. Moved the Inspire about 30 feet away from the car, and the values went right back to within good range right around 1500 without recalibration.
