The field in a house is also very distorted as most houses have steel in the walls, and small movements in position will greatly affect the field, so if you calibrate in a house be careful to rotate the sensors but not move them to different locations in the house.. You will have to recalibrate anyway on the boat to fix the bias.
Thanks, our house is mostly concrete / brick, I was calibrating on a desk chair that turns around its own axis. But, better to calibrate on the boat I guess.
