hi, please understand, we make the goggles ,not hobbycity, and we don't know if their goggles even have acceleromoter and compass inside, coz we did sell about 30 pieces to a unnamed company long time ago. and the goggles actually had 3 version,
version 1: only magnetic headtrack, not moving accurately,pass
version 2: has accelerometer and magnetic compass, moving weird, not correct the heading correctly, pass
version 3: the current FOXTECH version, has gyro, accelerometer and magnetic compass, so that's why it can correct the drift
so i can't guarantee the goggles they sell is 100% same to ours.
