Guys, I posted this over on the DJI forum, and everyone said risky but might be worth it for the shots you can get, but any additional tips would be useful. Cheers. I am headed off on a liveaboard diving around the Maldives for 8 days and I am pretty stoked to be taking along my P3. I am concerned about doing a compass calibration on a boat which is made almost exclusively of metal. We will also be travelling quite long distances each day/night as we dive without heading to land, so I am not sure how I can calibrate/fly safely. Any tips would be greatly appreciated.
