Wake tower magnetic??

I had a few extra hours to spare today so I went to the lake with my new drone for the first time. I was able to get the drone to take off and I put it in follow me mode roughly 30 feet from the boat and 30 feet up. Upon planing the boat the drone sped up to follow and worked great for about 5 seconds. It then stopped moving and the error message flashed "Magnetic Interference. Recalibrate drone compass. Drone will hover in place when you exit this message." I turned around, clicked okay, and brought the drone back to the boat safely with no issues. Upon getting it back in the boat I was unable to re-calibrate the compass, it kept saying "the magnetic interference is too great move away from large metal objects."

Once I got back to the marina and on land I flew the drone around with no issues for the remaining battery life. Has anyone had a similar issue? Is it only possible to do land based operation? Its a Phantom3 Standard and the boat isn't a Pavati.

Was part of a photo shoot a couple seasons ago and the operator launched and landed his drone with the boat in motion. Flew is all around filming the boat, wake boarder and some surfing. No issues due to the boat, tower or 4 tower speakers. Also most towers are either aluminum or stainless or a mix of both, neither are magnetic.

So are the tower cans. All will be aluminum or stainless.

My cans are actually plastic but the speakers is a good idea. I assumed it was either the engine or the tower because it said "move away from large metal objects" and I didn't even think in terms of magnetized material- but even in the bow area I could not get it to work.

Doesn't matter what the cans are; every speaker in the world has a magnet - tower speakers typically larger than most.

I would bet it's the tower speakers that are creating the interference.

Calibrate drone on the dock maybe before leaving?

I was replying to jgraham mentioning all cans are metal. I would suspect even after calibration once I get it out on the water it would still have issues flying but I suppose its worth a shot.

Yes, I didn't think about the speaker magnets...

After doing some more digging if I'm unable to calibrate it my only option is to either do land baser operations or fly it in something called Atti mode which disables the GPS and Compass. The only problem there is that you only have an altimeter, you lose all of the follow me or point of interest features, as well as the go home feature, and this would require it to be manually flown throughout, which i imagine would make chasing a boat smoothly incredibly difficult.
