I'm shooting a video for a friend who has a "chai" (where the magic happens, and grapes turn into wine). Each end of the storage area  can be opened and it's  lined by massive stainless steel tanks with a 2 metre walkway down the middle. I wanted to fly down the middle, out, and then circle the property.
Is there anything I can do/need to do to minimise the possibility of magnetic interference making the Mavic go haywire as it's in proximity of the tanks?
Thanks for any recommendations.

Actually, all good.  Got there before I could get any feedback and opted to just try going through, low and slow.  Worked fine without any changes.
