    I'll be flying over a lot of water...isn't it true that catastrophic failure would be the only reason I could lose a drone? Never had ano issues with my P34k.

    I've heard that as long as you're not using VPS over water, you should be OK. VPS and water/other kinds of reflective surfaces don't seem to play well together.

    Yes...

    The aircraft tends to drift, as if in ATTI mode.

    So of I turn off the VPS, it will only rely on GPS? How do you turn them off?

    It's okay to use VPS over water. Just don't fly close to the surface of the water with it enabled. Also, you should refrain from pulling the left stick (throttle) to the full down position over water since it might engage Forced Landing mode. If that happens, you can cancel the landing.

    Wow, thanks for the heads up! Last question then, so what could happen if I fly too close to the water? Sorry I am still a rookie.

    If you're within range of the downward sensors, your Mavic might not hold its altitude as well. Also, it'll report an incorrect VPS altitude in DJI GO. Neither should cause a crash. Well, unless your Mavic is very close to the surface water and Forced Landing mode activates.

    In short, it's not a good idea to fly close to the surface of the water (or the ground). It's one of the biggest obstacles you'll encounter.

    Would you tell us please what you think is too close to water. How many feet off water might trigger the forced landing mode?
