Submerging most regular drones in water probably wouldn’t be the best idea. Waterproof Lily drone has failed, and I hope you didn’t order one as there were some problems with refunds. So, if you’re still looking for a drone to fly over glistening lakes, film water activities or even submerge it in water, Swellpro Drones can be a good solution.
This video from Dustin Dunnill demonstrates how the drone works both in the air and underwater. You can get it in and out of the ocean like a teabag, and it rises up and flies with no trouble.
