Review on Chasing F1 Underwater Drone: Portable Submersible with 1080P Full HD Camera, Night Infrared Scene, 96 FT Depth & Temperature Detection, Real-time Display, Underwater Camcorders for Ice Fishing by Dewitt Bhattacharya

Just unpacked today. (I also have Dora) Setup took about 10 minutes physically and 10 minutes for the app. I downloaded it onto the Galaxy S7 from Google Play and went to the kids' pool (36 inches deep and 10 feet in diameter) to try it out. No problem for a short trial lesson. After starting I had to update the firmware. A little getting used to and being able to see the drone and adjust movements accordingly helped me. First impressions I need a bigger screen so I'll try connecting to a tablet instead of a phone and I'll have to look at the GPS capabilities. Will be tested in a lake or pond this weekend Warning I don't know if you can change metric measurements to imperial will have to check that out.
