I have a Powerray and it has potential like the Qysea and they aren't suited to murky water. Propellers caught in algae while using Powerray on Lake Ontario, Lake Erie, Lake Binds and the Niagara River! Once under water in the dark, you lose your orientation. The cord also gets tangled. It has potential if you live where the water is clean. I have a YouTube video demonstrating the downsides of using these drones in muddy waters. I did drone beta testing for DJI and 3D Robotics when they first started making drones. Qysea should send me this device. Test in less clear waters. Not everyone lives in Hawaii or the tropics. Let's test it out here in New York and give us a review!
