Heres an example of what you can build (for a fraction of what they sell for). Ten years ago ( pre quad copter junk) .This was Israels 'top shelf' drone. I was so impressed with the flight times of it.That I decided to build one from scratch...... They spent 1/4 Million per copy.I, over the entire winter built "the exact one " for under $500.00 . Flight time ? Over 3 hrs View attachment 1618809
Maiden launch.View attachment 1618810
Maiden flight. IF I can do it Anyone can. Land ,air ,sea no difference .Especially w/the building materials & info available today .
And, the A.U.W. of mine (at the same size as theirs) came in at 1/2 the weight @ 6 pounds.
In conclusion .If you want a "underwater drone" ....build one....

OK. I took your advice.
