Looks like Russia made one during the Cold War for frogmen firefights (<-wild) At a depth of 15 ft, its effective range was 909 ft!! The deeper you go the worse it gets though, and it totally sucks on land too
Every source I can find mentions maximum effective range at 15ft to be ~98 feet, not 909. So that zero in the middle is probably a typo, if I had to guess.
Whaaat I didn’t know they made those!
