72MHz is not good because it is reserved for aircraft.
75MHz is what most use here in the USA. Reserved for surface use.
Submarines are considered surface use.
2.4GHz does not work because the signal does not penetrate the water more than a few inches if at all. It's reflected.
The issue is that the 75MHz & 72MHz radios and receivers are being phased out here for the 2.4GHz. We can still get 75MHz receivers made in Canada. New transmitters are becoming harder to find.

WFly still makes them & you'll find several in the States selling with Sub Driver offering the best price. I have one & can recommend the brand.
Here's a link to the WFT08 manual:

I use an old Futaba 8u. The great thing about it was that it was cheap because it was "old" technology, and it allows the usage of rf modules. This allows the entire rf section to be removed and replaced with 72MHz, 75MHz, or your favorite 2.4GHz flavor.
On a side note, it is sad to me that so many of these radios cost so much. There really is not all that much that goes into them. The programming is not terribly complicated. I know that there are some open source efforts out there as well.
