SCUBA dive with an APX8000? Yup! TEA Maritime OSK waterproof radio backpack.

Have you ever wanted to take a radio scuba diving… or am I the only one who thinks it would be awesome?
This is the TEA Maritime OSK system for waterproof communications. Obviously the radio can’t transmit or receive underwater - and nobody would be able to understand bubbles - but, this is a fantastic tool for super wet maritime operations.

I would be very curious to see how RF propagates underwater

[@AdventureCruiser]

Me too, any idea how a test could be structured?

[@ErikN1]

It pretty much does not. Divers use one of two systems for comms, a tether to the surface, or acoustic wave based communication equipment. Underwater drones usually use a tether for control.

Well I have a small generic GoPro like camera that has a wireless feature. The 2.4 GHz wifi propagates very poorly on it. Lose signal under an inch of water.
