The only noise you hear is that of your own breathing and of the fish dancing around you. If diving was peaceful before, it is beyond blissful now.
Poseidon has been, and still is a pioneer in the rebreather industry. Their SE7EN+ with Solid State O2 sensor compatibility has set a new standard for safety and technology.
Available in three different packages, the SE7EN+ can be anything from a recreational to a deep and explorational rebreather. Which ever one you choose, diving will never be the same for you again.
