Steve, a rebreather for recreational diving? Why not?
OK, it is riskier on current models because they are not designed for recreational diving. But what about the new rebreather from Poseidon based on CIS Lunar technology and know-how? This rebreather was designed especially for recreational rebreathers. The first model will not allow deco and mixed gas diving. It will also have a depth limit.
We did a video interview at Boot Dusseldorf with Sverker Palmblad from Poseidon. You can find the interview at
Submerge Productions > Action! > Interviews
There will be an upgrade path to technical rebreather in future.
Then there is the Open Revolution rebreather technology. Based on what Alex has published there will be a model designed for recreational non-deco diving.
I believe there is a market for non-recreational rebreather diving.
