Can someone give me an upbiased review or comparrison of the regs, especiallyt the new xstreams. Thanks.
Unbiased comments about gear from a diver? Doesn't happen!
Really tho'. The Poseidons are great regs from any point of view. So are the Apeks.
The Poseidons are great breathing regs, very over-engineered and solid performers. They are also very expensive, built differently than mainstream regs, and need a very good (properly trained) technician to service them. Access to parts may also be an issue. The side exhaust is very cool if you are a photographer (or so I am told....)
The Apeks are also top end regs. Very rugged and easy to maintain. With them being supported by Aqualung parts/technicans are much easier to come by now. A concern that I have heard is that the exhaust t on the new ATX line is too small for some people. Much more of a mainstream design.
Both sets of regs come from cold/deep water diving areas. Apeks was designed for the north sea and Poseidon are from Sweeden.
I don't think you can go wrong with either reg. They both do very well in US Navy tests (Slight lead to Poseidon)
A couple of things to think about is price and service. Around here a top end set of Poseidons will be 1.5 - 2 times more expensive than Apeks. Secondly, is there a good Poseidon technician in your area? Does your LDS stock Poseidon and/or Apeks parts?
Lastly.... have you tried them?
