Replacement second stage

victor · Jul 31, 2006

I have a US Divers micra and a Air2 which I have been very happy with.

I am thinking of changing both second stages, photography and tech diving are the driving force.

Are there any restrictions on what second stages I can connect to my first stage.

For example I believe I cannot use some poseidon second stages as they have a different interstage preasure.

Thanks

With the exception of older poseiden second stages, just about every first and second stage uses an intermediate pressure in a range of 120 to 145 psi. and can be mixed and matched - although that can make getting service interesting.

The Cyklon is the only Poseidon 2nd stage that likes a higher IP, usually 12 bar - 174 psi. It will work on lower pressure but just not up to its potential.
The Si Tech & Divex use an IP of 5 bar - about 74 psi.
