MAK52580:Poseidon's are OK, but they require an environmental seal on them. I dive a SP MK25/S600 and have never had any problems with it. I dove it to 34 degrees and it breathed like a charm. Just make sure not to breathe it on the surface before you descend to avoid possible condensation build-up and you will be fine. Although this is not just a SP recommendation. You shouldn't breathe ANY reg on the surface prior to a cold water dive.
I love my reg, and just bought an identical second for my doubles.
Only time I needed an enviornmental seal on my poseiden was for shallow Ice dive. Not for in the water but out of the water.
In water temps were 34-36 deg, and reg performed flawlessly. The problem was on surface water in the diaprham chamber froze up in the 15 deg air (w/-17 deg or so wind chill)
