just finished an ice diving (recreational) cert......we normally dive scubapro 600`s.....without an exception, almost ALL froze up. The dive operation up at Lake George uses Sherwood Blizzards. If you`d like me to put you in touch with him, I can. He was an awesome instructor and runs recoveries, etc. up there.....

Sherwood Blizzards are made for cold water diving. The Poseidon is a very good reg for cold water but you will pay a pretty penny for them and they have lots of parts so will cost you to service as well.

Poseidon all the way! I train a lot of rescue squads and they all choose to go Poseidon as well. In fact I was training 2 weeks ago in sub 30 degree water. My breath was freezing on exhalation and making pinging sounds inside the 2nd stage -- I was even able to get some frozen pellets back into my mouth on inhalation (I had just finished drinking A LOT and my breath was extremely wet)... Not one sign of freeze up or freeflow! I do use environmental kits when training in overhead super cold environments -- but this was a shallow training dive that I didn`t even use the environmental kit on! If I can help you with regulator selection or any other info -- please shoot me a message.... All the best- -- J

Hey Nathan, Never dove a poseidon, but parts kits are costly, and tough to find reps to service them. I use an assortment of Scubapro First and second stages. I use a Mk 17 (environmentally sealed balanced diaphram), and love it (forget if you use AGA`s or other FFM`s, or second stages). I have a G250HP, but would definately look at the new G250 V(intage)with a metal barrel for heat transfer compared to the plastic of the HP. Seperate PM sent on pre and post dive procedures to minimize freeze-ups. All the Best, John

I wood look at sherwood, They do have the blizzard which my NAPD instructor uses north of the artic cycle so I know it works. I have had my brut (do not rmeber which model) in 20 f water and it was fine. If you are doing PSD then the sherwood also has you covered from contamination. it is a dry bleed system so no bad stuff gets in, it is why I bought sherwood for the Sheriff`s Dept Dive team when I ran it. Hope this helps
