Is this a cold water reg ?
Here's the catalog info from OMS directly.
The new OMS® R-250 (40% Nitrox ready) 2nd stage features an adjustment knob for increased air flow and a Venturi assist for excellent WOB (work of breathing). The 40% Nitrox ready first stage incorporates a balanced diaphragm design that offers high performance and is clearly the choice for cold and/or contaminated water.
I hope that helps.
i have been using the same octupus for couple of years now, and it is a good octopus. it worked well for me at temperatures just below 60 F or about 16 Celcius. Again, it is an octopus, so my usage was limited. overall, it has very smooth air flow with min. effort.
I've always used OMS,,,the bomb !!!..Why not ask,,OMS ???...My diving is in NY waters in summers,,,,bottom temps can be as low as middle 40's.. Nuff said !!!!...
I used it in 50 degree water for 3 hours.
Ellis I live in Texas and dont really do any cold water diving ,so I cant give you an answer to that, but I can say its been a good reg.

This regulator has no specific cold water rating, but I have used it on sub 40 degree water with no problems. In any cold water diving, the first stage being sealed is more critical.
OK Thank you. I am starting to upgrade for teck diving .
I have used this reg in 38 degree quarry water to 110 ft. depth without any freezing up or any other problems. Been diving with OMS for 4 years now... very satisfied with regs. Only brand I use for normal and tech diving.
OK Thank you that is what I needed to know
