What to use as a Deco Reg?

[PfcAJ]

Get something good, you might find yourself spending a fair bit of time on it

I'm a fan of scubapro mk25s and mk11s, and g250s, s600s, and g250hps for 2nd stages. This deco reg might end up as a stage reg one day, or a deeper deco gas reg, keep that in mind.

My Dive Rite O2 reg was just sent to me. I was using a Poseidon but I switched that reg over to a single tank set up. I've yet to try the Dive Rite UW but my dive buddy has used one and says it's a great reg, especially considering the price. I can't wait to try it out, but considering the weather we're having right now it may not be too soon. Maybe the New Year's dive. Anyway I'd atleast consider it based on price alone.

Thanks for all the advice!!

My lds services almost all brands so I should be safe no matter what I buy. The regs that come o2 cleaned appeal to me initailly since i would not have to spend another $75 or so right after buying it.

I am probobly leaning to the dive rite reg since it seems well received by everyone...One thing I am thinking about is that I will be in the north atlantic most of the time so I want to make sure it will preform well in colder waters, what temps are you guys using the dive rite deco regs in?

I think the Dive Rite reg comes in a sealed version, which should be just fine in colder waters.

make sure you don't buy a reg for deco made with titanium though...

What's the issue with titanium? I don't have any titanium regs or have any plans on buying them, but I always wondered.

Titanium will burn - so if using a gas with a high O2 content (above 50%) where there a chance of a flash fire from adiabatic heating or just simply from the routing path of the gas which could then ignite the Titanium. Titanium as a powder or metal shavings is a fire hazard and, when heated in air, an explosion hazard. It is also used in fireworks to make bright sparkles.

There is also the misconception that "any regulator" can be used with high oxygen mixes. Unless the regulator is without any soft parts on the high pressure side, it is not truely O2 safe. Just swapping out the O-rings and lube is not sufficient for any breathing mix that gets closer to 99% O2.

The Poseidon Extream comes in an oxygen safe model and a Nitrox model that use a brass high pressure valve seat. The oxygen model is also design with a straight through flow path that removes the 90 deg. turns found in most SCUBA regulators that can add to gas heating from flow restriction. I don't know if the Dive Rite regulator is designed for 100% O2, but I suspect that if it is marked as such it is ok.

If you don't ever plan to deco on a mix over 50% than you will be fine with any regulator.

Also, the Poseidon's are designed for cold water diving without any additional parts or enviromental seals.

High oxygen percentages at high pressure will also cause titanium to oxidize which is a fancy word for rust.

Actually rust is a fancy word for iron oxides, usually red oxides. Alumina is the fancy word for aluminum oxide. Finally, titania is the fancy word for titanium oxide .
