What is best reg. for not getting dry mouth?

[BeaverDiver1]

The Oasis is a good reg, but the Blizzard has the same moisture retention properties as the Oasis, but the design has been tweaked specifically for Cold Water

Personally I will stick to my Conshelf XIV, the metal body does a great job of keeping the moisture in

I had the Oasis before my wife started diving and ended up with my first kit as hers.
It does live up to it's advertizing as relieving dry mouth and is otherwise a fine reg.
As others have stated the Blizzard is essentially the same but design and rated as a cold water reg. Also in the Sherwood line is the Maximus which is also said to be a excellent cold water performer with adjustability and the internal fins that reduce dry mouth.
I myself now dive a Oceanic Delta 4 FDX10 I have not notice a dry mouth problem using it. It tends to be a wetter reg and is a top cold water performer with adjustabilty.

A metal cased second stage like the R109 is ideal. Dry mouth was basically invented with the advent of plastic cased regs.

Sherwood's metal inserts were a response to dry mouth that occurs in all plastic regs, but you get the same effect with any second stag with a metal air barrel like the original G250 or current G250V, Aqualung LX, etc.

Do not under any circumstances use a biofilter in cold water diving. Introducing moisture insiede a system with air potentially flowing at below freezing temps has bad written all over it.

Good point!

I'm cold-natured, and have absolutely no intention of doing any ice diving... ever... So, I've never considered the mechanics of a bio-filter in sub-freezing temps... In fact I've never considered the mechanics of gas temperature at all in these conditions.

Out of curiosity (and forgive the minor hijack), does anyone know at what temperature the gas is delivered to your 2nd stage (and ultimately your lungs) during an ice dive, and is there a danger of actually freezing or spasming your respiratory system?

The reg that is the best at giving me a very dry mouth is a plastic body Kirby Morgan Superflow.
The metal version of the same reg is the exact opposite...it's my reg of choice especially on very long dives.
The KM is the driest breathing reg I have ever used.

wow i didn't think this post would get so much response. I was looking at the aqualung Legend Glacia but there is no articles on this regulator and i don't want dry mouth anymore. Nobody talks about this regulator at all. After all in lake erie in the middle of winter is very cold, water temp. is about 33-34. So i need a tested cold water regulator.

If memory serves me correctly (& I could be mistaken), that it exits the tank into the 1st stage at just a little above freezing to begin with. In warm waters the heat transfer of the water will warm it almost immediately. I dive in quarries mostly & below 50ft or so it's a "refreshingly cool" 42 degrees or so year round. At those temps or colder there is a very real possibility of 1st stage freeze up & free flow because there is not nearly the warmth to warm the air as it moves through the 1st stage & hose. In fact, it is a rather common occurrence. I've not yet (knocking on wood) had it happen to me, but I keep in mind that can happen. One reason I typically dive doubles when going deep. If I have a freeze up, then I have only to switch to my secondary (a separate regulator) & shut down my primary for a few moments to let it thaw out, turn it back on & continue on. I have never heard of freezing or spasming of the respiratory system from cold air, but not saying it couldn't happen either. To breathe air at those temps is like breathing it on a cold winter's day. It can be a little irritating to the throat, but by then the air is usually warmed up sufficiently for the lungs. If a diver has lungs that are that sensitive to cold air, then there must be a respiratory problem already in place & I would question whether they should be diving at all, But then I'm not a Dr. & that's not my call. Other than it being a little colder, I've not really noticed any difference between breathing air on a warm water vs. cold water dive. I can't say though, that I've ever dove in waters below 39- 40 degrees & never done any ice diving (just hasn't been cold enough, long enough here for that to happen).

I remember doing a 3 mile run for an annual USMC physical fitness test in -13 F weather. After surviving that I don't worry about cold air from the reg when ice diving.

Another sherwood vote here. The magnum has the fins as well.

Uh, no. The Magnum second stage does not have heat transfer fins.
