Regulator Question

[Comstockfire]

Do regulators designed for cold water perform well in warmer water?

I am putting together my equipment and am wondering if I need 2 regs, one for Michigan / Great Lakes diving and one for Caribbean diving.

This is the reg I am looking at: Mares V32 Proton Ice Extreme discounts on sale Mares

This may be a question but I want to be sure.

Yes.

Sealed cold water regs are also generally easier to rinse as no water gets inside the ambient pressure area of the reg.

There are however differences in design that you might want to consider.

For example the Scubapro Mk 11 (unsealed) and and Mk17 (sealed) share the same basic design, but the Mk 17 uses a thinner diaphragm and an extra washer and that comnbination provides a bit more flow rate over the Mk 11.

The Mk 17 will however also not suffer any loss of performance if the outer diaphram fails, where some other brands of sealed regulators will lose up to 20% of their performance due to how the sealed portion of the reg transfers pressure.

You will have no problems with that reg in cold or warm water. FWIW, my primary reg for many years was a Sherwood Blizzard that has not only seen it's share of cold Great Lakes diving, but has also been to the Red Sea several times.

Enjoy!

It is interesting that you bring up the Sherwood Blizzard. The blizzard was a winner in cold water from the beginning but did not sell well to warm water divers because of its name. It was rebranded as the Oasis for sale to those who wanted to dive the tropics. If you read the marketing literature, you would think the Blizzzard and the Oasis are two different regulators regulators, but if you look at the service sheets you will note that all the parts, except for the logo, are the same.

<heheheh> Yes, I was aware of that captndale after the first time I went looking for an HP seat for my Blizzard. However, that being said, doesn't the Blizzard have an additional heat sink unit in the 2nd stage?

I use the M17 for both with no problems. Love it.

It's been awhile since I have serviced Sherwood regs, but the second stage heat sinks (two of them in both the Oasis and Blizzard) are what captures/condenses and recyles the moisture in an Oasis.

I.e. "cold water" second stages with more metal and better heat transfer also condense more water and do not create as much dry mouth due to the effects of the improved heat transfer.

So in those two second stages what does differ is the logo.

Thanks for all the info. It seems if I get a higher end cold reg, I'll be good to go.

Actually there is a small difference. The pieces themselves are the same, but the Blizzard uses a teflon coated Lever and Screw in the 2nd Stage to help prevent the buildup of frost and/or ice in the cold environment. Other than that, the 2 regulators are identical.
