Aqualung reg

[rstofer]

Of course the manufacturer's recommendations are related to lawsuits. They don't want to have to defend themselves if a diver takes a warm water regulator beneath the ice cap.

And, yes, they did have to pick a number. Typically, that number is 50 deg F and that may be an industry defacto standard temperature even if there isn't a trade association behind it.

But the number is what it is: the limit below which the manufacturer is no longer willing to warrant the performance of their product.

So, why in the world would anybody else want to warrant it? Oh, wait! Nobody is saying "Yes, I personally guarantee that under every circumstance the regulator will function in cold water!" What they are really saying is "Go ahead and take the chance that the manufacturer is wrong but if the reg fails it is because your technique was deficient. Don't call me!"

Yes, the manufacturer is covering their ass. That's what they are supposed to do!

Is this a good setup and what water temperature would it be good for. I don't think I would go any colder that 45 +/-

Aqualung Titan LX first and second stage with Aqualung low profile octopus. No Gauges

It's 2 or 3 years old and looks to be in good shape (not abused)
What do you think it would be worth?

I tried post pictures but had no luck

Just got back from diving. I use two aqualungs on my kit. A legend and a titan (LX glacia). The water temps today were 37F and it's never frozen on me in that temperature, although I'm sure I could *make* it freeze if I caused it to free-flow.

I've also used it under ice and in very cold water, the coldest ever was a whopping 28F and it didn't freeze in that either.

I figure you'll be ok.

@Diver0001: To be fair, the Legend and Titan LX Glacia are designated as "cold water regs" by Aqualung. Both regs have environmentally dry-sealed kits installed on the first stages. The Titan LX Glacia has a few other features that make it more suitable for cold water diving (lipshield, extra built-in heat exchanger, etc.).

The Titan and Titan LX regs in question don't come in stock configuration with the dry seal kits installed. You have to "upgrade" to the kit. With the kit installed, they'd probably perform just about as well as your Titan LX Glacia.

Er... that's right. If the op is diving in 45F water then he would be well advised to get the "ice kit". As far as I know it's just some parts that can be retro-fitted onto any Titan.

Either way I think the Titan is a good regulator.

I think I found out where the magic 50 deg F comes from. Apparently, there is a European Norm m250:2000 that states that regulators intended for use below 50 deg F (the magic number) must be tested to function properly at 39 deg F.

See http://www.scubapro.com/media/1865151/scubapro_regulators-all-languages.pdf

See section 7.2 (pdf page 13, document page 11). I wonder about the wording of paragraph 1 where is says that ALL SP regs are certified for use in cold water in accordance with norm EN 250:2000. The part I wonder about is whether they mean all SP regulators are certified for use in cold water or that all determinations of capability are made using the standard and some regulators aren't certified (which seems more likely).

But now I have a different question so I'll start a new thread.

It seems that they're saying that all scubapro regulators conform to the EN250:2000 norm.

It seems that they're saying that all scubapro regulators conform to the EN250:2000 norm.

That's how I interpreted the language as well.

 

[rstofer]

There are other references in the document that support that interpretation: all SP regs are in compliance with the norm. However, that doesn't imply that all SP regs are suitable for cold water. Those that are suitable are tested in accordance with the norm.

At least that's the way I interpreted it.

Richard,

EVERY regulator sold in Europe must conform to the the EN 250:2000 norm.

thanks for all the info guys. I ended up getting a Mares Proton Ice from LP for a very good price. I read lots on the net and it sounds like it's good.

I look forward to trying it out in the pool in a couple of weeks.
