Octopus for cold water?

[Baastrand]

Hi

I am planning on buying Aqua Lung Legend LX Supreme for first and second stage because i want to use it in cold water. In the offer I have got it goes with Aqua Lung Titan otopus which is not for cold water like the rest. I have been told that it doesnt matter when its only the otopus.

Is this true?

Thanks

Not a cold water diver but logically..... if you are actually diving in water where freeze-up is a possibility, I'd want every 2nd stage to be cold water capable...

I guess I'd ask the person who told you it didn't matter if the octo was designed for cold water use if they'd be comfortable using the octo as their primary 2nd stage on a cold water dive...

Is the water temperature where you plan to dive cold enough to cause 1st or 2nd stage freeze-up?

Best wishes.

Having done ice diving... you WANT an octo rated for the cold water.

I went through the same issue. I had an aqualung Glacia first and second stage (was a good deal at the LDS), and was looking for an octo. Like the above advice, I decided if my GLACIA freezes over, I would want my octo to be just as capable if not more so than my primary. I ended up going for an Apeks XTX40, and the Glacia octo probably woulda been just as good. Really, you just dropped $500+ on a primary, whats another $250 for an octo? 6 months down the road, you won't miss that extra $100, but you will kinda be kicking yourself when you look at your reg and see such a nice primary and such a not-so-nice octo.

Full disclosure, i'm still very new to diving, and have 0 ice dives (or even 'cold water' dives) under my belt. So yea.

The biggest problems with regulator freezing are in first stages where the greatest refrigeration effect due to expanding gas occurs. The solution is isolating the ambient pressure sensing components with a diaphragm or fluid with a much lower freeze temperature.

There are some flow characteristics on second stages to minimize the formation of ice, but the problem is far less frequent — especially on a regulator that is not used since there is no expanding gas to cool the metal parts lower than the water temperature. In my experience, second stage freezing is the biggest problem when you are at the surface where air temperatures may be well below freezing and moisture from you expirations caused momentary sticking. That sticking always cleared up once the regulator housing and tanks were "warmed" after hitting the water.

when your buddy's reg starts to free flow,having a safe second rated for cold water
is a big plus!
..while you're hoping yours doesn't free flow,while his thaws out!
personally,i'd spend the xtra $
or make it more exciting and wonder if ya should have
either way
have fun

My question would be why a cold water promoted reg would be permitted by the manufacturer to be married by a dealer to one that is not?
