Has anyone seen this? Is this true about the environementally sealed regs?

 

[otay!]

interesting read. it will be a while before i reach depths that will cause any of these issues, but good to know nonetheless.

To be honest that sounds like a big load of crap.
GUE did a bunch of dives on the Britannic in 1999 and knowing how anal they are about equipment I would almost bet money that they used sealed apex or scubapro first stages to 400fsw+ without a problem.

Edit: Check out this guy's photo gallery. I would NEVER dive (or trust) someone who's gear is so clustered up.

A marketing motive probably. If not why mention the brand?

Look at the pictures, look at the only Brand mentioned and given a thumbs up

He also posted this "beaut" of objective, balanced writing:

DIR - What it's not

He may have some great technical knowledge and a wealth of experience, but IMO it gets lost in the noise.

I bet he believes in the "vast right wing conspiracy" as well. I just can't take websites like this seriously. If you are going to put forth a criticism you should be able to clearly articulate your thinking and site sources. Not this "rant" of emotional and innacurate silliness.

Heck. I'm not even a DIR diver. Why am I defending them? Does this mean I'm going to Hell?

Somebody send me a cold beer if I do, ok...

I wonder if i set up a web site and post some good things about some brand.... maybe i will get some sponsorships too!

An n=1 (himself) is rather small to generate any statistical power to make such a statement... :11doh:

Yes it is true
Despite what others have said on this thread environementally sealed Regs will freeflow once a depth is reached where the LP from the first stage is high enough to overpower the balanced second stage Seat Spring, this is more of an issue where a Reg is 'overbalanced' such as some Apeks models

Horse puckie!
The guy has obviously never been diving in icing conditions.

Here's a little something I posted a while back, it explains why it is essential to use a sealed 1st stage when diving in icing conditions:

Regulator Freeze 101

Date: 2000-12-04


There's no set temperature where regulator freezes occur; the colder the water, the more likely it is to happen. Some manufacturers use 40° F (4° C) as an arbitrary number to define conditions where icing may possibly commence.
Both saltwater AND freshwater can get down to 28° F (-2.2° C) and not turn solid if kept moving, such as in a heavy surge or current.
The most common type of regulator freeze-up is the first stage. Unless you're using an environmentally sealed reg, there is water inside your first stage. That water freezes from the air absorbing heat upon expanding (compliments of a similar set of physical laws that make your referigerator work).
The result is overpressurization of the second stage, resulting in a free flow. Most folks THINK their second stage is frozen up, but it's actually the first stage that causes the second to malfunction.

Second stages do freeze up, tho mostly on the surface from breathing in them when air temp, wind chill, etc is below freezing. Simple solution: Don't stick the reg in your mouth until you're underwater.
The other type of second stage freeze is much more rare, in that the water temp almost always has to be below freezing & you have ice build up inside the regulator from breath condensation.
This can happen to even the BEST freeze-proof regulator if the conditions are right.
Hint... double hose regulators don't have this problem. To date, the most all-around freeze-proof reg is still the double hose.

Tip for folks using a separate bottle for drysuit inflation: Install a pop off (overpressure) valve on an LP port of the regulator. In the event of freezing, you won't have to worry about having a hose blow (or the valve on your suit explode).
