DIR Answer Required

On the other hand, maybe there are still a few self-taught cyber-DIR divers out there who don't yet realize that the DIR air limit is 1 ATM and that for anything deeper, Nitrox is usually a better choice.

Just for clarity, i'm assuming you meant 33' or the 2nd ATM. 33' ...... really?? Is that what DIR teaches for max recommended air depth?

No, 1 ATM is the surface.

DIR uses standard gases - and the standard gas for non-deco diving up to 100 feet is EAN32. Nitrox is better than air, so it is DIR. Settling for inferior solutions for $5/fill is not DIR.

LOL .... my mistake .... I had forgotten about the air is only for tires thing with DIR. Sorry ...

Using that convention, 1atm is 33', 2 ata is 33', 1 atm is sea level.

Make up your mind, Charlie

Anyhow, for the rigid thinkers who couldn't figure out what I meant, I edited my posts to ata instead of atm

Perhaps someone can fill us in as to whether or not the increased risk of air in a pool is acceptable.

I use tire gas for pool sessions. For me, the "increased risk" is acceptible

I use tire gas for 12' PSD dives as well.... but there's nothing DIR about those either

I'd correct my typo, but Jonnythan declared my post a troll and deleted my response to him.

I guess TCDiver and I are just a "rigid thinkers" for wanting to clarify whether you mean 0' or 33'.
I won't take that as a personal attack.

...my typo...

I know - that's why I put the winkie smilie after my comment

 

[Snowbear]

I won't take that as a personal attack.

It wasn't meant as such... it was twist on the comments of some that call DIR folks rigid thinkers and inflexible and blah blah blah .....

Just trying to lighten things up a bit

What you don't see is the PM exchange I've had with Jonnythan, asking that he forward my original post to someone else rather than him deleting a post that quoted him and was correcting his use of atm and ata.

It put me in a bit of bad humor. Sorry.

A good cleanup would be to delete Jonnythan's post of "No, 1ATM is the surface"; delete TCDIver's post since you clarified it with the editing of your post, and delete all of my post from today out of this thread.

From both of my DIR-F courses and my RecTriox course, the standard recreational gasses were as follows:

Air - 60'
32% - 60' to 100'
30/30 - 80' to 120'

Obviously 30/30 to those depths doesn't meet the Standards as defined by GUE (http://www.gue.com/Training/Standards/index.html), and I've heard from others that Bob Sherwood is now teaching that 30/30 is good to 100'. I've heard nothing official from GUE to back this up though, and have sent off messages to a few GUE instructors to find out when GUE dropped Air from their standard gasses.

IMO, you have a few people voicing either their personal opinion or the opinions of their instructors / buddies.

Air wasn't even mentioned in my Fundies class.
