Greetings, I am sorry to be late to the party. I have been expecting some speculation regarding GUE’s CCR evaluations and I appreciate reading some of your ideas. Contrary to the insinuation of some, my personal interest in CCR is not financially inspired. I have been interested in CCR as...

Hey Gang, I hate to beat a dead horse but a discussion on the GUE forum left me feeling I had not properly outlined my thoughts on the whole PO2/MOD issues. I have seen this question a few times and I feel a strong focus on PO2 obscures our intent in creating standard gases with fixed MOD...

Thanks Nick<g>. You have it correct. 12/70 was meant to replace 10/70 and we would adjust O2 with deeper/longer dives in what is essentially a Heliox mix. Deep or long dives require more tinkering sometimes but by then someone should be pretty comfortable in this arena. RJack, I am sure you are...

Thanks Nick. I am happy to participate. I think your community is handling this very sensibly by evaluating various positions, trying on different perspectives and assembling an opinion. I am sorry if it appeared I was discouraging discussion. The exchange of information is almost always useful...

A subject near and dear to my own heart;-). I have invested considerable energy into this subject and long considered it the most nebulous and challenging risk we face in very long exposures at depth. What we know (or don’t know) about CNS toxicity is startling. What we don’t know about CNS...

Sorry if I appear "upset". It is merely a sense of frustration over tinkering with long standing and successful standards where no benefit is gained but confusion and risk are created. It reminds me of the days when we had to argue about Nitrox banners on tanks. I can't imagine having a bunch of...

Greetings all, My overview of these posts leave me feeling you guys have covered the issues well. I am pleased to see people promoting the benefit of maintaining a standard as I find that the most compelling benefit within DIR. I have always felt people let themselves get too worked up about...

Wakulla is finally clearing and I am heading out the door for a weekend of diving but when I return it would be nice to hear your rationale for such a statement. A RECREATIONAL diver doing min deco doesn't NEED any deco gas for this sort of dive. However, adding a small bottle enhances deco...

[ mod: copied this over from the other thread in the DIR forum on the same subject -- Lamont ] Greetings, This thread came to my attention. It is unfortunate we struggle to find time to contribute on these forums because in general they provide a potentially great source of information. I am in...

Greetings, This thread came to my attention. It is unfortunate we struggle to find time to contribute on these forums because in general they provide a potentially great source of information. I am in the midst of travel (wifi in planes is a great advent) and likely not able to do much back and...

Hello all, My apologies for this delay. It is difficult to wade through much of this and nearly impossible to speak to all the various points. I will try to account for some broad responses here and then reply to the issues of "Hogartian" in a separate post. For those that are disinterested in...

Part 1 of 3 Hello Everyone, I know that many of you decided long ago how you felt about DIR, Halcyon, and GUE. However, some of you are still trying to evaluate these groups and how they fit into your future diving plans. Over the years I have watched individuals intentionally...

I just wanted to close out my involvement in this thread with a quick note and then a post on the promised topics of DIR, GUE, and Halcyon. As I anticipated there is a substantial range of back and forth on the several contentious issues presented here; this is particularly true when...

I really do want to thank all of you for your perspectives. I find some of this extremely useful toward improving our offerings as a company. I am appalled by the service I get from nearly every company with which I interact. I can speak personally to how surprisingly difficult it is to manage...

Genesis, I honestly feel that you are being unfair with us but, as I said, appreciate your perspective. However, you represented to the group that it would be an "understatement" to say that I (jarrod) was hostile. Upon being pushed, you back down to Charlie who I am nearly certain did not...

Thanks all. I am very appreciative of your notes. I am going to finish up a historical perspective note today if time allows because I feel that many really just don't understand the evolution of DIR, Halcyon, or GUE. More info about the inflator and wing will be available shortly. I have...

Thank you all for your comments. I appreciate your welcoming me into your community and respect those of you with frustrations. In fact, I greatly sympathize with anger towards companies that seem to treat one poorly. I have, on many occasions, been the victim of such unfortunate events. When I...

Hello Folks, I try to sample the various lists as much as possible to see what is new in the world of diving. A friend mentioned you guys were beating on us pretty hard leaving me a bit curious. In reading the various lists I often long for more time because addressing each of the questions...
