You might need a snorkel sometime, when you are in the open water. So just make sure you have one somewhere, in a cargo pocket or someplace on your person. GUE-DIR does not emphasize that, since GUE consists of cave protocols, and in caves a snorkel would never be needed since you are never out at sea.
Nonsense ... if you know how to manage your gas properly there is never a reason to need a snorkel while scuba diving. I've managed to log more than 2,000 dives in just about every conceivable condition without ever wishing I had one.
And I sure would not depend on GUE's "deco on the fly." Most of the people whom I know ended up in the hyperbaric recompression chambre were using this when they got hit. They always blame themselves by saying "something must be wrong with me because deco on the fly should have worked."
But it does not work, at least not very well.
More utter nonsense ... and it's quite obvious that you don't even know what the term "deco on the fly" means. In fact, from what you just posted it doesn't sound to me like you understand basic deco theory all that well either.
"Deco on the fly" is not a deco theory ... it's a profile modeling tool. It relies on the same concepts (Haldanian, Buhlmann, VPM, etc) as any other profile modeling tool. Quite frankly if people are getting bent it's because the diver doesn't understand it well enough to use it properly, or is modeling their profiles based on more risk than their body can handle. Those are decisions that every diver has to make, regardless of the modeling tools they are using.
Decompression theory in general is not well understood, and any modeling tool you use ... whether it's V-Planner, Deco Planner, or simply riding your Cochran to the next stop ... is only an idealized mathematical simulation. It's up to you to get enough training to understand what's going on inside your body when you dive, and make decisions based on your personal physiology, the type and conditions of the dive, and how much risk you believe is acceptable.
And since a 3 person "team" can quickly end up as a cluster, you might want to practice solo tech diving, with all its independent redundancy (2 computers), in case you end up alone and separated from your GUE buddies.
That statement right there demonstrates why you should just quit talking about GUE and DIR ... it's pretty clear that you don't know what you're talking about.
GUE isn't the only tech agency that will teach you the protocols to dive successfully as a 3-person team. I do it all the time with my NAUI Tech buddies. Assuming that you're diving with people who's training and skills you can rely on ... and you just shouldn't be doing tech dives with anyone otherwise ... you should never end up "alone and separated". In the rare event that you do, being prepared for it is a given ... it's part of the protocol.
I love you dearly TSM. And so I sure would not want to see you injured by GUE's failures for open water tech diving.
She's far more likey to injure herself laughing over your foolish statements.
Dude, you worry me ... not so much because of your obvious lack of knowledge, but because someone who doesn't know any better might actually take you seriously someday ...
