Spotting for a valve drill

[TSandM]

Yeah, well, when YOU do a valve drill, you make it look trivial. You may excuse yourself from this discussion of what mere mortal, mistake-making people do when they have to do valve shutdowns

I have not had to buddy-breathe on any GUE class, and I do not think it is on the "required" skill lists for tech1/2 or cave 1/2

Nope, not part of the GUE curriculum. The long hose kinda makes the point mute.

While the long hose is reasonably quiet, I'd hardly call it mute The point is moot, though. :1poke: :1poke:

I'll take your long hose, you can breath off the power inflator :mooner:

I haven't taken Fundies or any GUE course yet, but I find it interesting that it's not in the curriculum since it's mentioned in JJ's book. I don't have the book in front of me right now so I'm working off of memory but the book gives examples of mastery levels for various skills and for mask remove/replace (for instance) the book mentions that an advanced diver should be able to swim maskless for 100' while buddy breathing and then replace the mask within 10 sec. There are a few other examples of skills that mention swimming while buddy breathing if I recall correctly. Is this just outdated info that's been removed from the curriculum, or is it just an example given in the book that's not in the class?

I'm not sure of the phrasing in JJs book (which is not a training standards document, btw), but if it is referring to "buddy breathing" they are actually referring to one diver on the long hose, the other on the backup reg, not a maskless exit with only one functioning regulator on the team. That's an insane number of identical failures to have happen and time would be better spent avoiding those failures rather than learning how to react to them.

Bingo! The only time when buddy breathing might be warrented if for a failed/lost deoc bottle. Some people (particularly in the UK) are being taught to 1.5x the deco time at each stop and share the bottle.

4 mins turns into 6 mins with 3 mins on the bottle for each diver. Not "buddy breathing" per se, since you breath backgas when not using the bottle.

Here in the States (at the Tech1 level) most are being taught to just double the deco time and reshape the curve.

Yeah, but like you said, that's not buddy breathing, that's donating gas at a predetermined time. Mostly not worth it unless you have a substantial decompression obligation, not enough gas, or other emergency.

Yeah I think the sharing one regulator biz went out with the J-valve. Its a good skill to get people more comfortable in the water. But it has virtually zero use in a cave or deco situation.

Unfortunately, some of the ease with which we use manifiolds and long hoses can bite us when we also have a loss of bouyancy going on - as in what appears to have happened while ice diving in Ontario this past winter.
