Perrone NOTHING was lost. ScubaDrew could be talking about a host of issues that can happen in a nano second leaving him without air...a blown o-ring is one...when my hose sheered off diving a wreck I did not entirely clear as a second one...and others.
When I say lost, I am not referring to ScubaDrew. I am referring to the attitudes of a great many divers I see and talk to. I've had a blown o-ring scenario. 500ft back in Jackson Blue cave at 95ft. Stuff happens. The question is how do we prepare for it with gear, and skills. My perspective could be totally wrong here, but it seems like people are taking the approach of a "pony bottle" first, and buddy second. When I took OW class, we were taught that our best option was our buddy. My technical training beyond that has emphasized the same. A solid buddy can anticipate problems and be ready with solutions BEFORE things happen. A solid buddy will see that you are about to not clear that wreck's door and will probably shear a knob or hose. A solid buddy will notice that your fins are about to get wrapped up in the line in a cave, and work to prevent a possible catastrophe (I had to do this in Little River Cave Aug. '06). Having redundant air isn't a bad idea per se, I guess I just have problems with it being promoted as a substitute for a good buddy.
If you insult people they will tune out what you have to say...even if it is valuable. And your suggestions are valuable but they get lost in your delivery.
Hmmm, I didn't see that my post was insulting. I wonder if ScubaDrew saw it that way. Someone else PMed me to say they didn't see it as insulting either. Did it really seem insulting to you, WW?
Furthermore, ScubaDrew is a newer diver. He hasn't had the experience that you've had. He is trying to learn and he is doing a great job looking at these issues NOW early in his diving experience. He may not have the ability to drive to a great dive destination on a regular basis like you and others do in cave country and therefore build up a great group of REGULAR dive buddies.
I agree he seems to be doing a great job. Asking questions and getting into these philosophical discussions is a great way to learn. I will vigorously support my position, and I expect others to do the same. Back it up with examples and experience, and we can all benefit. There seems to be a misnomer here. You think I have an opportunity to build up a great group of regular dive buddies? It's taken me 2.5 years to find 3 local divers I'd do a cave dive with and feel comfortable. You have to find someone who shares your ideas about diving, then practice with that person in a pool or pool like setting. Work out the kinks in communication. Understand what each other wants to accomplish in the water. One of the divers in my normal team of three broke our safety rules while diving with another team. We dropped him. Now we are looking for a different third diver, and I think we've found one after 4 months of looking. This stuff isn't easy no matter where you live.
To always assume people have access to great dive buddies or dive teams, grossly ignores the reason most people are on this site....they want and need good buddies. And yes the *great* buddy is and does all the things you list...problem is that we aren't all *great* dive buddies and we all don't have access to *great* dive buddies.
I don't assume anything. For the most part I don't have great dive buddies. Which is why I still do so much open water and shallow diving. My best dive buddy is not cave trained, only cavern. I'd rather limit what I do in the water, and dive with that person, than push a cave dive with someone I don't trust. If I don't have a great dive buddy (weak insta-buddy, or newer diver), then I dive to the level I feel comfortable with them. Great dive buddies usually have to be built. Over time. And in varying conditions and scenarios. I think this site does a great job at trying to provide that for people by allowing folks to talk and compare experiences, and even meet socially with other divers prior to jumping in the water. Since I have not been on an SD trip, I don't know how well it works in practice to prevent the usual insta-buddy issues. From what I hear, it seems to work great.
As for testing OOG (out of gas) or OOA (out of air) scenarios...your suggestion to talk about it with your dive buddy and PRACTICE it are great. I highly recommend it and usually do it myself but like many others...need to be more diligent in it. I should as others have done...make it part of my dive ritual.
I think it's a great thing to do early in the dive. And when it's part of SOP, you aren't likely to forget. And it might just alleviate some fear for that new instabuddy, by knowing they have a solid and competent dive buddy.
Regarding pony bottles...they are great...
I think they "can" be great. Or at least quite helpful. But like anything else, practice with them is required if someone expects them to "save their lives".
As for always relying on great *buddies*...even great ones can't always be there to help you. Several very well respected cavers on this site have given numerous references to instances where a buddy was in front of someone in a narrow passage or a few feet away but silted out or otherwise unable to help. You must rely on yourself first and then your buddy as part of your tool arsenal. For example, if you panic you not only will not be useful to your buddy but you won't be able to help yourself and you limit what your buddy can do for you. If you are narc'd the same applies. And YES these both happen to good, seasoned and experienced divers. So of course they will happen to the rest of us as well.
Yes, even great buddies can't always be there to help you. The question to this is why. If a great buddy can't be there to help you, it should stem from the fact that they are either incapacitated, or somehow restricted. I've read the reports of some of the cavers on this site, and I think they will admit as easily as anyone else, that poor buddy protocol happens in caves as well as open water. The consequences are usually more harsh though. Being able to rely on yourself first is absolutely critical, especially in an overhead. But trained overhead divers take great pains to mitigate the risk. It should be noted that in cave training, passing through restrictions where a buddy might be out of reach for some time, is reserved for the final certification off Full Cave. The previous two courses, do not allow this. In other words, even in this elevated training, circumstances where a buddy is out of reach should only apply to those who have demostrated a mastery off all other skills including self-rescue and rescue of a buddy.
While I agree with your comments on being paniced, I do not necessarily agree with your comments on being narced. I am not saying it doesn't happen. We all know it does. But it is a solvable problem with training and proper diving gas selection. It is an avoidable problem, much like not diving with faulty gear. Many of us choose to take this unnecessary risk, myself included, though I do try to choose my dive buddies VERY carefully, if I am diving to depths where being narced is a good possibility. I broke this rule once, and will never do it again.
