DPV gas planning

[jj1987]

Seriously? That's a thing you teach?

No wonder this is so complicated. Learn to tow efficiently. Link up, share from your buddy's backgas, and gtfo.

I'd love to hear a reasonable situation where sharing gas while scootering is a real thing.

Sorry, my joke sounded like it was directed at Rob, whom I never even met.
It was not intended that way.

One can't say if that is a "thing" that Rob teaches,but it is taught,and with all skills has a correct technique,and can be don't efficiently. Where my preference would be to pass off a stage,but it if the SHTF,this can be done quite well if you have a buddy versed in it. To practioners of DIR this may seem contrary to what you are taught, but at the same time many non-DIR people have always thought GI3 was nuts in teaching people to breathe off their dump valve in an emergency. I prefer to be open minded and learn from everyone,use my ability to use critical decision making to determine what is something to keep in my bad of tricks,and what to dump.

i dont think it's just 'DIR' folks who can see all the problems with trying to negotiate cave passage while tethered to an out of gas diver on a long hose.
just because a thing can be done does not mean it should be done

You're dramatically increasing the odds of the reg getting ripped out of your buddy's mouth. That would be bad. It also breaks down every time you need to travel single file.

No thx.

Not to hijack the thread, but since you asked, IMHO manifolded doubles can create such a situation.

I agree it isn't without flaws and requires a lot of practice to be proficient,but as I said I would prefer to know a skill to increase my chance of survival than not. We have redundant regulators out the yin yang,so we shouldn't know how to buddy breathe to accomplish an exit-correct? About 25 years ago a team survived because they used bubby breathing when they had a serious situation. From that I made a couple buddy breathing exits for practice. Like I said something that less than ideal,but another skill set that increases my percent of survivability.

If you can't dive your equipment (ie reach and manipulate your valves), then sure.

Actually it's not as bad as it sounds. We did this drill in DPV class exactly where we did the standard lights out OOA drill in cave classes. That includes negotiating a restriction.
Both scootering while tethered, plus going through the restriction while tethered, is actually not that difficult, assuming the rest of the skills are solid.

I think sharing gas while scootering together decreases your odds of a good outcome. To slow, too many variables, too easy to rip out the donated reg.

Getting into a proper towing position means the lead diver can go the entire exit without getting off the trigger, even through narrower bits.
