Doubles question

[novadiver]

OK - with respect - why can't they reach their valves? Do they suffer from a lack of flexibility (which is a physical fitness issue) and are therefore too lazy to get in shape, or do they suffer from a physical handicap? Secondly, if they do suffer from a physical handicap, is the slobwinder on the isolator? If so, why can't the reach the isolator with their other arm?

Shy of having a disability or amputation, I can't ever see the need for one of those things.

Which is the answer to JasonB's question - there's nothing wrong with your buddy manipulating your valves. But care to speculate? Your buddy is OOA - no problem, after all, you've practiced that. So on your way out you're passing through a restriction, your buddy is on your long hose and "poof" - you roll off your left post. Your buddy is ahead of you... happily getting air.

Well, unfortunately, because you can't reach your own post, you are going to drown. This is, decidedly, not a good thing.

Ask yourself - is it better to work on fundamental basic dive skills, or to simply buy equipment to compensate?

But before you die you get really mad at yourself for putting a short inflater hose on your wings , because a longer inflater hose would have let you hit the inflate and dump buttons at the same time and hit off the hose untill you were out of the restriction and could fix the " roll off " problem. This is another good reason to have your wing supply hose come from the right post.

Thanks Jonnythan,
Apparently I don't know how a manifold works (well, I do now-thanks for the lesson guys). I'll shut-up now.

Again, thanks to all for the help,

Jason

Even with my short inflator hoses, the hose is still long enough to get to my mouth.

But yes... you only die if you have your inflator coming off the rolled off post.

If my tank blows an o-ring on a single tank rig, what is gained by me being able to reach my tank valve.? Agian, OOA/OOG drills should aid in this shouldn't they.

In addition to Soggy's answers...

Not shutting down a freeflowing tank does a number of things. It adds confusion to an already confusing situation. A rapidly dumping tank will quickly change your bouyancy, as a full to empty single 80 will make you about 7 lbs lighter during the time it empties.

Of course, one could argue that your buddy could turn off your valve. However there is the other side of it. If for any reason you should get separated from your buddy's long hose during your egress, you are now out of gas whilst actually -having- gas. In a separation situation, you can turn back on the tank and potentially breathe off the freeflow/leak.
