Nemrod:
Soggy, MengTze, everybody naturally applies their situation to geneal discussions, your a cave diver so this or your a deep wreck diver so your buddy this and whatever buddy or that, all I can says is that counting on a buddy is very likely someday to leave you wishing for more than a pair of scissors. Buddies don't come in a box with a 100% guarantee or money back or your life back.
If you don't see the need to practice basic watermanship skills then don't, don't practice all that DIR stuff like so called helicopter turns and air sharing S drills or any of that, don't practice anything, your never going to need that---or will you? N
Maybe so Nemrod,
But the thing is (and I was being a bit facetious in some previous posts) that the skills we are talking about are a patch on what is the underlying deficit: awareness and forward looking.
I see things written like, getting stuck under a rock/in a wreck, narrow passage, line etc. If you are looking ahead and think before you do, you will not (should not) get stuck under a rock. If one needs to go into those narrow places, do side mount.
Don't let a DM put your rig together either. Do it yourself and double check what you did. Avoid being in the situation.
Line entanglement, gets worse as we all know with movement, I dont believe one initially gets so stuck/entangled that you can not move. your movement after that first moment starts making it worse. If you get entangled there is an opportunity to get untangled/cut yourself free (buddy or self).
I firmly believe in not getting in that situation in the first place.
Practicing all that DIR stuff and such, well on a VERY regular basis. But that is not the issue, the issue is that people
'seem to get into situations' and then practice don/doff to get out of it. I try to prevent getting in the situation in the first place. Nothing to do with Cave or Wreck diving per se. Something we all as divers should be working on. Be aware of what is coming up and stop to think before acting.
BTW it is easier to don/doff with jacket BC and single tank than with doubles, stages and such... this is another reason why you try to prevent being in the situation in the first place.
