Many thanks Kent for an excellent and constructive post. I certainly =
will not be letting go but I think the overall non-clutter aspects of =
the principle are, as you say, where I should be focussing.
A big thank you to all who replied. All your suggestions will be taken =
on board. I feel I have learned a great deal.
Safe diving,
Tim

You simply can't get yourself and your rig both neutral when cold =

Here in Alaska our conditions are very similar to the North Sea, if =

What most serious divers do is just accept the fact that your rig and =
you will not be both independently neutral when separated. With a =
drysuit you won't lose your rig because you'll still be attached at the =
drysuit hose even if you take it off. Furthermore, the only real =
instance that you'd be taking it off would be inside a wreck in a =
serious restriction in which case neither you nor your rig are going =
anywhere. In open water there's no need to take the rig off and you =
don't want to. With a proper DIR rig with no serious points for =
entanglement then you shouldn't get entangled in stuff. The only real =
place where you can get tangled is with the manifold which you can reach =
with your hands anyway. With nothing attached to your tank and no tank =
boots or other crap hanging off you then your risk of entanglement is =
very low. That's what you should focus on.
=20
Also, try taking off your rig underwater. It's really not that much =
of a big deal even if it is negative and you are positive. You just =
don't let go, keep an arm through one shoulder strap. If you do let go =
you are still connected with the drysuit,

Subject: ditching the weight belt
I am in the process of converting to the DIR system as it seems an =
emminently logical, efficient and sensible method. My present diving is =
mainly wrecks in the eastern end of the English Channel. My only concern =
with the system is the ditching of the weight belt in favour of V =
weights. Having said that I am aware of the benefits of the streamlining =
and less clutter, which greatly appeals, but please put my mind at rest =
as to what happens if you need to remove your kit at depth, say in the =
event of an entanglement. Yes, I know you should always have your buddy =
for such occasions, but it is very easy to get separated, especially =
when the vis is down to the 1 metre mark. I would emphasise this is a =
hypothetical situation: I have been entangled and I have lost my buddy, =
but never at the same time. The thought of my kit heading south as I =
head north is not one I wish to contemplate. I am sure there must be a =
simple answer.
