Stuart Morrison sendte noget til mig den 19:41 19-04-99 som indeholdt=20 pr=E6cis . . . In UK waters a lot of divers tend towards thick neoprene drysuits. All this can restrict movement which might make reaching valves harder. - One should NEVER use thick neoprene suits when diving deep as the lousy=20 bouancy characteristics leads to all sorts of problems with weighing. Check= =20 the archives for specific reasons or write again. Get a shell suit og a=20 compressed/crushed neoprene suit (I dive DUI CF200) and some decent=20 underwear. Add to this the loss of dexterity and hand strength that cold brings, and the fact that cold water divers are at a higher risk of freeflowing regs and it could all end up going horribly wrong when trying to shut valves down. - What I do if I have loads of underwear on and dive with small tanks (2 x= =20 10L) is that I loosen the waist band before reaching to close my valves.=20 Then there is no problem. You can still close your valves in 10 seconds. My technique is to leave the isolator on the manifold closed, so that I'm effectively diving with independant tanks. If I have a freeflow, etc., I'm not under the same pressure to do something about it. If I reach my valves then great, but if I don't then it's not a problem, I still have half of my gas safe. - Do as above and you won't have to resort to this type of strokery.=20 Independents, which is what you are arguing for, lead to numerous problems.= =20 Check the archives for a full summary. A couple of other things. I like to use climbing karabiners on my stage tanks because they are big and easy to use with cold hands. - Use piston bolt snaps. These cannot get you jammed and they come in large= =20 sizes as well as smaller. This is the only acceptable type. I use them in=20 different sizes on my gear. On my (alu) deco bottles I use a type that's 10= =20 cm long as the deco bottles are large and more cumbersome to move around.=20 On the rest of my gear I use the standard size. Some people say that they are an entanglment risk because they open and close so easily, but like my cave instructor once told me, you shouldn't be close enough to get tangled in the first place. - Eeer, shit happens?
