The great independents versus isolation manifold debate

I put two pieces of surgical tubing on the leftside of the back plate. One piece near the top and one near the bottom. I stuff the hose in there with two wraps leaving enough out to where it comes under my left arm pit. I put a small piece of velcro on the reg to keep it in place. When I am not diving I do not leave the hose wrapped up that way it will keep it's natural shape. I can deploy that hose just about as quick as I can when I wrap the long hose around my neck.

Bruce,

Do you ever practice OOA drills?

This is a debate that has gone on since the beginning. I use a manifold with an isolator. IMO, this certainly makes for the cleanest configuration. The manifold does have one potential disadvantage in that if the manifold itself fails there is no way to deal with it. I only know of one instance of this but it can happen. With the number of divers using scooters seemingly earlier in their career I wonder if we aren't about to see some more manifolds busted.

The guys who dive small caves with low vis where access to a teammate is limited or nonexistant, insist that valves belong in the armpits on independant tanks. I this case they have a point and this style of diving is nothing new and it works where other systems fail.

I came across this discussion, and I am very surprised it lasted this long. OK people, think. You should NEVER use doubles without an isolator manifold. The manifold should be a 300 bar isolator manifolf exactly like is available by Halcyon or an exact spec copy. This is not only a safety issue, but a common sense issue. There is absolutely no way you should do it any other way.

There is a reason why the worlds best tec divers have their configurations and setups this way. It is safe and it works. Don't try to re-invent the wheel, and don't add your name to the DAN fatality list by being stupid

Also these cords that people some times use under their arm pit so they can turn the valve off is an accident waiting to happen. Stay away from them, there is a long list of problems associated with these. If your isolation valve is cantered at a 45 degree angle you simply bend your arm and turn the valve behind your neck.

Practice, practice, practice.

I was refering to sidemounted tanks not some kind or extenders for divers who can't reach their valves.

At top of page http://www.omsdive.com/valve-access.html. For what it's worth, I am pretty sure these also passed the boat prop fish scale drag test..

Love that condescending tone!
