manifold set up

[brocotorch]

Hello to all. First time post. Long time commercial diver. I have recently been doing less commercial dive work as i now have a new full time carrer as a registered nurse. I love to dive so i have dusted off some of my old (but still usefull) scuba gear and purchased a lot of new gear. I baught a Halcyon 55lb wing and ss back plate, 2 80cf LP steels and a diverite tank bands and a genesis manifold(din) with isolater valve. I have valve mostly inplace with both bands on. my question is "how many threads on the centerpiece of the manifold are exceptable to be showing?" as my rig sits loosly together right now it appears that the bands will completely tighten with approx. 1/2" of threads still showing behind centerpiece locking nuts" any and all advice will be apprieciated. thanks in advance.

Diving twin steels? if you are dive in dry suit only. If you ever have toswim them up along with all your other gear, you could have a problem. If you took a rip in your bc you could use your dry suit to help in lift. You are most likely diving dry anyway. Rule of thumb:" never dive steels in a wet suit"! as to your manifold, back off a couple of threads. This allows some give,if you ever slam your Isolater into a wreck,and will help against shearing off the valve. Can you figure the scenario you would go through if you sheared your Isolator?What is your personell depth limit? If you go to 200to 250, and you are a healthy, fit diver with good air consumption , a set of well packed 100's plus your deco gas will do you fine on profiles to those depths.If you want to be extra secure in your gas, you can carry an 80cft tank of bottom gas, saving your back gas. When it is empt. just float it up the down line and you will be rid of it and you still have all your back gas and your deco gas and not stuck with a third third tank. You cant shoot up a steel, they sink, but an AL80 will float up and away. Thank You

Reply to my post.... Never dive steel doubles: 100's plus. Along with allyour other equipment and esp. using steel deco bottles also.You will have a wt. problem if you had BC failure.The consider , wet suit compresses and loses its bouyancy potential at that depth. Then,MURPHY ADDS A LITTLE GAS LOSS SITUATION.These are some of the what if's. Now Take a diver that is not that fit, and a lot of them are not that fit that I have seen tries to cope with a little tasking, and has to swim up his rig and handle gas loss, and maintain some proper buoyancy;Humph!! More of a problem then he needed to cope with.Yes, divers do it, and live some do it and die! At least in a dry suit with steels, he has Aux. buoyancey, no wet suit compression problems, BC FAILURE, wet suit backup. This happens in warm water more frequently than you think, where some divers think they don"t need a wet suit.If a diver is going to saddle up with all that wt. and dive that deep, he should be in a dry suit...as they say... "**** happens"!.....Capt Tom
