OMS Dual Bladder wings. 60lb, 94lb Difference?

[dieseltrkin]

OMS Dual Bladder wings. What is the difference between a 60lb or a 94lb dual bladder. I know what the weight means. However, in terms or dual tanks and deco bottles, can a 60lb still do what a 94lb can? I am asking this because I am crossing over to the "TECH" side (with a deep laugh) and I am looking to purchase an OMS dual bladder. I am 5'11" and about 190lbs so is there a difference for bladder poundage again, 60 or 90. I plan on advancing through to Advanced trimix so any and all help is greatly appreciated.

I can't imagine what sort of rig would ever require 94lb of lift.

I will give you the "Certified Cyber-Diver" answer: Ask your instructor. The answer will almost certainly not be 90+ pounds of lift, but that's irrelevant. The important thing is that your instructor may have strong opinions about your rig that will dovetail with the system he teaches. Some systems bar bungeed wings. Some systems bar double bladders. Some systems call for a short inflator hose with no integrated dump valve. And so on.

Your instructor will also have a good idea of how much gear you will be diving as you progress through his training. A wing suitable for double AL80s may be different than a wing suitable for double HP-130s plus a stage and a deco bottle, which may be different again from a wing suitable for sidemounted tanks.

The best thing to do is pick your instructor first and get their views on the gear you should purchase.

Why dual bladder?

Why dual bladder?

Redundant buoyancy

If you find an instructor that says you need a 94lb wing, its time to look for a new instructor.

I don't imagine myself doing stupid things like trying to break OC depth records. If I ever wanted to do a 300 mt dive I'd start with the right gear for the job, & OC wouldn't be in the race.

OMS Dual Bladder wings. What is the difference between a 60lb or a 94lb dual bladder.

One is probably too big, the other is probably WAY too big.

You might also want to re-think the dual bladder idea. I realize it's part of some tech organizations' training, but others use a lift bag when you're diving wet. If you have a high quality wing, catastrophic bladder failure is pretty unlikely. Power inflator failure is much more likely, and you can just disconnect and orally inflate in practically all cases. If you're concerned about bladder tears or punctures from a hazard, think about the fact that your secondary bladder is just as vulnerable while a lift bag is stowed and protected.

I'm not suggesting you should; you posed a question, I provided an answer. JB used an OMS 94lb dual bladder wing on that dive
