Best BP/W for doubles? LP108

[cool_hardware52]

Nah im in South Florida... ya i get what you are saying, and i dont even know if ill like all this tec diving and cave diving... But unfortunately i think ill need to spend some money to figure out... at this point im not sure on what i need and i think im trying to get a "get one fit all" type of answer.. or at least something that will get me trough to training... Ill be using double LP95 or LP 108 and i think for the classes i do need a deco bottle.. Since its winter ill probably be using a 7mm... Dive addicts have a great sale on Hollis wings $129 for a 60# wing... would something like that work for my needs at least for now until i figure out exactly what i need... And well after all its only $129...

Im pretty sure the BP will be standard for all my needs, also the harness probably would be standard so the only variable is the Wing..

Humm, big steel doubles with a wetsuit. You might want to talk to a couple instructors before you move forward.

Wing capacity is largely a function of the buoyancy of the divers exposure suit. 108's are not particularly heavy tanks ~-1 lbs each empty.

That is perhaps a function of which LP108 you have. My Worthington LP108's are -2.6 empty and -10.7 filled to 2640.

So, two of these bad boys merely filled to service pressure is -21.4 plus the manifold and weight of the gas in them beyond service pressure.

Still not very heavy. Heavy is a pair of PST 104's, each maybe -5 ~6 lbs empty.

Most steel tanks are somewhere around -1 to -2 lbs empty.


Once again, it is the weight of the gas, and the buoyancy of the diver's exposure suit that determines the required wing capacity.

The buoyancy characteristics of the cylinders used does impact total weighting and may impact the choice of other components such as Stainless Steel vs Lightweight (aluminum or kydex) back plate.

Sure, but this wouldn't affect the size of the doubles wing that much; it would affect the wisdom of diving them wet without redundant buoyancy.

Thanks for all the help, the only reason i wanted to go to doubles is because i wanted to take the advance recreational trimax and double its required by my shop

Those are pretty big tanks. I'll bet that a pair of LP85s would give you plenty of gas for your ART dives and be much easier on your back.

Why most people recommend lp85 instead of lp95 any issues with lp95?

The LP95s are pretty short, which can make them harder to trim. Doubles tend to be head-heavy to start with.

I use Dive Rite 59 lbs Classic Wing and a Hammerhead backplate with my Faber lp108 doubles. I don't have any complaints, but the wing is now discontinued and Hammerhead Backplates went out of business. I also use a 5 lb V weight and a 6lb P weight. The wing does float the weighted rig by itself.
