Transpac vs. Transpac II

[Thomas VJ]

I'm currently looking at either the Rec Wing since it supports doubles or the Trek Wing which only supports a single tank but is smaller than the Rec Wing. I'll be travelling with it and wouldn't mind the smaller size. It's unlikely I'll be double tank dives in the immediate future and, even if I need to buy another wing later, having a small one to travel with wouldn't be a bad thing. I considered the Venture or Travel wing but with only 30lbs. of lift I'm concerned that it might not be enough.

Jason, the Trek Wing will accomodate double cylinders as well but not the big 104-cubic-foot cylinders as the Rec Wing will accomodate. Since you are not planning to use doubles in the near future consider getting the Trek Wing. A bladder to big will give you extra drag and allow large pockets of air to slosh from side to side.

About the Venture Wing, unless you are diving in a dry suit (where the bladder should have enough lift to hold you, your gear and a drysuit full of water on the surface) the Venture Wing is an excellent choise for normal recreational diving. 30lbs of lift is enough for even very big cylinders (remember, the cylinder only has a few pounds of negative buoyancy in the water)

Hi,

On the subject of the transpac vs. transplate I really don't understand how people can say that the transpac does not do doubles well. That is what its designed for...to take doubles. Also if you buy the stablization plates these certainly help to hold the tanks tight against your back. Added to the fact that when diving doubles you've got a structure that is ridgid in itself.

You're quite right, the Trek wing does indeed support doubles. Thanks for catching that - it makes the Trek an even better purchase in my mind. I had originally been thinking of the Venture but after talking to the LDS I left unsure that 30lbs of lift would be sufficient. Now that I think about it, if I'm slightly negative at the surface then the only lift I need to generate is enough to bring me (and my buddy) back to positive buoyancy (plus enough to counter the loss in buoyancy from compressed neoprene at depth). Am I thinking of that correctly? Is there a rule of thumb for determining how much lift you need?
