I have a small (womens) Aqualung Sea Vest. One of the weight pockets is gone, how do I know if I should get a 10 pound or 16 pound pocket?
The Aqualung web site has a page with a complete list of what Surelock II pouches fit what BCDs. It includes the following:
"SureLock?II Weight Pouch (10 LB) compatible with:
Pearl, Pearl i3, Dimension i3, Lotus i3, Balance, Libra - All sizes
Axiom, Axiom i3,Pro QD & Pro LT ? Sizes: XS, SM, MD, ML"
You don't say what model your BCD is, and I do not know if it is compatible with Surelock, Surelock II, or both. I suggest contacting Aqualung.
Okay, let's start at the beginning. If you have a seaquest surelock system of integrated weights pouches and you have a small size, you will use the 10# pouch. It has to look exactly like the one the L. P. is showing on this window that will work for your bcd. Unless you have a black diamond bcd. The black diamond takes the 16#pouch.
There is a older version that uses velcro to hold it in. That is not a surelock system. Look at the remaining pouch and order that same one.
Good luck and good question.
The 16 lb pocket is for the XL size. If you have a small size, you want the 10 lb pocket. That would give you 20lbs of weight, plus up to an additional 5 lbs in each of the upper back packets. If you are small, it is unlikely you need more than 30 lbs when you dive.
Check your remaining pocket. The small ones only take one "row" of weights, the larger one has two sub-pockets and will hold two "rows" of weights.
