As a casual rec diver, I don't have much need for lift bags, but when I stumbled on Subsalve's booth at the 2006 DEMA show, I was amazed with how large some of the bags were. Some of the bags were as big as a person. These bags are for commercial use and are designed to be used by a single diver. Each of the bags comes with a Plunger Dump Valve, which provides air control with a push-button knob at the top of the bag and a lanyard at the bottom of the bag.
Subsalve also makes a Vehicle Recovery System (VRS). Used in pairs, the VRS makes floating sunken cars easier.
Much to my surprise, the booth attendant explained to me that the bags on display were actually quite small. Subsalve also produces professional-grade lift bags -- like the PF 70,000 -- which is more than 21 feet tall and is capable of lifting 77,000 pounds.
1. not much use for a lift bag?? ohhh, willy, if ye only knew. lift bags are great for use during a dive where you find that you need ascend away from the boat's anchor line. they're excellent for helping carry large quanities of scallops or that wonderful hunk of brass junk one might happen across. and they can be tucked away by simple elastic bands and are used with the addtion of a wreck reel... so for safety and convienence, they're hard to beat! give it a go.
