Matjack presents underwater lift bag. This diving equipment provides value whenever it is used. The bags feature one or several handles and tie-off points. This simplifies grasping and securing of these bags - both in and out of the water. Their design allows folding and rolling of bags into small and negatively buoyant rolls. Due to this, the diver can easily handle and deploy these bags underwater.
The underwater lift bags are equipped with over-pressure valves. The valves allow optimum venting of air from a completely charged bag - on a free ascent for any distance down. The bags are very adaptable and are suited for light-to-medium-duty. They are ideal for sport divers. They can be used for nearly all kinds of underwater lifting and light salvage. Except the 25- and 50-pound bags, all bags feature diver-actuated dump valves, and all are open at the bottom for venting expanding air as upward movement.
