Open Bottom Lift Bags are very versatile light-to-medium-duty lift bags. They are excellent for sport divers, and are suitable for most types of underwater lifting and light salvage. All but the 50 pound bag have diver-actuated dump valves, and all are open at the bottom to vent expanding air as they ascend. They are economical, lightweight, and fold into a neat, compact roll for easy handling underwater.

Enclosed Pillow Bags are totally enclosed, with over-pressure valves to vent expanding air as they ascend. The advantage of Pillow Bags over the Open Bottom Bags is that they can attain their maximum lift in much less water. For this reason, they are excellent for raising sunken boats, and for towing jobs. Like the Boulder Bags and the Ocean Salvage Tubes, all Pillow Bags come with brass quick-disconnect fittings attached to a short filler hose (connects to 1/4" pipe thread). Please see the table below for sizes and pricing.

Salvage Tubes are highly versatile in the number of ways in which they can be deployed. They are excellent for pipe-laying and other underwater construction projects, but where Salvage Tubes really come into their own is when they are used in raising sunken boats. They can be used vertically to bring the boat out of deep water. When the boat is suspended near the surface they can be slung under the boat with one end on each side to raise the boat high enough out of the water to pump out. In shallow water, two bags can be slung together, one on each side of the boat, like pontoons. They can also be used as rollers for moving beached boats back into the water.

Boulder Bags derive their name from gold dredgers and nugget hunters who use them for lifting boulders in the shallow rivers of California's mother-lode country. They are designed to get a maximum amount of lift from a single lift-point in a minimum depth of water. For example, the 2000 pound Boulder Bag gets its total lift in less than 3 feet of water, whereas the 2000 pound Open Bottom Bag requires almost 8 feet of water. These bags are very durable and have been used as air jacks capable of exerting several thousand pounds of force over a large area.

Propeller Bags are specifically designed for installing and removing boat propellers, but they are well-suited for several shallow water lifting jobs. To stabilize the lift of a heavy prop, it is often necessary to lower its center of gravity by attaching a weight to its lowest blade.
