Carter: Boulder Lift Bags - (Liftbags)
- All Carter Bags have one or more handles and tie-off points
to make them easy to grasp and secure both in and out of water.
- All Carter Bags are designed to be folded and rolled into
compact, negatively-buoyant rolls that are easy to handle and
deploy underwater.
- The over-pressure valves on all Carter Bags are designed
to adequately vent the air from a fully-charged bag on a free
ascent from any depth.
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.
