Salvage divers, underwater archaeologists or anyone who needs to recover a heavy underwater object will appreciate the trapezoidal design of our lift bag. It holds more air at the top, creating a shorter, lower profile bag that is ideal for inflation inside tight spaces. An internal dump valve with pull cord makes it simple to control ascent rate. The open bottom will vent gas in case of a rapid ascent. A built in storage pocket makes stowing and carrying the bag a cinch.
