The Halcyon 80Lb Lift Bag delivers 36 kg of lifting capacity for technical diving operations requiring precision and safety. Its closed circuit design minimizes air loss while the integrated one-way valve prevents backflow at the surface. An over-pressure relief valve manages expansion safely during ascent, protecting both diver and equipment. Purpose-built for underwater recovery and decompression support, this lift bag combines reliability with the redundancy serious technical divers demand.
