This scuba diving lift bag combines practical design with durable materials to deliver reliable buoyancy control in a compact form. Its features are focused on safe ascent, efficient air management, and longlasting use in underwater tasks. Key benefits Efficient air management with a trapezoidal shape: More air stays at the , creating a shorter, lowerprofile bag that is easier to deploy and maneuver in tight spaces. Safe, controlled ascents: An internal dump valve with pull cord lets the diver vent air while ascending, enabling a controlled ascent rate and improved safety. Durable and visible: Constructed from fluorescent nylon cloth with TPU material for durability and visibility in lowlight conditions. Practical air expulsion from the bottom: Bottom opening design with dump valve gear allows air to be expelled from the bottom, supporting practical venting and stable buoyancy. Materials and construction Fluorescent nylon cloth with TPU coating for durability and visibility Internal dump valve operated by pull cord for onthefly control during ascent Bottom opening design with integrated valve gear for easy bottom venting Design and performance highlights Trapezoidal shape enhances air positioning for a compact, lowprofile bag Internal dump valve with pull cord supports controlled ascent and safer depth changes Bottomopen design enables efficient air expulsion from the bottom for precise buoyancy adjustments Durable construction suitable for repeated use in demanding underwater tasks Use scenarios Underwater lifting and salvage: Attach a load to the lift bag, inflate to lift from the seabed, and use the pull cord valve to control ascent speed for a safe surface transfer. Divers performing bottom work: Use the bag to provide stable buoyancy and safer handling of tools and equipment during wreck inspections, installation, or recovery operations. Surface recovery and visibility tasks: The fluorescent material aids visibility during surface operations and helps locate gear after deployment in murky conditions. This lift bag stays true to its core function and construction, offering reliable buoyancy control, durable materials, and practical design features that support common diving operations without adding extraneous details.
