DGX Gears Large Lift Bag { 120 lb | 55 kg }

The DGX lift bag offers a semi-closed bottom design with a teardrop shape and true† { 120 lb | 55 kg } lift capacity. This is perfect for larger salvage projects and can also be used as a surface marking buoy for decompression or safety stops in the open water. Constructed of durable 400 denier polyurethane coated nylon material in high visibility orange, the bag is RF welded and double stitched. An over pressure valve (OPV) allows excess gas to vent during ascent, and includes a pull dump to deflate the bag before boarding the boat or when being folded for storage. The stainless { 1 in | 25 mm } D-ring on the end of a { 18 in | 48 cm } long webbing Y-lanyard at the bottom of the lift bag is for attaching the line or load. The nylon { 1.5 in | 40 mm } D-ring at the top provides an attachment point for a light, strobe or slate. We suggest adding an optional DGX mesh sleeve for storage and attachment to your harness.

The semi-closed design is open at the bottom and incorporates a funnel-shaped (aka 'duck-bill') internal baffle restriction that allows the bag to be slowly inflated at depth, but prevents it from unintentionally deflating while on the surface. To fill with gas hold the opening over a second stage regulator or BC oral/power inflator, or hold the mouthpiece inside the opening, and operate the device to slowly release gas out the mouthpiece into the bag. The bag is not fully closed by design and if you inflate it when dry (i.e. at home, to 'test' it), you will discover gas slowly leaks out through the bottom baffle. This does not cause a problem in actual in-water use, where the water will cause the baffle to seal.

† The OEM called this a 150 lb lift bag, but it's our logo on it so we actually measured the amount of water this lift bag will hold! We found we could fill it with about { 14.4 gallons | 54.5 liters} of water, which would also be the maximum amount of water it could displace when filled with air. Archimedes' Principle tells us that means it has about { 120 lb | 54.5 kg } of buoyancy in fresh water and { 123 lb | 55.9 kg } of buoyancy in sea water when the bag is fully submerged.
