Supra Closed and Semi-Closed Lift Devices

SCC 60 Lift BagDivers are discovering that lift bags are useful for much more than just salvage and underwater lifting. Halcyon's lift bags can be inflated through a low pressure inflator hose and feature a one-way valve to ensure that the bag will maintain lift all the way to the surface.

Whether used as a marker device while at depth, supplemental surface flotation, or as a signaling device, lift bags provide an added margin of safety and comfort. Halcyon lift bags fold so small they can store in the Halcyon thigh pocket or Backplate Pak

Lift Bag DeploymentHalcyon now includes a Semi-Closed Circuit 60lb. Lift Bag in their lift device product line. Halcyon's SCC 60 was designed to allow for easy lift inflation for a wet suit diver who wouldn't otherwise have a spare low-pressure inflation hose handy. Designed to be filled by a diver's second stage regulator, the SCC 60 combines the ease of inflation of a traditional bell-bottomed lift bag with an over-pressure release valve to dial in a precise amount of lift and to prevent damage caused by over-inflation at depth.

SCC 60

  • Semi-closed circuit design, perfect for wet suit divers
  • Over-presure valve allows for lift modulation during salvage lift operations
  • Baffled inflation chamber prevents accidental dumping in rough conditions

CC 80 & 185
Of course, Halcyon's Closed Circuit 80 and 185lb. lift bags are still the industry standard for technical applications where precise control over lift and surface control are essential.

  • Closed circuit design means the object of a difficult search will reach the surface without the risk of inadvertently dumping, losing buoyancy
  • Safety orange color is easy to spot by passing surface or air traffic
  • Available in 80 lbs. and 185 lbs. lift capacities
  • All Halcyon lift bags attach to a low pressure inflator hose using a No-Lock connector and can be orally inflated when necessary

Specifications: OPV Valve, sea rescue orange, RF welded, single bag construction, No-Lock connector, stainless steel attachment hardware and elastic cord retainer

DIR Tip 14
To prevent an out-of-control lift, the diver must first try to match the lift capacity of the bag to the weight of the object for example, use a 100 pound bag on a 100 pound anchor, or as close as possible. In this way, the excess air is vented out of the bag, never generating more than 100 pounds of lift. Secondly, with larger bags, the diver should be prepared to vent excess air from the bag as it rises to the surface. For safety, the diver must be careful not to get his or her gear entangled in the rigging, must never get above or below the load and should not exceed the recommended safe ascent rate for a scuba diver.
