The 31 kg Polaris Lift Bag is a professional piece of equipment designed for recovery operations, removing loads from the bottom, or as a redundant signaling and emergency buoyancy device. With a lifting capacity of 31 kg, this lift bag fully complies with the rigorous DIR (Doing It Right) requirements of technical diving, ensuring maximum linearity, hydrodynamics, and safety of use.
Technical and Mechanical Characteristics
-
Closed-Circuit System: The bag is completely sealed; inflation is controlled via a dedicated inflator hose. This design prevents accidental air leakage from the bottom if the lift bag tilts during ascent, maintaining constant hydrostatic thrust.
-
Overpressure Valve (OPV): Strategically positioned to automatically vent expanding gases during ascent to the surface, protecting the fabric from overexpansion and structural damage.
-
Space Optimization: All anchor points and accessories are installed and positioned to allow for neat folding and optimal storage, minimizing bulk when the lift bag is stowed.
Anchor Points and Integrated Accessories
Upper D-Ring: A robust D-ring is present on the upper end, ideal for attaching luminous signaling devices (strobes/v-lights) or for securing wetnotes (underwater notebooks) for sending messages to the surface.
Stainless Steel Carabiner: Supplied as standard with a high-strength marine-grade stainless steel carabiner, configured to allow:
- Quick and secure attachment to the spool or primary reel line during deployment.
- Tidy and stable attachment to the harness crotch strap D-ring during transport underwater.
