Halcyon Super Big Closed-Circuit DAM – 1.8 m / 6 ft • 23.6 kg / 52 lb Lift

The Halcyon Super Big Closed-Circuit DAM is designed for divers who need exceptional visibility and dependable buoyancy support. Standing 1.8 m / 6 ft tall and 25cm wide, this closed-circuit surface marker sits high above the water, making it easy to spot in rough seas or from a distance—ideal for signalling, support, and managing surface operations.

With 23.6 kg / 52 lb of lift, it also serves as a reliable tool for light-duty recovery, gear support, and emergency buoyancy. Built with rugged materials and radio-frequency welded seams, this DAM is made to withstand demanding environments and repeated use.

A one-way oral inflator and over-pressure relief valve ensure safe, controlled inflation at depth or on the surface, while US Coast Guard–approved SOLAS reflective tape enhances visibility in low-light conditions.

FEATURES:

• 200 denier nylon
• Easily inflated at depth
• Diver’s Alert Markers use an integrated over pressure-relief valve, allowing them to be deployed from depth
• When deflated, all markers fit in a Halcyon thigh pocket or backplate MC Storage Pak
• Big and Super Big Alert Markers are marked with Coast Guard approved SOLAS reflective tape
• Halcyon Diver Alert Markers (except semi-closed model) feature our No-Lock® connector for oral inflate or LP hose connection
• Halcyon offers several Diver Alert Markers in a variety of colours. These combinations support divers that wish to carry one colour to mark position and one to mark emergencies.
