Halcyon 1 m/3.3 ft Closed Circuit DAM

DAMs and Lift Bags

3.3’ Closed-Circuit DAM (1 m/3.3 ft Tall and 2.7 kg/6 lb Lift)

Halcyon’s 1 m/3.3 ft Closed Circuit Diver Alert Marker is a compact and essential safety tool that ensures you're seen at the surface, even from a distance.

With a closed-circuit design that prevents gas escape, this marker helps divers maintain a clear and lasting presence above water when signaling or separated from their team.

Compact and Reliable Surface Marker

Ideal for both recreational and technical diving, this DAM includes an over-pressure valve for safe inflation, welded seams for durability, and options for oral or low-pressure hose inflation. It’s small enough to pack easily, yet big enough to make a difference when it matters most.
