Halcyon diver's alert marker 3.3' closed circuit

Description

The Halcyon 3.3 ft Closed-Circuit Diver Alert Marker (DAM) is a compact yet highly effective safety device designed to increase diver visibility during ascents, safety stops, decompression dives, and surface signaling. Standing 1 meter (3.3 feet) tall and providing 2.7 kg (6 lb) of lift, this closed-circuit marker offers dependable flotation while remaining small enough to fit easily inside a Halcyon thigh pocket or MC Storage Pak.

Built for both recreational and technical divers, the closed-circuit design traps inflation gas inside the marker, allowing it to remain fully inflated at the surface for long-lasting visibility. The integrated over-pressure relief valve enables safe deployment from depth by automatically venting expanding gas during ascent, while Halcyon's exclusive No-Lock® connector allows convenient inflation using either oral inflation or a low-pressure inflator hose.

Constructed with rugged welded seams for long-term durability, the 3.3 ft DAM is built to withstand years of demanding dive conditions. Available in Orange, Yellow, and Shocking Pink, divers can carry different colors to distinguish routine position marking from emergency signaling, providing clear communication with dive teams and surface support.

Compact, lightweight, and always ready when needed, the Halcyon 3.3 ft Closed-Circuit DAM is an essential piece of safety equipment that belongs on every dive.
