Halcyon Diver’s Alert Markers (DAMs) are essential safety tools for every diver, offering reliable surface visibility and, in larger models, redundant lift in emergencies. Built from durable 200 denier nylon with RF-welded seams, each DAM features a closed-circuit design that prevents accidental gas loss, ensuring a lasting signal even in rough conditions.
Available Size and Color Options
- • Standard 3.3' (1 m) – Compact and easy to stow, providing 2.7 kg / 6 lb of lift. Ideal for recreational divers.
- • Big 4.5' (1.4 m) – Taller profile with 18 kg / 40 lb of lift, marked with SOLAS reflective tape for enhanced visibility.
- • Super Big 6' (1.8 m, 25 cm wide) – Full-size DAM with 23.6 kg / 52 lb of lift, excellent for long-range signaling or light-duty recovery.
- • Super Slim 6’6" (1.8 m, 15 cm wide) – Lightweight option with 5.5 kg / 12 lb of lift, excellent visibility without extra bulk.
All models are equipped with Halcyon’s No-Lock® connector for oral or LP hose inflation, and an integrated over-pressure relief valve for safe deployment from depth. When deflated, they pack small enough to fit in a Halcyon thigh pocket or MC Storage Pak.
