Halcyon 3.3ft 1m Closed Circuit Diver Alert Marker (DAM) w/ OPV
Halcyon Diver Alert Markers (DAM) enhance diving safety by providing maximum visibility and redundant flotation. The peace of mind that comes from proper preparation is second only to the practical support offered by Halcyon Diver Alert Markers during a separation from the dive team or surface vessel. Halcyon Alert Markers are available in yellow or orange for divers who wish to carry one color to mark position and another to designate emergency situations.
Halcyon offers a variety of Lift Devices and Surface Markers, allowing divers to select the best option for their particular environment. Divers in calm conditions and/or on shallow dives often choose a small Halcyon surface marker so the boat can easily identify their position.
In rough or unpredictable seas divers may carry a slightly larger inflatable, which increases visibility. Open bottom SMBs are very simple designs with a low profile (because they do not need an OPV valve installed); however, these designs are slightly more prone to tipping, which can induce a loss of gas while at the surface. Closed-circuit bags eliminate the risk of gas loss at the surface and provide optional surface floatation but must be filled with a low pressure inflator hose.
