Halcyon’s Diver’s Alert Markers A.K.A Surface Marker Buoys

Halcyon's series of Diver Alert Markers provide maximum visibility and redundant flotation at the surface

Open water divers should always carry a marker buoy they can send up in the event of separation from buddy, primary group, or boat  

Our European customers have been requesting a safety-yellow variation of our Diver Alert Markers– it is common to expect or require both yellow and orange markers when diving off of a charter in some countries. In response, Halcyon is now making the small closed-circuit DAM in florescent yellow.

In addition to the yellow 3.3' dam, Halcyon is introducing a completely open circuit alert marker that will sell in a two-pack with one yellow and one orange marker.

The new markers are 4.5' (1.37m) long, are an open-bottom design (not baffled, like the semi-closed DAM).
