This Halcyon Diver Alert Marker is a closed circuit surface marker buoy, which can be used to signal your position underwater. SMBs are essential safety equipment every diver should carry. Due to the bright orange colour, it is highly visible. With 1.8m (4.5ft) length, the SMB has an optimal visibility on the surface, even in high swell. For your safety, it is also fitted with Coast Guard approved SOLAS reflectors.
The Halcyon D.A.M. has a No-Lock connector to easily fill it at depth orally or with your LP inflator. The integrated pressure-relief valve lets out excess air during ascent
