The Halcyon Diver Alert Markers are closed circuit surface marker buoys. SMBs are essential safety equipment in high vis colours, every diver should carry. With 1.4m (4.5ft) length, the SMB has a lift capacity of 40lb (18kg). For your safety, it is also fitted with a Coast Guard approved SOLAS reflector.
The Halcyon D.A.M.s have a No-Lock connector to easily fill them at depth orally or with your LP inflator. The integrated pressure-relief valve lets out excess air during ascent. You can store them in the Halcyon Storage Pak or the Halcyon Bellows Pocket.
