Halcyon 1.0m Closed Circuit D.A.M. (SMB)
The Halcyon Diver Alert Markers are closed circuit surface marker buoys, which are used to signal your position underwater. SMBs are essential safety equipment every diver should carry. Due to their bright colours, orange or yellow, they are highly visible. With 1m (3.3ft) length, the SMB has a lift capacity of 6lb (2.7kg). For an even better visibility, it is also fitted with a SOLAS reflector.
They 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.
