The Halcyon Closed 3.3’ SMB is a closed circuit 1m long alert marker in orange. The SMB does not have an open bottom and is designed to be inflated by using an inflator hose through the fitted one-way valve connector.
The SMB has an integrated pressure-relief valve, allowing them to be deployed from depth. When deflated it fits in a pocket or backplate Halcyon MC Storage Pak.
Halcyon SMB provides maximum visibility and redundant flotation to support diving safety and peace of mind.
Please Note: Due to it’s short length and width, the 3.3′ SMB is not recommended as a primary SMB for UK boat diving. Halcyon’s primary SMB’s acceptable to most UK dive skippers are:
- Halcyon Closed Alert Market 6′ SMB
- Halcyon 6′ SLIM Closed Alert Marker SMB
- Halcyon Closed Alert Marker 4.5′ SMB
