The Halcyon 1M open-cell SMB is a no-frills SMB for the budget-conscious diver. Unlike the closed-cell SMBs this type is open at the bottom, allowing it to be only inflated by exhaled bubbles.

The downside is this type of SMB must have constant tension on the line to prevent it from tipping sideways and spilling the air out.


They are a great option for the diver that hardly ever uses the SMB but must carry it due to local regulations or pure emergencies.
