The Orange Halcyon Oral-inflate 3.3′ SMB is a 1m long SMB suitable for surface deployment. The SMB is not fitted with a pressure relief valve and, as the name suggests, is made to be inflated by mouth.

When deflated, this small-format SMB fits in a pocket or the Halcyon MC Storage Pak on a Halcyon backplate.

Please note: Due to its dimensions, we do not recommend the 3.3′ SMB as a primary SMB for boat or shore diving in the UK. Halcyon’s primary SMBs that are acceptable to most UK dive skippers include:

• Halcyon Closed Alert Market 6′ SMB
• Halcyon 6′ SLIM Closed Alert Marker SMB
• Halcyon Closed Alert Marker 4.5′ SMB
