Halcyon Big 4.5’ SMB

The Halcyon Big 4.5’ SMB (Surface Marker Buoy) serves as a reliable, 1.4m long closed circuit alert marker in highly visible orange. 

Consequently, this SMB lacks an open bottom; divers inflate it using an inflator hose through the fitted one-way valve connector. 

An integrated pressure-relief valve is built into the design, specifically allowing for safe deployment from significant depths. 

Halcyon SMBs consistently provide maximum visibility and redundant flotation, which actively support diving safety and grant peace of mind.

Safety, Visibility, and Portability

This closed circuit marker is constructed from durable 200 denier nylon, offering an impressive 18kg lift capacity. Furthermore, when completely deflated, this marker conveniently fits into a pocket or the backplate Halcyon MC Storage Pak, optimising portability. 

Halcyon also mark the SMB with Coast Guard approved SOLAS reflective tape, dramatically enhancing surface visibility. You can rely on the quality, as Halcyon offers a Lifetime Warranty on all RF-welded seams, ensuring lasting performance.
