HQ Diving Yellow Emergency SMB – Compact Surface Marker Buoy
Stay highly visible and clearly signal your position with the HQ Diving Yellow Emergency SMB – Compact Surface Marker Buoy. Designed for recreational, technical and decompression diving, this 110 cm high-visibility SMB provides a clear surface marker for boat crews, dive operators and other water users.
The bright fluorescent yellow colour is easy to identify at the surface, while the dual-purpose design features large DIVER BELOW and EMERGENCY markings for clear communication when visibility and rapid recognition matter.
Measuring 110cm x 12cm, the buoy delivers excellent visibility while remaining compact enough to roll down for storage in a BCD pocket, technical diving shorts or equipment pouch.
High-Visibility Emergency SMB for Scuba Diving
Whether you’re completing a safety stop, drifting offshore, conducting decompression procedures or signalling for assistance, this compact surface marker buoy gives you a highly visible reference at the surface.
The integrated inflation system provides convenient deployment from depth or at the surface. An over-pressure relief valve allows expanding gas to escape during ascent, helping prevent excessive pressure inside the buoy, while the quick-release dump makes deflation fast and easy after the dive.
An integrated attachment point allows secure connection to most finger spools and dive reels, making the SMB suitable for recreational divers through to experienced technical divers.
