Designed to improve diver safety and surface visibility, this high-visibility Diving Surface Marker Buoy (SMB) helps divers clearly signal their location during ascent and at the surface, especially in open water and drift diving conditions.
Built with a large over-pressure relief valve, the SMB automatically releases expanding air during ascent, reducing the risk of accidental over-inflation and sudden rupture. This safety-focused design makes it particularly suitable for beginner, recreational, and travel divers who want a more controlled and stress-free ascent experience.
The buoy is constructed from durable 210D nylon fabric with TPU coating, reinforced with double-stitched seams for reliable sealing and long-term use. The material provides excellent resistance to wear, abrasion, and repeated inflation cycles, making it dependable for regular scuba and freediving activities.
For quick and flexible deployment, this surface marker buoy supports three inflation methods: oral inflation, second-stage regulator inflation, and low-pressure inflator hose connection. These options allow divers to easily deploy the SMB during safety stops or drift dives without additional tools.
Featuring a bright high-visibility color, reflective strip at the top, printed dive flag pattern, and clear “DIVER BELOW” text, the buoy is designed to be easily spotted by boats and surface teams, even from a distance or in low-light conditions.
An essential piece of diving safety equipment, this inflatable signal tube is ideal for scuba diving, freediving, snorkeling, underwater photography, drift diving, and travel diving—helping divers stay visible, confident, and safer on every dive.
