The Surface Market Buoy (SMB) should be in with you on every dive. Have you ever surfaced from a dive, only to realize your dive boat is so far away that they probably cannot see you? This situation could lead to stress and even panic.
Deploying the DiveAlert SMB will make your more visible in the water. The intense orange and/or yellow is clearly visible to passing boats, so the use of an SMB may also reduce your risk of being struck by a boat while waiting to get picked up. This also applies while you are just beneath the surface, especially while doing your safety stop.
The DiveAlert SMB (surface marker buoy) features closed-circuit (one-way valve) construction, which prevents air spill at surface. Inflate on the surface to attract visual attention or redundant flotation. Inflate at depth to send up as a surface marker. SOLAS reflective tape (Coast Guard approved) across top of SMB creates better visibility day and night. Over-pressure valve (OPV) prevents bursting and easy air dumping. In addition, the deluxe version has safety orange one side and florescent lime/yellow the other side, a filler nozzle for both oral and BC LP hose inflation with a small pocket that will accommodate a finger spool.
Nylon strap handle on top allows for easy attachment of light or slate. 400-Denier poly-urethane coated nylon material, this SMB will last dive after dive without issue.
