Surface Marker Buoys

Surface Marker Buoys (SMBs) provide divers with a highly visible way to mark their position at the surface or during an ascent. Whether used for recreational diving, technical diving, public safety diving, or dive team operations, a dependable surface marker buoy is an important piece of dive safety equipment.

US Water Rescue offers a selection of surface marker buoys, delayed surface marker buoys (DSMBs), diver alert markers, and inflatable dive markers designed for visibility, reliable deployment, and compact storage. Available designs may include open-bottom and closed-circuit models, oral and low-pressure inflator options, over-pressure relief valves, and high-visibility or reflective materials.

Choose the appropriate SMB for surface signaling, marking a diver's location, deployment from depth, decompression stops, drift diving, or communicating with surface support.
