The Razor Delayed Surface Marker Buoy (DSMB) is a compact, durable safety accessory for sidemount and open-water divers. It improves surface visibility during drift, night or technical dives and when separated from the boat.

Available sizes: 150 cm × 15 cm and 180 cm × 15 cm.

• High visibility: Two-sided color panels with reflective tape on both sides for improved detection in varying conditions.
• Inflation options: Plastic inflation valve and open bottom for second-stage inflation; compatible with wing LPI hose or second stage for initial or additional inflation.
• Overpressure release valve: Prevents bursting and allows controlled deflation after use.
• Secure closure: Bungee and hook-and-loop (Velcro) closing with D-ring for double fixation to prevent unrolling and reduce packed volume.
• Weighted base: Lead weight at the bottom keeps the buoy upright on the surface.
• Attachment points: D-rings on top and bottom for line or clip attachment.

Note: Two color combinations are available to suit regional preferences or to convey different signals during technical dives.
