DIRZone SMB120 cm CC Pro

DIRZone SMB 120cm CC PRO Closed-Circuit Surface Marker Buoy

The DIRZone SMB 120cm CC PRO is a premium high-visibility closed-circuit surface marker buoy (SMB) designed for recreational, technical, and CCR divers who demand reliable surface signalling and robust construction. Its 120cm length provides excellent visibility on the surface, helping dive boats and support teams locate divers more easily in a variety of sea conditions.

Built for versatility, the CC PRO features an inline inlet valve that allows rapid inflation using a low-pressure BCD inflator hose. It can also be inflated orally or by purging a regulator into the base, giving divers multiple deployment options depending on their equipment configuration and diving situation.

An integrated over-pressure valve (OPV) automatically vents expanding air during ascent, helping to prevent over-inflation and potential damage while maintaining the buoy's performance. Some versions feature a compact OPV design, allowing the SMB to roll down smaller for convenient storage.

Manufactured in high-visibility colours including Orange, Yellow, and Pink, the DIRZone CC PRO offers excellent surface recognition in a wide range of conditions. A durable stainless steel D-ring provides a secure attachment point for a spool or reel, making deployment straightforward and reliable.

Whether used for safety stops, drift diving, technical decompression, or open water ascents, the DIRZone SMB 120cm CC PRO is an essential piece of safety equipment for every diver's kit.
