The DIRZone SMB 180cm CC PRO is a premium high-visibility closed-circuit surface marker buoy (SMB) designed for recreational, technical, and CCR divers who require maximum visibility and reliable surface signalling. Standing 180cm tall, it provides an enhanced visual reference for dive boats and surface support, particularly in rough seas or challenging conditions.
With a lift capacity of 86N (19lb), the SMB offers excellent buoyancy and stability on the surface, making it ideal for decompression stops, drift diving, and technical diving operations.
The CC PRO features an inline inlet valve that enables quick 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 to suit different equipment configurations and situations.
An integrated over-pressure valve (OPV) automatically releases excess expanding air during ascent, helping to prevent over-inflation and protecting the SMB from damage. Its robust construction is designed for repeated use while remaining compact enough to roll and stow efficiently.
Available in high-visibility Orange and Yellow, the DIRZone SMB 180cm CC PRO is easy to spot at distance. A durable stainless steel D-ring provides a secure attachment point for a spool or reel, ensuring dependable deployment whenever required.
Whether you're conducting safety stops, technical decompression, or offshore drift dives, the DIRZone SMB 180cm CC PRO is an essential piece of safety equipment for any diver.
