DIRZone SMB 122cm with Duckbill, Small OPV

DIRZone Alert Marker 122cm with Duckbill & Small OPV

The DIRZone Alert Marker 122cm is a high-visibility surface marker buoy designed for both recreational and technical divers who require a reliable signalling device with easy deployment and compact storage. At 122cm, it offers excellent visibility on the surface while maintaining portability and convenience.

Equipped with a duckbill-style over-pressure valve (OPV), this SMB can safely release expanding air during ascent, protecting it from over-inflation. The special small OPV design allows the buoy to roll up compactly for easy stowage without compromising performance.

Inflation is straightforward thanks to the inline inlet valve, which supports inflation via a BCD adapter or by purging a regulator. A sturdy stainless steel D-ring provides a secure attachment point for a spool or reel, ensuring reliable deployment in the field.

With a lift capacity of 71N (16lb), the DIRZone Alert Marker is ideal for safety stops, drift diving, and emergency surface signalling. Its durable construction and thoughtful design make it a dependable addition to any diver’s safety kit.
