XDeep SMB 140cm Closed Narrow

XDeep SMB 140cm Closed Narrow

The XDeep SMB 140cm Closed Narrow provides a highly visible and reliable signalling solution for all maritime environments. You can easily inflate this surface marker buoy using a standard low-pressure inflator hose.

Furthermore, the integrated over-pressure dump valve prevents damage by releasing excess gas during ascent. This essential safety tool utilises high-quality Nylon 240 dTEX fabric, which is specifically designed for life jackets and signalling equipment.

Additionally, the reflective strip features 3M Scotchlite tape, which carries a prestigious SOLAS maritime visibility certificate. To enhance communication, a clear plastic tube on the side allows you to store small notes or a glow stick.

Because the design includes a large sling underneath, you can attach a spool or reel with total ease. Finally, a small bungee loop keeps the unit neat and tidy during storage in your pocket.

Product Highlights

• High-Visibility Materials: Uses Solas-certified 3M Scotchlite reflective tape to ensure you remain seen in low-light conditions.
• Durable Construction: Features American-made Nylon 240 dTEX for maximum longevity and resistance to the harsh marine environment.
• Easy Inflation: Supports simple filling via a low-pressure hose, ensuring the XDeep SMB remains fully inflated at the surface.
• Safety Features: Includes a reliable over-pressure valve (OPV) to protect the SMB's structural integrity during rapid ascents.
• Note Holder: Provides a dedicated, clear plastic tube for chemical lights or waterproof messages to your surface support.
