This professional grade SMB (surface marker buoy) features a double inflation system with a one way integrated valve, making it easy to operate one-handed. The buoy is constructed of durable 210D nylon with HF welded seams. There’s a 40mm stainless D-ring and bungee loop on the lower end, with a plastic D-ring on top for a flashlight.
 
The 180cm size includes a SOLAS reflective stripe on top guarantees high visibility at night or in harsh conditions.
