The Scubapro Orange Nylon 210D SMB is a compact surface marker buoy designed for scuba diving and underwater signaling. It folds into a small package for easy stowage during a dive and expands to 42 in (3.5 ft) at the surface to mark position and improve visibility for divers and support vessels. Made from rugged 210D nylon with sealed bottom, metal inflator, and a 42 mm exhaust valve, the SMB offers reliable inflation and venting. A stainless steel D-ring and bungee loop provide attachment options for accessories and gear such as lights or reels.

Designed for recreational scuba diving, the SMB is compatible with standard signaling practices and serves as a dependable surface marker in open-water conditions.
