Product Information
The Scubapro SMB Orange Nylon 210D (3.5 ft) is a compact, foldable surface marker buoy for scuba divers who need to mark their position at the surface, built from 210D nylon with HF welded seams and a sealed bottom and fitted with a metal inflator and a 42 mm exhaust valve. The 3.5 ft size measures 42 in / 104 cm long by 6 in / 16 cm wide and weighs 0.3858 lb, and it folds into a small package for easy stowing while diving.
Who it is for
This is a signaling tool for recreational divers who want a high visibility orange marker that stays out of the way during the dive and deploys quickly once they reach the surface, so boat crews and support vessels can see them. The plastic D-ring on top accepts a flashlight. The larger 4.5 ft size is a professional grade version with a double inflation system and one way integrated valve, and Scubapro lists it as usable with an LPI/BCD hose.
