Compact, convenient, and easy to use, this handheld underwater signaling device is sure to get your dive buddy's attention — give it a good shake and its loud rattling will turn heads. Magnetic end-stopper keeps the shaker from rattling when you need to keep quiet. Attach it to your buoyancy compensator device (BCD) with the included clip. Backed by a 1-year manufacturer's limited warranty. Driven to constantly innovate and improve the diving experience, SCUBAPRO builds equipment for the work, sport, and lifestyle of people whose passion is found below the surface.
