Its no secret, fish are attracted to both sight and sound. The MAKO Fish Rattle is the coolest way to bring in the big ones. It’s a self contained stainless steel capsule encasing steel balls which can be heard from far away when shaken. The durable belt clip attaches securely on your MAKO stainless steel D ring for easy access. And, the orange cap has a built in magnet to prevent the steel balls from rattling when not in use. You simply remove the orange cap before shaking.
