This is a hard vibrating blade bait, a type of rattle bait though in metal. Astro Vibe has something extra, a hollow rattle chamber in the belly, this gives Astro Vibe another frequency of attraction. The hollow rattle chamber belly is made in UV-coated plastic which makes it glow up in any weather! Astro Vibe sinks fast and can be fished as deep as possible, even straight vertical, but thanks to the buoyancy in the bait, can be fished fast and shallow. A very versatile bait that time and time again proves invaluable in the tackle box!
