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