The Black Magic Vibra Shaft is the ideal nighttime spinnerbait. It has the patented Vibra-Shaft tapered wire that transfers all the vibration to the tip of the wire where the blades are. The single Colorado blades on it are specially made for this bait. They have a deeper cup in them than standard spinnerbaits. They have a size bigger blade on them than the standard weight size for a Colorado spinnerbait. With the deeper cup blade that is one size bigger and the Vibra- Shaft wire, you get a great nighttime spinnerbait that is going to put off a lot of vibration at a much slower controllable speed. The Black Magic Vibra-Shaft is unmatched in water displacement. Moving more water with less effort makes a great spinnerbait. That’s what you feel when you reel the bait back in. If it makes it that far!
