Incorporating all the elements of the best-selling Target Pro Grip shaft, the Pro Grip Spin is a polycarbonate spinning shaft that features Hydrogel technology to produce a smooth, consistent movement between the elements. The spinning motion reduces dart deflections to improve scoring and consistancy. The Target Pro Grip Spins are made from a specially formulated nylon compound to ensure durability. Each Pro Grip shaft is also supplied with a Target Pro Grip ring for added flight grip.
