The Carbon Express 58056 LaunchPad LED Lighted Moon Nock is the perfect combination of weight, brightness and battery life. Top shooters know that nocks are an important component of consistent, accurate arrow flight. This insight led Carbon Express engineers to develop the patent pending LaunchPad Precision Illuminated Nock. The release activated, high visibility LED includes a long-life battery. It features precise contact points for controlled arrow release; an aligned nock barrel for true arrow flight; concentric design to center the nock in the arrow shaft for consistent performance. Its lightweight design does not reduce arrow front of center (FOC). The 58056 fits all Carbon Express carbon hunting arrows and most other standard sized carbon hunting arrows. To gain the advantage in the field, you need the best equipment, which is why so many hunters, competitors and enthusiasts insist on the Carbon Express brand. It’s a simple fact: Arrows with consistent spines ensure tighter groupings downrange and make consistently better, more accurate shooters. Carbon Express uses innovative technology and the highest grade of carbon fiber to produce the most consistent arrow spines in the industry. Unlike other manufactures, Carbon Express laser sorts its premium hunting shafts to ensure all the arrows in each set have the same spine tolerance and provides the straightness tolerance that are maximum measurements, not merely averages. If you have a passion to shoot better, Carbon Express will continue to develop unparalleled advancements in accuracy, recovery and performance to provide the public with the finest arrows, broad heads, crossbows and cross bolts, as well as archery and cross bolt accessories.
