Managing how an arrow flexes in flight (Dynamic Spine) which is the key to arrow accuracy, and no one does a better job at this than Carbon Express®. The Maxima RED® is a breakthrough in controlling Dynamic Spine. The high-tech carbon design has stiffer ends to contain the arrow’s flex to the RED ZONE®. The RED ZONE is the section of the arrow shaft engineered to contain Dynamic Spine and make a broadhead shoot more consistently. Containing arrow flex to the RED ZONE provides a next-level of hunting performance because broadheads exaggerate the effect of arrow flexing in flight and act like “wings” on the front of the arrow. By reducing arrow flex in the front of the shaft, the Maxima RED® makes broadheads shoot tighter groups and provides overall improved hunting performance. Utilizing Tri-Spine REDZONE Technology to control the center section of the arrow and by doing so creates more consistent arrow flight with 4X the accuracy of traditional single spine arrows. Contain the enemy of accuracy with the Maxima RED® —the best mid-weight hunting arrow ever.
