Carbon Express Maxima Red SD Shafts (1/2dz)

Maxima RED SD arrows is a breakthrough in controlling dynamic spine in a smaller diameter and further stacking the odds in a hunter’s favor giving them the ultimate combination of accuracy, penetration, and less wind drift. Managing the enemy of accuracy, dynamic spine the high-tech carbon design of Maxima RED SD arrows feature stiffer distal ends to contain the arrow’s flex to the RED ZONE®. Utilizing Carbon Express's exclusive Tri-Spine 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. Small diameter .203” Maxima Red SD delivers improved penetration and reduces wind-drift which enables more accurate shots at longer distances. Premium Carbon Express Half-Out inserts (each 54 grains), Bull Dog Nock Collars, and Launch Pad Nocks are all included. Each group of arrows is spine selection sorted to a tolerance of +/- 0.0025-inch and eight sorting to within +/- 1.0 grains. Features: Tri-Spine/RED ZONE Technology – Patented 3 spine arrow shaft with less than 1/3 the oscillation vs single spine arrow & FOUR TIMES the ACCURACY. SD – Small Diameter .203” ID, maximum kinetic energy and greater penetration with less crosswind drift. BuffTuff Plus – Patented outer layer construction on the front 1/3 or 100% high modulus carbon weave for excellent strength & spine consistency. BuffTuff – Patented outer layer construction on the middle 1/3 that provides the world’s toughest and quietest carbon arrow finish plus makes it easier to remove from targets. Diamond Weave – Patented outer layer construction on the back 1/3 that provides ultimate stiffness and unparalleled spine technology. BullDog Nock Collars – Exclusive feature made of aircraft grade aluminum designed to prevent rear impact damage Laser Match Set – Pack sets are sorted & matched by spine and weight for best-in-class consistency. Spine sorting tolerance +/- .0025” & Weight sorting tolerance +/- 1.0 grains +/- .002 Real Straightness – Laser checked for straightness to remarkable 1/10,000 of an inch, our straightness standards are set as a max not an average like competitors. Launchpad Precision Nocks – Controlled arrow release and integrated shaft alignment for more consistent accuracy.
