The Carbon ExpressA(R) Maxima(TM) Triad(TM) is a Tri-Spine XSD (Extreme Small Diameter) .166 hunting arrow with performance at its core. Featuring Carbon Expresses exclusive REDZONE(TM) Technology, the Patented three spine arrow shaft creates less than 1/3 the oscillation of single spine arrows and FOUR TIMES THE ACCURACY for easier tuning and unprecedented accuracy. Constructed of ultra-stiff and strong 30-ton carbon, the Triad recovers faster from the bow to reduce oscillation and increase accuracy with shot-after-shot repeatability. Smaller Diameter constructions means thicker walls, more durability, ultimate penetration and knockdown power with significant reduction in crosswind drift. Each package of shafts is a Laser Match Set that are sorted and matched by spine and weight for best-in-class consistency with a spine sorting tolerance +/-.0025 & weight sorting tolerance +/-1.0 grains.
