Ultimate Hunting Performance - Redefining Accuracy & Penetration

The Carbon Express® Maxima™ Triad™ is a Tri-Spine XSD (Extra Small Diameter) .166 hunting arrow with performance at its core. Featuring Carbon Expresses exclusive REDZONE™ 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 construction means thicker walls, more durability, decreased wind resistance/crosswind impact and exceptional penetration with +/-.002” Real Straightness. 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.
