This new standard of tolerance is called Hidden Insert Technology or HIT for short. HIT was originally designed to fit the next generation, small diameter Easton Slim Technology (or ST for short) arrows that are built for more penetration and better durability. Due to the new small circumference design, standard lipped inserts would no longer be compatible. HIT was engineered to fit up inside the arrow shaft, hidden from view. HIT gives automatic broadhead alignment because the broadhead shank aligns directly against the shaft wall for easy, no fuss broadhead set up. Perfectly aligned broadheads mean more accuracy and tighter broadhead groups. HIT and ST combine to form the next great advancement in hunting arrows and more accuracy, durability & penetration than standard carbon arrows. HIT inserts will only install into Axis shaft models - ST Axis Full Metal Jacket, ST Axis, ST Axis Realtree APG, ST Axis Mossy Oak Obsession, ST Axis Junior, A/C Super Slim and Beman MFX Team Realtree and Classic MFX shafts. The HIT insert comes factory direct with all of these shafts, ready to install.
