What are the bowhunting benefits of small-diameter arrows?
Easton ST (Slim Technology) small-diameter arrows are a patented Easton technology. ST enhances the penetrating performance of arrows. Laboratory testing shows that when kinetic energy is held constant, arrow diameter is the determining factor in arrow penetration. With this understanding, Easton engineered ST as the next big advancement in hunting arrows. ST small-diameter arrows provide significant increases in penetration and less wind drift than conventional-diameter carbon arrows, due to its innovative micro-diameter and reduced surface area. The thicker shaft wall design was needed to deliver the correct bowhunting spine sizes, but more importantly, thick-wall design provides increased durability and enhanced kinetic energy for better downrange penetrating power. ST was first introduced on the AXIS arrow, and has since spread into other all-carbon and A/C Easton shafts.
