The Evidence is designed for the most demanding hunter in mind. Manufactured to a .001 straightness and combined with Bloodsport's proprietary Rugged Wrap construction, the Evidence provides unparalleled flight and penetration at even the longest distances. Bloodsport's Rugged Wrap construction process provides a much thicker wall than competing shafts. Combining micro-diameter shaft with (patent pending) Reliable Outsert Technology (R.O.C.) System, the Evidence takes arrow strength and toughness to a level never achieved in this category before now. Experience the Evidence for yourself. Evidence Arrows come equipped with Blood Ring Certain Shot Technology that will reveal what kind of hit was made using the age-old logic of blood types, shown on the white Blood Ring panel after contact with your target has been made.
