The IQ™ Micro Bowsight's revolutionary Retina Lock™ Alignment Technology will dramatically extend your effective range! Most bow hunters are confident shooting at shorter ranges. But, get out to 40 yards or beyond and they lack consistency. This is because of mis-alignment due to bow torque or inconsistent anchor. It doesn't take much. A 1/4" translates to a 10 inch miss at 40 yards. That's about to change! IQ Bowsights revolutionary Retina Lock Alignment Technology puts you in perfect alignment for every shot. It's easy to use and you'll instantly be shooting short range groups at long range distances! IQ is simply the best hunting sight on the market!
