HHA Sports Optimizer Sight Series continues to ride the wave of success after receiving the Bowhunting World and Archery Business Reader's Choice Award for a 4th consecutive season! HHA Sports Totally Tooless micro adjust proved to be a big hit with consumers and allowed them to throw away Allen wrench sets when sighting in. The HHA Optimizer Lite Ultra lived up to the hype with its' unique tape system will continue to revolutionize adjustable sights. A 2nd generation slider sight, a yardage dial replaces the traditional elevation arm for making precise yardage adjustments. Sighting in at 20 and 60 yard allows you to determine your customized yardage scale marked in one yard increments for pin point accuracy. New for 2008 we've added that same technology to our Optimizer Lite Series which is sure to make our legion of loyal followers happy. The system will be included in all HHA 5000, 5500, 5200X Series sights and can be purchased seperately for current sight owners.
