HHA Optimizer Lite X 5519 Features The HHA Optimizer Lite X 5519 uses HHA s R.D.S. technology to deliver single pin sighting with a yardage tape calibrated in 5 yard increments letting the archer dial in a precise setting with a quick turn of the adjustment dial. A smooth lever action moves the sight housing through its full range with minimal effort supporting accuracy from 20 out to 80 yards. The sight is machined from aluminum into a compact 1 5/8 inch housing keeping the unit lightweight at roughly 8 ounces while maintaining the rigidity needed for consistent pin placement shot after shot. An infinite adjust slotted side bracket gives the archer additional fine tuning when mounting the sight to the riser. A built in leveling bubble helps the archer confirm the bow is held perfectly vertical before releasing reducing left to right error caused by bow cant. The sight ships with 3 feet of .019 fiber optic pin material which gathers ambient light for a bright easily visible aiming point in a range of lighting conditions. An optional mechanical rheostat lets the archer manually adjust pin brightness while water resistant tapes keep the yardage markings legible in wet hunting conditions. Compatible with HHA s Lens Kit B and Blue Burst light accessories the Optimizer Lite X 5519 is built for bowhunters who want fast repeatable single pin precision in the field.
