Bullet Drop-calibrated ranging system --This allows precise holdovers to 800 meters without mechanical adjustments, with built-in target sizing for quick range estimation

Strengths: The TA11E delivers unmatched durability with crystal-clear glass quality that exceeds most LPVOs at similar price points.
