Leupold’s high performance DNA (Digitally eNhanced Accuracy) engine with advanced infrared laser technology provides faster measurements with increased accuracy. PinHunter 3 technology increases the pulse rate of the rangefinder which ignores user movement to identify the pin, while the audible Prism Lock lets you know you’re locked on target. The intelligent Flag Lock Technology identifies the pin from the obstacles around it, like trees and bushes, and uses the information to accurately locate and lock on to the pin.
