The Callaway 250+ Laser Rangefinder supplies precise distance measurements, including slope adjusted distance. It sports P.A.T with Pulse Technology, which provides the golfer with a short vibration to confirm the laser has locked on to the pin. You can lock on to the pin-up to 300 yards away! The rangefinder is super lightweight and ultra-compact for easy use. Integrated magnets allow for quick access and storage on golf carts.
