The 6x20 RX-650 Laser Rangefinder from Leupold combines a Class 1 eye-safe IR laser with a useful fully multicoated monocular to create an effective and waterproof ranging system. With a wide 366' field of view at 1000 yd and a ranging accuracy of ±1 yd out to 125 yds, the rangefinder provides spot or continuous line-of-sight ranging, and when used on golf courses utilizing prism technology the RX-650 locks onto the prism and freezes the distance. The intuitive one hand operation enables quick activation and operation. The RX-650 is powered by a single included CR2 battery and an in-view status indicator continuously shows the power level.
