OLED technology provides users with an adjustable display intensity to account for various light conditions. This rangefinder also doubles as a 6x22 magnification monocular with a fully multi-coated lens system to give you a clear view of the target you're ranging. The RX-1600i is equipped with 3 selectable reticles: Plus Point, Duplex, and Duplex with Plus Point.
