Built for the bowhunter and the competitive archer, the new RX- FullDraw 5 is the most ballistically advanced archery rangefinder on the market. Using your bows velocity, peep height, your arrow weight and the angles of your shots, it calculates laser-accurate ranges based on your specific gear. The RX- FullDraw 5 accepts an even broader range of velocity inputs, allowing you to input numbers as low as 170 feet per second. You can choose between two modes for viewing arrow obstructions out to a typical distance of 85 yards. It has a setting for ranging in bad weather. When there's moisture in the air, Last Target mode will punch through rain, fog and snow to make sure you get an accurate reading. Pair that with its 6x magnification, bright red OLED display and fast laser engine and you'll see why this rangefinder is guaranteed to give you the advantage that you've been looking for.
