Nikon COOLSHOT 20i GIII Rangefinder with 6x Magnification and Lightweight DesignWhen it comes to club selection, knowing the distance of your shot is everything. The lightweight, compact Nikon COOLSHOT 20i GIII gives you both actual distance and slope adjusted measurements to account for distance with uphill or downhill shots rain or shine. Measure up to 800 yards within 2 yards of accuracy. Reliably target the flagstick with First Target Priority mode, and get a clear confirmation vibration with LOCKED ON QUAKE when you hit it.
