MAKING SETUP A CINCH: Trophy Ridge engineers have done something remarkable with the React H5. They developed a mechanical system which automatically adjusts the pin spacing to match the parabolic flight path of your arrows - no matter how fast your particular bow is. All you have to do is set your top pin for 20 yards/meters (using the micro-click gang windage/elevation adjusters), then step back and set a second pin (we suggest the 50 or 60) with the pin gap knob. Once you have 2 pins sighted in accurately, the rest of your pins will automatically be set in perfect 10 yard or meter increments. It is that easy!
