Trophy Ridge sets a new standard for single pin bow sights with the React One Pro Dovetail. Faster and more precise than adjustable sights of a lesser quality, the React One Pro incorporates many features from top-of-the-line target sights, and ensures consistently high performance hunt after hunt. The sight comes equipped with Trophy Ridge’s advanced React Technology, which automatically sights in the remaining indicators after just 2 yardage adjustments to deliver dead-on accuracy. Adjustments to windage and elevation can be made without the use of tools, and second and third axis leveling allows you to hone your accuracy at longer ranges and extreme angles via the integrated adjustment knobs. In addition, the React One Pro mounts via dovetail, and a 5-poisition dovetail allows for more fine-tuning.
