React Technology is the fastest and most efficient technology when sighting in a bow for the first time. In a mere 10 minutes or less, you can have your bow dead-on from 20 to 100+ yards. For 2022, Trophy Ridge has upped the ante with the new Digital React sights powered by Trophy Tech, the muscle behind Trophy Ridges technology. This model is designed specifically for the new Matthews Archery Bow Risers with BRIDGE-LOCK technology.
