Introducing the new React Sight with React Technology exclusively from Trophy Ridge. The React sight utilizes React Technology allowing your sight pins to react to each other or simply put, (sight themselves in). With this sight, you can be sighted in at 20, 30, 40, 50 and 60 yards in less than 10 minutes.Here’s how easy it is:Sight in your 20 yard pin using the tool-less micro windage and elevation adjustments.In order to set the next pin we recommend archers step back to 30 yards and fine tune at that distance before shooting the remaining pins. More experienced archers can sight their second pin in at 30, 40, 50 or even 60 yards.Once you have 2 pins sighted in accurately the rest of your pins will be automatically set, it’s that easy.
