The Rx releases are the prescription for any hardcore bowhunter or target archer. The Rx1 and Rx2 were collectively inspired by World renowned Bowhunter Dr. Randy Ulmer, Champion target archer Michael Braden and were designed by Jerry Carter. They are simply the fastest, quietest and most accurate wrist strap releases sold. The Rx series features a brand new magnetic hook return that closes with a simple squeeze of the finger. This unique self closing, open hook design is perfect for trouble-free shooting from a string loop. They come standard with a premium, fully adjustable leather buckle strap made by Scott. Dr. Ulmer has gone on record to say that he has finally found the ultimate hunting release in the new Rx2! The doctor's orders are to take one Rx in the evening and call the taxidermist in the morning !
