I have used FoxPro calls since I was 14. I am now 31 now and have used the FREQ on 5 different trips to properties containing VERY EDUCATED coyotes. The FREQ Call offers something different. The sounds produced are so crisp and clear that often we find it hard distinguishing the call from actual coyotes. Historically, these educated spots have left me with a 25% success rate. I’m now 7 coyotes dead for 8 stands, having called in a total of 12 coyotes. My old calls will no longer be anything more than dust collectors! I’m sticking with a call that has “FREQuencies that kill FREQuently!!”
