Or it could be what I've said since every Tom, Dick and Harry started making a call and every year coming up with a "NEW DISCOVERY" a "NEW SOUND".. like "clicking'', "Growling" yada yada yada. The call craze has gone crazy. You scare more deer than you attract. Scout, discover, decide a plan of attack, get in your stand and shut up for the most part. You'll see a lot more unalerted deer at point blank. A simple grunt or3 if a deer is passing out of range, or the gentle tickle of a rattle box if that doesn't work. Otherwise shut up.
