I think to many miss out on too many possibilities by limiting themselves to a single call. You would be wise to invest in at least, again, at least one of every call. One particular gobbler might react to a pot call and ignore a box call while another might react to a push button box call and not a pot call and another a diaghram. Turkeys are as individual as people and you might walk by many turkeys by limiting yourself to one call...

By far the easiest call to use is the push/pull button box calls and have been responsible for many turkeys being harvested. Todays calls you can get to mount on your barrel for close calling. This calls will work but don't quite have the calling ability of a box or pot call.

Again, limiting yourself to one call will work, but you'll miss out on alot of turkeys....grab yourself several different calls and practice.
