Brad,
Well yes, sorta. Although I don't have at the present time a Zepp Rattler I have ever intention to get one. Several years ago met Mark Zepp and we talked about coyote hunting and our experiences. If first impressions mean anything I believe Mark is a great guy. He has a passion for callng coyotes and has vast knowledge about coyotes. He is someone I would do business with and would even like to hunt with sometime. I've seen and heard the Rattler in action from Marks new video Callin' Coyotes with Mark Zepp and some of his friends. The Rattler has the sound qualities that I look for in a call and I'm sure once I get one it will be a coyote calling machine. I have seen prototypes of the calls Mark is selling. Eddie Hawkins, Marks hunting partner, showed us the calls prior to their release for sale. He also gave a little calling sequence with the calls in the parking lot, which got responses from the local dogs. I believe Mark makes quality products, both calls and video. I have the video and reccommend it highly and I expect the same quality from the calls.
