The MAD R.I.P. Yelper is the next level of innovation in mouth calling technology. Designed by 2X Grand National Champion Ricky Joe Bishop, the R.I.P. Yelper utilizes a unique integrated mouth call design. Built on a small frame by Ricky himself, he has developed a special layering of latex not used in traditional mouth call diaphragms. Utilizing pumped air to activate the diaphragm, you can achieve mouth call sounds without putting a call in your mouth. Lots of turkey hunters cannot use a diaphragm mouth call so this is the next best thing. From sweet competition-quality yelps to aggressive cuts and clucks, the R.I.P. Yelper is as easy and realistic as it gets.
