The Buttolo Deer Call imitates all of the major calls of a roe deer. The call is easy to master in one hand and is fantastic as a call for beginners. To use take the rubber ball in your hand so that the thumb lies in the middle of the top. A slight pressure is sufficient to produce the most natural mating calling of the roe. To produce the terror cry, press with the thumb quickly but moderately till it reaches the bottom of the rubber ball. Also deadly on Muntjac.
