Primos Up ROAR Deer Call is truly a triple threat. It combines 3 of the most effective calls to bring deer in close. It has 2 chambers, an aggressive buck grunt and an estrus bleat, topped off with a wheeze tube to challenge bucks to a fight. The grunt chamber reproduces a deep, resonating aggressive grunt that is made by bucks during the rut. The bleat chamber reproduces a loud estrus bleat made by receptive does. When using these calls in combination you can sound like a buck chasing a hot doe. Other bucks will come running to see what’s causing the Up ROAR.
