The Primos Hunting High Roller Call easily produces the rolling, fluttering whistle of the pintail. This Game Call by Primos Hunting features a roller built into the High Roller™ that makes the whistle flutter automatically just like the whistle of ducks. The Primos Hunting High Roller Duck Call can also reproduce the mallard drake grunt and whistle of the widgeon and teal. The Primos Hunting High Roller Pintail Call allows hunters to call ducks with convenience.
