At last, for those seeking the absolute easiest call on the market, the Right-On calls are the solution. Available in a set or by the unit, each call has been conceived to reproduce only one precise sound of male or female moose. Place your lips right before the pre-set o-ring, press very slightly on the strip with your upper lip and blow. Child s play. Vary the tone using your hands to form a sound chamber or use the megaphone to increase volume to get greater distance.
