The Buck Gardner Vocal Varmint Calling Coach is a handy electronic calling coach that aids in your ability to duplicate distress calls while practicing to improve overall hunting performance. This calling coach unit audibly plays back the four basic sounds that enable the hunter to listen to the cadence and length of the notes. The Vocal Varmint also doubles as an electronic predator call. Predators will not be able to resist the distress sounds of the Cottontail, Jackrabbit, Bird, or Coyote Pup. This compact call includes Velcro so that it can be easily attached to the stock or forearm of your gun.
