The Mini Phantom Speaker easily clips onto your Mini Phantom Digital Call or can be set a distance away from the Call. It amplifies and enhances the sounds. You can now attract game from further away and distance yourself from the source of the sound, enjoying more success in the field. This speaker comes with an attachment cord and a 25″ cord. You can set the speaker as far away as 300″ with additional 60″ sections of wire (sold separately; see accessory section-wire lengths work on both pro and mini calls). It is water resistant, features an LED power indicator, and runs on 4 AAA batteries (not included).
