It also has a headphone jack, molded non-slip grips and a lanyard ring. Operates on three AAA batteries (included) and will automatically shut-off after two minutes at idle to preserve battery life. There is an LED indicator light to tell you if the unit is on or off. Interchangeable sound sticks allow you to easily convert your Mini Phantom for hunting a wide range of species.
