The Moultrie All-In-One Series Feeder requires no assembly! This item has a digital timer that can program up to 4 different feed times a day, and customize feed dispense times between 1-20 seconds. This series has a metal spin plate and 5-gallon plastic bucket. The built-in funnel design keeps food from trapping on the bottom and sides of the bucket. The series has a test button for easy set up, and the capability to attach a solar panel (not included; only compatible with rechargeable batteries). Four AA batteries are included, and the efficiency and battery design was created to allow for double run time, providing up to 4 months of field life.
