Standing at a manageable 5'4" high, this 30-gallon unit is easier to fill than traditional spin-cast feeders. Timer and battery are conveniently housed on the side of the hopper in a protective weatherproof casing that is easy to access. Feeder motor is protected by a metal varmintproof cage. Metal feeder feet are included for extra stability. Programmable digital timer allows you to schedule six feedings per day. Customize feed-dispensing times of 1-20 seconds. Operates on a 6-volt battery (not included).
