Grab the handle, pull the feeder out of the box, add some feed, and you are ready start feeding. This easy to use feeder comes assembled with batteries and is simple to program. The digital timer can be set to release feed up to four times per day for one to 20 seconds at a time. The metal spin plate evenly spreads feed preventing a pile of deer feed from forming under the feeder. Four AA batteries supply enough power for four months of field life.
