The Boss Buck All-In Auto System Feeder is the best! This maintenance free patented auto system feeder gives you the flexibility to gravity feed protein in the Spring & Summer and converts over to an automatic feeding system in the fall and winter months. This is the most user friendly, versatile wildlife feeder system on the market today. Our double walled hatch lid tops this unit off in style, and function. It allows the hopper system to breathe thus eliminating condensation while achieving ambient temperature faster than steel or fiberglass feeders. This versatile feeder is great for remote location feeding where access is limited to ATV's and foot access only.
