These 200# Automatic Wildlife feeders are the best! This maintenance FREE patented Hopper design gives you the flexibility to spin feed in the Fall and Winter months and easily convert it to a protein feeder in the Spring & Summer time. 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. These feeders are great for remote location feeding where access is limited to ATV's and foot access only. Deploy the Boss Buck 200# feeders in those out of the way honey holes for excellent results! NOTICE: Using salt based feed materials/blends through a Boss Buck control system will void the parts warranty! Salt based mineral supplements, such as Big Tine 30-06 mineral blend, will corrode and rust your feeder control box more rapidly than using corn, protein or other non-salt based feeds.
