Enjoy the ability to throw numerous presentations with the Easybird® Auto-Feed 6-Packer (sold separately) and the Oscillating Base. The 6-Packer provides hours of enjoyment and makes target shooting a breeze with its adjustable throwing ranges, smooth cycle auto-feeding and 150-clay magazines. The Oscillating Base has two arc settings: one at 45 degrees, and another at 34.28 degrees for ATA competition. It also comes with an on/off switch to convert from stationary to angling targets. Both units run off a standard 12-volt battery (deep cycle recommended).
