From my experience all you need is a Foxpro spitfire and perhaps few hand calls. The spitfire e caller holds plenty of calls more than most people will use. Basis calls are cottontail rabbit, jackrabbit, mouse squeak,
distress and canine sounds. As far as hand calls dying rabbits, rubber squeakier (very important), and perhaps a howler. 95 percent of my game is called in with distress sounds. Any thing else is a waste of money. I have traveled in many states hunting predators and from experience this is what works. Don,t be sucked by new and fancy colored calls. The best hand calls that WORK all the time are the Critter Call, Tweety Calls, Green rubber Sceery calls and rubber bulb squeaker. Bobcats,coyotes and fox. If I had only two calls to use it would be bird distress call and cottontail call. Over the years I have found that most animals show themselves within 15 minutes. Few take more than 30 minutes. I have over 60 hand calls and use only 4 of them that work. My Foxpro Fury has over 200 sounds. I only use about 10 sounds. If you need help picking sounds that work just pm me. If you follow my direction you can be a world class predator hunter for under $250.00.
