I have quite a few coyotes running around my deer hunting property so I want to get rid of them. I will probably only hunt 10x per year. I would like to use an electronic call but don't want to pay an arm and a leg. Most of my hunting will be done over 200x100 yd fields using a .223. I will only be using it for coyote hunting. Is there a big difference between the cheap (under $50) call and the expensive calls? I like the idea of a remote caller. Can I get a good one for under $150? Any recommendations? Thanks for all your input.
