I like and have an excaliber the are extreamly acuate and for giving ( dry fired) not recomended but will not fly apart like compunds. I have taken 4 deer and one fisher that tried to get in the same tree with me while I was deer hunting .
They may be alittle higher than your price range but I don't know how the prices are down in the States.
When calling coyotes, more often than not they will circle on a target they are
coming into and approach from the downwind side. Presumably they do this in
order to align what they smell, with what they are hearing.
This means that you should always have your downwind side camouflaged and have
an open shooting lane. If the area is heavily covered the coyote could come in
take a look and be gone, with you none the wiser.
