Last year I got into coyote hunting and purchased a Foxpro X2S. I called in 20 or so coyotes with it over the course of a few months here in Eastern South Dakota with the sounds that came standard. Foxpro has a few good sounds in my opinion, but most of them are what you would expect to hear off of a Primos Alpha Dog or any other 10 year old call. I think the X2S is a great piece of eqiupment, but everytime I hear a Lucky Duck I get a little jealous of their sound library. The Foxpro seems to hold its own in distress sounds, but falls short in the coyote vocal department. Coming into this season now I still find myself wanting some more sounds to add to my call. I understand you can purchase upgraded sounds from Foxpro, MFK, and others. Have any of you ever purchased or used upgraded sound options, which direction did you go? What are my options, I want to hear your thoughts!
