I also have the Spitfire, and I'm not sure what to think. It seems to work flawlessly, is plenty loud for me, but I rarely, if ever, seem to call in a coyote with it. I realize I'm pretty new to coyote hunting, but I saw a thread the other day where several others were saying how much more game they called in using a "different" caller, than they ever did with their Foxpro. They were talking about the actual Foxpro sounds not sounding as good as this "other" caller!?!
I know that I'm still learning when it comes to set-ups, keeping still, approaching the stand, using the wind..........but I've hunted many, many, many, many, many stands where I've not even called one in (to my knowledge). Just got me wondering if I should consider changing up some sounds or something.......
