Hi, Yep...I too have a fx-3 it is great called in dogs, cats, hawks, even a couple eagles. I am going to try it soon on raccoon. And then this spring on bear so...yep good call !! BUT ....... battery life is the down side when it is cold out...and when it is really cold like about 0 plan on having a bunch in the truck. I am looking into building my own power source, like a sealed lead acid battery and hard wire it in. Then you charge it from site to site feel free writing me, I can put in contact with someone who knows how.
Other wise....get it you will be happy.
