Yes, the remote callers do work as good as they claim,my Foxpro FX3 works father than you need it to.I usally set up within 70yards or less anyway the terrain here in Kentucky is a little hilly.I have tried it in my driveway up to 400 yards,but I dont have any need to call that far away,even in the woods,through barn walls it works great.call them in close and kill'em.
