RE: Always from downwind??
retro fit a weasel ball, you can also add a robo duk remote to turn it on and off, which helps save batt life here in winter.
I' d recommend setting up cross wind, picture a line running from the downwind side to the caller, where you aren' t sitting, and you would be perpendicular to that line.
most callers that are busted here abouts are having preds come straight into them.
you don' t set up your bow stand so you get a straight on shot do you?
If you want to be a better pred hunter start hunting them with a bow and the rifle/shotgun/pistol/ blackpowder thing is simplified.
have fun
