If you're going to set your buck out in a field, I would suggest keeping it facing away from the woods. (that lets other bucks know the field is safe, if he's facing the woods that might indicate danger to other deer looking to come out and he's ready to head back into the woods.)
Also don't use any scents the first time around, make sure you spray the decoy really good with 99% (ScentAway) that's a clean setup, if your Buck sees your decoy it'll come out but if it smells what might be a superior buck it may not come out.
the results from the clean setup will determine what you should do next.
