I personally scout for deer in the same manner I hunt; with camo and scent free. If you think about it......why go all out when you hunt and not when you scout? Deer know human scent as danger. You can minimize this by scouting like you deer hunt...IMO
I even hang my stands out for a month before I hang them along with spraying a good scent eliminator.
All my opinion, but I try to increase my odds of seeing that wall hanger.
