I agree the skunk scent is only there when something alerted or scared the skunk, I think it puts them on alert, but they will have one heck of time smelling you with that around.
Fox scent seems to work but both, foxes and deer seem to come right up to the tree and I've even seen the deer smell the tree steps where my buddy climbed the tree. That could be a good thing if it's a nice buck or doe, but if it's a non-target deer they sometimes, mill around trying to figure out if the fox is still in the tree!
Rut or sex scents have been hit or miss for me, mostly miss but, I hunt on public land and,I think the deer have too many negative encounters for it to work well. I have had a little better luck on private land, but it still freaks out the does a lot of times so I, don't use it much.
As for ScentLok, I think it can work, but not like they claim where you can forget the wind and hunt. It's just that you have to spend a lot of time and energy to keep it clean.
I try to be as scent free as possible by washing with scent free soap and washing all my clothes with scent free soap from a month before the season starts till the end. I also play the wind and don't hunt a stand unless I have a favorable wind for that area.
I also have a Scent Crusher bag that I use if I really sweat or want to treat my hunting clothes between washes, but I take the clothes out afterward and hang them so the ozone dissapates. They do notice the ozone smell, and some mature deer will react negatively to it at times.
My goal is to reduce my scent profile as much as possible and be a ghost! That way, if the deer do smell me, hopefully, they will think it's old or residual scent and give me enough time for a shot.
Thanks,
Roger
