I only hunt the wind no scent control at all. Not that there is anything wrong with it nor do I have a problem with anyone that uses it. It just I choose not to waste my money on it. What ever happens happens. Maybe one day I will take the plunge and buy a suit and cover scents but at this point I see it as a waste because deer can smell alot more than one scent at a time and distinguish between the two or more scents they smell. I read an article that stated the number of scent pallets that a deer had and it was alot more than any dog they had listed.
