I read a thread about a month ago on OGF and the guy claimed his procure scent applying to his cranks was out catching his other cranks 4 to 1.Said using trophy walleye scent.I had never heard of scent at the time either.The one tip they gave was you had to wash the scent off your lure after using or would stink up your tackle box.I have on the list to buy.Wouldn't put on your harnesses with worms but could put on spoons.
