One season of guiding I tried to see if scents worked I use 3 different brands with 6 hunters a day 3 did not use any. Pre rut, no different in deer seen. The rut, the hunters not using sent saw more deer but one hunter did report a buck stop and smell the sent first time reported. Post rut sent hunters saw more deer. I know I have never had any luck with them. If you really want to kill big buck save your money go on FML and never stop hunting.
