Realtree's Josh Honeycutt has a great tip for keeping big bucks from spooking because they smell you. What is the most common scent give away? Take a look...
Baking soda is a great way to reduce the amount of human scent coming from your mouth. Remember though that toothpaste typically has a minty scent and is not a natural scent in most locations. The baking soda as described in the video has a neutral scent and will help tremendously in eliminating any human scent that deer can pick up on as you move to and from your stand and any downwind scent while you are hunting.
Great tip from Realtree Outdoors!
