Well first of all, he didnt get that big by being dumb and hes only going to get smarter with age. Mature deer will normally come in head into the wind. Also again, Id avoid that stand for a couple days at least and hunt an alternate stand. I woudl also pay more attention to the wind, your scent, entry and exit routes, movement, make sure youre stand is facing due north. This way the sun is never in your eyes, or reflecting off any equipment that you have. Try some good cover scent around the base of your stand. The scent wafers work well and last forever as long as you put them back in the canister after every hunt. Use something that is found in your area, If you hunt in an area that has pine trees you dont want to bring an apple scent or acorn scent. Theyll know something is up. Use pine scent for pine areas, apple where apples are found in the area, acorns if your hunting an oak stand. Common sense. Once the rut starts use doe the does estrus wafers.
