Try this trick if your hunting the acorns or soft mast food sources. Deer tend to go to the freshest fallen acorns and soft mast such as crab apples, persimmons etc.
Take a some acorns up in the tree with you and periodically drop some out every five minutes or so. Deer listen for this sound when searching for fresh food.
Ive killed alot of deer using this technique. Last year I was hunting some crabapple trees when a doe and a button buck started feeding by me at about 50 yards. I dropped a crabapple and both deer stopped and looked my direction. I dropped another one and they both made a b- line for my tree. They milled around for a few minutes looking and smelling when I decided to take the doe.
Perfect 15 yard shot.
I do use those rubber latex surgical type gloves when I handle the fruit so I dont leave any scent. I have even pulled deer out of their beds in the middle of the day doing this.
