I use the HS earth scent wafers and put them as markers from my stand. I don't think it brings deer in thats my job to set up where the deer will come in not some manufacturer. I put them out in all 4 directions on deer trails if possiable I know thats 20 yards now and it takes the deers attention to them and gives me a little extra edge when drawing my bow. I have shot 2 deer batting these scent wafers around with there nose.
