Make sure Your staying as Scent-free as possible,try slipping in as quiet as possible with limited movement.If You over Hunt an Area the Deer are avoiding You and they know Your there....put up a few different stands and hunt the one that has the correct wind direction that won't give You away?
I Bow Hunted for about 4 years before I finally got it right and had Deer under me within Bow Range and after lots of practice shooting my Bow.Stay after the Deer and learn each time You go out.At least Your not taking chances at taking bad shots....that makes You a Respectable Hunter!
