Are you using a tree stand? Ground Blind? Spot and stalk? Still hunting?
One thing to know about whitetails is that they are very curious and if you jump up some deer and they run away, just sit where you are, and better yet get yourself ready to take a shot because often times they will circle back around if you didn't scare the bejeezus out of them.
If you already have some patterned, then I would consider a ground blind. Whitetails will often use the same paths for weeks until they change things up a bit.
Also, you tube videos about "string jump". I have had a whitetail actually duck my arrow.
