RE: How can I increase chances of getting a buck
Pattern a buck. Look for a rubline, then walk it backwards (with the rubs behind you) until you get intoits daytimecore area (which is often in thick cover, possibly on the downwind side of a hill), where you should find several rubs on smallsaplings and several large beds. There may be large clumps of deer scat in thearea too.
Then set up near the core area.
