1) Find a food source and you will find deer; acorns, persimmons, etc. They will visit these areas often but they also browse as they move about. Look for trails where they cross roads/ditches, along creek or river bottoms. Check with your local game warden, land management maps, and certainly other hunters that will be willing to get you started.
2) Here the prevailing wind is from the west so downwind would be on the east side of a line drawn south to north. Let's say the local weather station tells you there is a northern wind. They always tell you from which direction the wind is coming. Therefore, where the wind is going is downwind.
3) A deer doesn't care how much money you spend of your equipment and will be just as dead if shot with a $200 bow as if shot with a $900 bow. I have shot compounds for many years but now use a custom recurve. That is a pp (personal preference). You don't need a lot of bells and whistles on your bow but it certainly would look impressive to other archers. Imo, for hunting, the less the better. A standard sight with at most 2 or 3 pins will be fine (the more pins the greater your chance of using the wrong pin during the excitement). A good quiver that is easily detached, secure, and completely covers the broadheads is a must. If necessary, use silencers should the bow be noisy. The list can go on - such as arm guard, finger tab or release, etc. Practice with the equipment you will be using in the field; this includes clothing.
4) Take a good compass (not GPS). Sometimes you will shoot a deer and the blood trail will be very scant if not impossible to see. Take a reading at the last place you saw the deer or heard the deer. If you can't find a good blood trail go back to the stand and use the compass to take you to the last sighting or noise. Sometimes this will take you right to it or a sign that you can follow. Small pruning shears to clear a branch out of the way. Paper tissue to use when tracking the deer. Good flashlight with extra batteries. Certainly safety equipment. As before, the list can go on and on. BTW, seldom will you knock the deer down in it's track unless a spine shot so be prepared to learn how to track the deer.
