I think most of this has already been said, and I'll chime in.
A climbing tree stand for archery is a must in my book. Can't imagine trying to kill a deer in the woods sneaking up on him.
Ditch the Scent Killer $pray $tuff. A deer's nose is very sensitive. A few sprays of that stuff ain't gonna stop us, well, we still stink like humans.
Don't get caught up in the latest and greatest equipment. The "latest and greatest" seems to be worse on archery equipment. My bow is circa 2000, and my ML is an old Knight from the mid 1990's. When I us a crossbow, well, it is a hand-me-down from about 15 years ago.
Squirrel hunting is a good way to get in the woods, and sit still. If you see a deer, note where it came from, where it is going. If you see the same general movement movement, hmmm.
Check that trail camera year-round. Not every week during the off-season, but every few weeks.
And if 30-06Guy offered, take him up on it! He's always killing deer! There comes a time in a hunter's development that it is more exciting to get a new hunter (child, friend, etc.) an opportunity at a deer, turkey, or whatever it is you're hunting. So it's likely he is there too!
If you're stuck on archery, awesome. If you're open to expanding, get a good muzzleloader. What does good mean? Stainless/nitride/or some other weather resistant coating. Uses 209 shotgun primers. And a scope that has a lot of eye relief (I shoot a Simmons fixed 4X shotgun scope.) A ML opens up your range significantly.
Longer than I expected, but good luck, and post some pics!
