If was given this one absolute of deer hunting when I was much younger, I would have been much more successful in my younger days.... Never ignore the wind - because the deer surely don't. Deer generally move with the wind on their nose, either straight on or a quartering angle. They rarely move any direction with the wind on their back. When I say "wind" I really mean airflow. It may appear to be windless to you, but generally the air is flowing a certain direction (but not always).
Why is this important? Because it's IMPOSSIBLE to mask your human odor and any other odors you or your clothing may have attached to you. A deer's nose it's it's #1 defense, and although their eyes and ears are amazing as well in terms of defense, they don't compare to their nose.
Once a deer has survived a NJ hunting season, they are officially "educated". First year fawns do not yet fully recognize the danger of the human smell, but they learn quick. Most deer herds rely on the super-senses of alpha does. The younger deer generally follow their lead as they travel from bedding/safety toward daily food sources.
While it is great and paramount to seek stand locations that "funnel" or concentrate the most deer movement near you, you need to factor stand location as to what the prevailing wind would be for the time of year you hunt it (if a fixed, lock on stand). This is where a climber could offer you some distinct advantage provided you can find the right tree suitable for a climber with enough cover to break up your background when deer look up at you - you don't want to be "skylined". Do not setup directly upwind of direction deer will be coming from, you want to be in position to be just off the edge of your scentline to where the deer move through... (Much easier said than done - but fooling a deer's nose is the key to success, and the ONLY way to effectively do that is to make sure you never in position where your scent is blowing toward them).
Again you can't make yourself odorless to a deer, but you can do all you can with washing your clothes in baking soda or various scent free detergents, airing them outside as much as you can , and I do believe the various scent-elimination sprays have their purpose in terms of removing odors from your clothing and boots (I always spray boots well before walking in - eliminating your trail goes a long way as well, especially if you expect deer to cross your trail). If you can set up in such a way where deer won't have to cross your trail you walked in on - even better but all depends on your setup.
If you can just master this aspect of deer hunting within 5 years time, you will rapidly accelerate your success, as again - avoiding a deer's nose is the absolute toughest part of deer hunting, regardless of weapon or season. I know for a fact deer can smell you from at least 1/2 a mile, possibly even more.
