Here are a couple images to serve as a refresher on where to place you arrow / bullet.
Having a rangefinder that you can set to compute the calculations for you makes it very easy.
The illustration below is of a Leupold Range finder that has the True Ballistic Range feature. There are a number of manufacturers that offer this feature.
The rangefinder in the illustration below is set for older bows with draw weights below 50 pounds. The deer is 40 yards away (Line of Sight), at a 40 degree angle from the archer. The range finder has calculated that effective range is 34 yards.
So what did we do before all these fancy rangefinders? What I did was the old fashioned, pick my tree stand location and pace off a two or three trees as distance guides, climb up the desired height and estimated where my sight pin would need to be based upon previous experience. For longer distance rifle shots, we would estimate ranges based upon experience and take the shot. In other words practice and experience is key. Spending time on the archery and rifle range is also key. Technology may not always be there for you.
Scent control in Florida is an oxymoron: "A combination of words that have opposite or very different meanings" - Merriam-Webster dictionary.
Ok, having made that pronouncement, and knowing we may have joined a serious debate. We will now go even go further, if you buy scent control sprays, etc., you are probably throwing your money away.
........Yes, we said it.......and now that the scent control industry is busy preparing concrete hunting boots for us, we would like to offer some additional information
We enter the following article into evidence:
Furthermore, it's my personal experience that often it's so f-ing hot during bow season that there is nothing known to mankind that can effectively mask your scent.
While the debate and marketing campaigns rage on, we will offer a few honest tips and techniques that have worked for us. Most of these are unrelated to the scent discussion but work.
1. Getting to you stand location: Yes, get there in the dark. It's better to sit in your tree stand of an hour or so in the dark then get all the game upset during daylight hours.
2. If you can stay off the game trials, do it. If you can walk through water, do it. If you can avoid touching trees and brush, do it.
3. When you climb the tree you're going to hunt from, climb at least 20 feet up. Higher is better.
4. When you get settled, check the wind direction and for thermals.
5. Deer scent and calls can work. Deer are curious.
So have our lessons been proven effective?
We have killed many deer and hogs that have walked close to or under our stands even when we wet with sweat. Why, because were high enough that our scent did not translate to ground level.
One final tip: When you are are hunting at high tree stand elevations,adjust your bow shots according to the trajectory of your arrow. Many range finders will do this automatically but don't take it for granted. If your high in tree, 35 yards from your target but only 25 yards line of sight, you should probably use your 25 yard pin!
