I shouldn't have fallen asleep in math class

Dang, and to think I wouldn't use geometry when I got out of high school!! I should have paid attention. OH well, at least I passed with a 75[]

Thanks Phade, now I'll have to throw a calculator in my pack along with the rest of the stuff I carry!!

I didnt even bother to throw in the height of your target either[:-]

Imagine calculating that out.....

Your math formula is correct if you are building a roof. What they are trieng to tell you is the only distance you need is from the base of your tree to the target. Forget about the extra distance from the angle. The downward projection makes up for that.

I disagree. Heres a quick copy from Bob Humphrey, a writer for Game and Fish Mag. He is a noted archery expert.

ELEVATION
It's probably fair to say most archers hunt from tree stands. I'd venture to guess that a considerable number of them don't practice from elevated stands. That's a big mistake. The trajectory of an arrow fired horizontally is quite different from one fired at a steep downward angle. On a downward shot, the effect of gravity is amplified, usually resulting in an overshot.

What is the original poster doing????? He is dead on target on the ground, but from a stand he is high.... The cause? It's an overshot.

Gravity will affect the arrow the same at any angle it doesn't matter. Trust me I just got a 100 percent on my physics test yesterday and it involved this. The angle of the arrow would affect air resistence but I doubt that would cause anything.

You are actually shooting the distance of the angle not the base of the tree to the deer, so unless the very minimal air resistence is causing you to shoot hight then this is not the problem either.

The main thing is bending at the waist this should solve most of the problem.

After rethinking this, and 20 minutes worth of doodling .....

What Walzer said.

(shutting up now)

Kimber, The affect of time vs. arrow trajectory would make the arrow drop, so this can't be contributing to him shooting high.

Ok, I have a fast bow and mine shoots 8" high out of a treestand at 25 ft high. When zeroed at 20 yards from the treestand, I am good from the base of the tree all the way out to 32 yards with one pin. At 32 yards I am 2" low. When I shoot off the ground, zeroed at 20 yards, I am about 5 to 6" low at 30 yards. This is with very lite arrows.
If elevation and gravity pull doesn't change the shot then explain this. Take a rifle place parallel 3 ft off ground, fired a shot. Now take the same rifle 3 ft off the ground still parallel but shooting up a mountian, fire a shot. The bullet shot uphill will impact the ground at a closer distance than then bullet fired on flat ground. Same with a Bow. This happens all the time when us Florida hunters go out west.

I disagree, He's hitting HIGH from the tree not low. Its a trajectory thing. Angled shots are affected by gravity like the horizontal distance. Thats why you hit high when you shoot something that looks to be twenty yards from your stand. Its because from the base of your tree the target is closer than it s on the shot angle. The farther out you go the less its noticable & this might be becasuse of air resistance slowing the arrow but its just as likely that since its further out the angle off horizontal is much less.
The closer you get to the tree the worse it gets. Shoot straight down sometime, you'll be off a foot or so at 20 feet because now gravity aint doing squatt.

Thats what a pendulum does, no? The further you lean over the higher t swings thereby lowering your point of impact.
