[quote="Missouri_Hunter"]
In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle)...or written as a formula...

There once was an Indian campground w/ many tribes. The son of a squaw in the Hippopotamus tribe got in a fight w/ two other sons and whipped there butt[s].

Moral of the story: The son [sum] of the squaw [square]of the Hippotomous [hypotenuse] is equal to the sons of the squaws of the other two hides.

You can also double and re-double the numbers and the old 3-4-5 triangle works.

6-8-10.....yields...36+64=100

...and can double again, and again for those large decks.

The angle of trajectory is different than a straight measurement. There are multiple factors involved. The best way to determine what your bow will shoot, is to shoot it and skip all the figures. Climb up on your roof and fire away at the different ranges. Then you will have the best figure available.

Someone posted a website last year that had a series of scenarios of deer at different angles and you had to click on the right spot on the deer for the kill shot. Some of those were from above. It was pretty good. I'll try looking for it...

Archery hunting is a sport of inches.
I like that sentence!
I don't practice from an elevated position because I don't hunt from an elevated position. I did pick up a climber to try this year, but I will be sure to practice shooting first so I can understand this gravity issue, for some reason I can't get a grasp on it by just reading.
The other option, unfortunately an expensive option, is a angle compensating range finder.

Just like practicing on flat ground, go climb your stand and shoot at different distances til your satified with your shooting, you won't know where your hitting til you do this, don't wait til the last minute.

Here is a graph that I put together showing what happens as you increase your stand height.

Here is the table version of the graph above for a 15ft height.

bill morrison wrote:gravity only works on objects in the horizontal plane, so the distance for an aiming reference is the distance from the base of your stand to the target assuming that your stand is not on the side of a steep hill and the deer etc. is not significantly below that level. so if target is 15 yard from base of stand that is the pin or crosshair reference that is used for the shot, regardless of height of platform.
How do you turn off the gravity when shooting other than horizontal?

you can't turn off gravity, it only works on an object in the horizontal plane ,so if you look at the graph in earlier reply it is side b that is the distance over which gravity works. same as if you placed a rifle perfectly level and placed a bullet beside the barrel and released it in a free fall the instant the gun was fired both bullets would hit the ground at the same time. as far as the issue of straight down or straight up the gravity is working straight down so you would have to use the pin closest to the line of sight of the arrow, or the lowest pin which would equate to the pin for the farthest horzontal distance.
