shooting distance

Post by gogo » Thu Sep 24, 2009 8:38 am

Lost my math skills. If your 10ft up in your treestand and your target is 60 ft away how far is it away from you. Is there a rule of thumb to figure that out, it is for us with no range finder.

I am not a math wizard but I have used this formula many times...


Frank 25 has it just about right....the formula for that is...

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...

(A) squared plus (B) squared equals (C) squared....(A) being the height of your treestand...(B) being the distance to the target. from the base of the tree...and (C) being the diagonal distance to the target....thus 10 squared equals 100...60 squared equals 3600...add them and you get 3700...take the square root of 3700 and you get 60.82 or rounded off 61 feet...pretty close to 20 yards...this formula is also useful to determine a square corner for building decks and patios...its called the 3, 4 and 5 rule....measure 3 feet on one edge...then 4 feet on the other side....place your tape measure exactly 5 feet between the two points and you have a right angle... because 3 squared equale 9... plus 4 squared equals 16...added equals 25....the square root of 25 equals 5...If I remember correctly this is called Pythagoreans Theorem....the one and only thing I remember from 8thgrade math....I have used it quite a bit to build decks...

I was really hoping Y=MX+B could solve this. :lol:

So let's see if I got this straight, if I'm bow hunting from a stand the deer seem father away so I range them. If I'm in a stand they're effectively farther away because of the evil forces of gravity and the math. But because the deer are going to duck the string I have to shoot low. Sheesh. Like a wise archer once said: Just aim normally and put an arrow in there. The problem for us is really only magnified at shorter ranges where if you are off by even 10 yds in your ranging you're only talking a couple of inches anyways.

The best advice is practice from a stand at varying ranges. This is why I made a stand for my Black Hole block so that I can adjust it for varying angles.

The answer is

Simple answer - on relatively level ground, not enough to worry about. :wink: :lol:

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.

X 2.

10ft up really isn't an issue for a 300fps arrow. Its almost the same as being on the ground.

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.

Ok folks the drift I got is forget pi this and pi that, not much difference in distance just fire away as normal. thanks for all the replies

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...
