I'm not in any club and I can shot when I can- which is not very much.
I am doing this for my science fair project, and I am soooo confused! what in the world is 'sight mark setting' and 'eye to sight pin'??????
This program was meant mostly as an easy way to estimate your arrow speed.
However if you give the program first your 20m/30m sight marks and then your 70m/90m, you can find out how much speed your arrow loses at longer distances. If you fire two shots using the same pin at different distances and measure the arrow drop, you should be able to determine the speed without knowing distance to the eye, non? Dan 21/10/08 : Good calculator however it does not seem to account for decceleration and would only be the average arrow speed from distance one to distance 2, beyond distance 2 your arrow would be constantly deccelerating and thus your extrapolated sight pin settings are slightly off.
The only thing you need to know is the distance from your eye to the sight pin. I am trying to make a ballistic module for bowhunters, like yours but take also Ballistic Coefficient, but I cannot find out how to calculate speed at differents distance. I used Mathematica to find the solution and it's a formula 4 lines long.
This is usually something around draw length sight extension but it's best if you measure it accurately. have to measure the distance from eye to scope to make sure it is accurate. Could you place a link to the formula you have used. Someday I will describe how it is done in a separate page.

This program can calculate your arrow speed, given two previously known sight marks.
I am only trying to find an easy way to find out how fast the arrow went... I'm not in any club and I can shot when I can- which is not very much.

SURFELITE 10/02/10 : i am also doing a science fare project for my freshman class. can someone post something/someway to help me fine a way to figure out the acceleration,velocity, and speed of a normal pull back tension of the bow a 45lbs.
I'd like to translate it in french in order to use it on my club website (it would display your translated page inside a frame).
