I will keep gettin on this site to see if anyone has answered my question thank you.SURFELITE 10/02/10 : *also the arro need to either be a carbon/graphite or aluminum arrow thank you yet again f 05/03/10 : fffff Hans-Erich Dunker - Germany 08/06/10 : Its a nice helpful tool and incredible accurate - thanks Deano 06/08/10 : I checked the results given by your program, aginst archers advantage.If you're interested, contact me : bestel (at) ifrance (dot) com john r 26/07/07 : i used your speed chart and checked it against many of the known sight marks that i have and it was accurate for all of them.im not the greatest archer but found your formula works for me. Apostolos 03/10/07 : Archimedes: you'd better use one of the other calculator that work on principle of draw weight and arrow weight.If I find some time, I will update the calculator with your suggestions. Joan Smith 05/06/09 : I was asked how fast an arrow travels so I Googled to find out.I found this and thought the very thing I'l just print this out for future questions! Robin Of Locksley 19/06/09 : This calculator is quite vague (even for English standards).I am very happy to live with this minor issue, but if you ever found yourself with nothing to do sometime ........!!! Best wishes, David Morrish Harry Marx 03/09/08 : I did the same thing, but derived formula myself. Normally the arrow is shot at 42 to 47 degrees with specialist bows?I have studied balistics but have no luck with the maths. helped me with science fair Apostolis 13/01/09 : Thank you all for your comments. I am shooting field ranges where uphill/downhill calculations depend on arrow speed. Sam S44 22/03/09 : Can you give us Yards and inches?
Or its just enought to know the sight difrence between two distance?
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'??????
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.
This would be the most accurate way to determine the speed for the particular setup you're using. Patrick Andresz 17/07/09 : Thank you very much for this nice programm ! Don Walker 22/09/09 : an excellent tool but for one thing! would it be possible to produce a version in Yards and diference in site marks settings in mm for old field archers Mark 25/09/09 : I didn't believe it when I looked at the numbers, as the difference between each 5M distance for time and sight markings seemed to be almost constant.
It's very helpfull and so helped me to verifie my estimation of the speed of my arrows. But then thinking about the speed of most compounds (300 fps) this would make sense.
I'm not a ballistic engineer, but very curious about how you find the formula. Just to test the calculator I entered a 10cm difference between to distances - then you can see how the decceleration, gravitational and other forces start to show a non-linear relationship. Mark 25/09/09 : Robin or Locksley : The things you mention are constants for the two shots from you bow setup and your arrows. Decceleration, gravitational forces and other forces are taken into account by the formular - see my earlier comment.
