Chrono tests

[Robert Pougnier]

Put two different arrows through the chronograph today, with two different bows. Just out of curiosity and for education's sake.

one arrow is 575gn, the other 300gn.

One bow pulls 50#, the other pulls 43#. Both drawn to 28 inches.

Here are the results

50# pyramid reflex shot a 575gn arrow at 140fps. Chatgpt (i know lol) estimates for a 10gpp arrow this would be between 148-153 fps. Not bad.

With the same bow, the 300gn arrow was shot 158 fps. I can't promise my release is consistent, but I was trying for consistency in release and draw length.

Next set of photos is a 43# rock maple bow with reflexed tips. It shot the 575 gn arrow at 127 fps. Again chatgpt estimates about the same, 150fps with a 10 gpp arrow. Not bad either.

Rock maple bow with 575gn arrow.

I unfortunately don't have, at the moment, any exact 10 gpp arrows for any of my bows.

How are you liking that chrono? Im about ready to toss mine into the ocean. Those numbers are lethal for deer. Id not want to catch one. Have you been trying to increase your speed?

I actually really don't like it! I've had it for years and just started playing with it. Most of the time it does not register anything, and often gives an error code. I don't know if I can trust it at all. And I tend to shoot heavier shafts anyways so it never plays in my favor. I'd love to shoot for distance instead but I'm down in SC for a few months and don't have access to large spaces (or my shop for that matter).

It's fun to push designs and efficiency so in a sense I am trying to make faster bows, but I have no intention of making any long shots at anything that moves. So it's not the most relevant thing to me.

Are you thinking about getting a different one of just ditching altogether?
