Alternative to a Chrony

Best not use one I fletched

I just tried the sound Method of measuring FPS... worked great. Look up a video on YouTube and you’ll see it’s very accurate. People who have crony already tried the sound method and got nearly the same FPS, just 1 FPS different.

Primitive chrono - shot arrow, hit game before it jumped out of way - plenty fast arrow!    . Couldn't resist!  Good info in this thread!  Still have to learn how to use my chronograph!

How do the audio measurements work?

most audio would normally be with a microphone, but I have been collecting old guitar pickups and stuff to experiment with


would something like this work? one on the target face, on on the bow?

I have always considered using a radar gun. I have one from my baseball-playing days.

There would need to be 2 considerations...well, 3, actually. The 1st would be just simply acquiring one...because at around $79.99 or so which was what my radar gun cost at the time they are not all that less expensive than a chronograph. 2, one would need a second person to actually attempt to gun the arrow’s flight (and they would need to be well-versed enough with using a radar gun to capture an accurate reading). And 3rd, the recorded results would then need to be converted from miles per hour to feet per second.

All in all, I would think that there are other fairly accurate alternatives to a chronograph...and they all might actually provide reasonably accurate results. And from what I have seen with a lot of people’s chronograph speed declarations, FPS numbers gathered by other means would be scrutinized equally as much as those from a supposed chronograph!!
