Dunno if this will work for the size of our BB's, but for the price, it might be worth a try. Might be a cheaper alternative to a chrono. I might pick one up just to test. I wanna use it to check my speed when longboarding! :D

I'll take a guess the pop can method would be as accurate.

But, do let's know how well it works (or doesn't)!

nice find!

It's showing up on a police radar countermeasures forum:

On the last page, someone reports working results to 50' clocking cars. Looks like the device has poor frequency consistency so it doesn't reliably trigger high end radar detectors.

I gotta buy one for my box of measuring tools now.

If anyone can find one here in Canada, let me know cuz I can't find it anywhere online up here :) I'd check Walmart, but it's pretty far from where I live. Maybe The Bay will have it.

Did you try Ebay?

better off with the microphone chrony posted earlier in general.

better off with the real chrony hehe.
It's cheaper than people think.
