Poor Man's Chrony?

[Styrak]

I searched for it on here. Couldn't find anything.
So what is a "poor man's" chrony exactly?
How do you do it? It would be interesting to measure the FPS of my guns.

Aluminum cans are what's referred to as poor man's chrony. Some people gauge their gun's FPS based on degree of BB penetration to a particular part of the can at a given distance. However, since cans vary widely country-to-country, beverage-to-beverage, it's not a particularly reliable means to chrony one's gun.

someone also came up with another method, where they used two microphones frm the dollar store, spaced apart and using the time/distance between microphones and when they pick up the sound of the bb going through a piece of paper they were able to calculate approx fps.

side by side, my microphone chrony was only around 20fps the real deal.
