Sure will.
You get a momentary contact switch, I got a real small one from radio shack, it fits in the end of an old marker body with a little hot glue.
Get an old set of stero headphones and cut off the head set you just need the jack and the wires.
Strip the wires back and when you have a few shots on the crony touch a pair of wires together and when you get the righ two wires the display will start reading the lo, high, extrem spread, average deviation, and then each shot fps.
Don't worry you can't hurt it with the wrong wires but when you get the right pair hook them to the switch and glue it in a holder of some sort.
Here's mine with the switch shown.
