Dont have a crono.

I found this web site who has at the moment the Chrony Chronograph's on sale.

We picked up the F1 model for $68 delivered and it only took 4 days to get it.

For that sort of money everyone should be able to afford one.

It runs off a 9 volt battery which they supplied all we had to do was go to Wally World and get a camera tripod to mount it on.
