Borrowing a chronograph?

If anyone in the Tucson area happens to have a chronograph lying around, would it be possible for me to borrow it for a range session or two? I want to get some data for my reloads, but I lack a chrony.
It doesn’t need to be fancy, and I’d be willing to provide some sort of reasonable collateral against my accidentally shooting it.
If so, please contact me by email. Thanks!
