Things I liked: Easy to set up and use. It seems accurate enough. The direction were well done and easy to follow. Only regret is that I did not order the indoor lighting system when I ordered the Chronograph. I had to go back and purchase it later.

Things I would have changed: Maybe a little larger Digital Readout.Window.

What others should know: If your at all curious about what your gun is doing with different gr. pellets you need one of these.

  • Tim from USA asked:

    Can I get a outlet adapter to supply electricity instead of using a battery? This thing drains batteries even when its turned off.

    • Mark from USA:

      Yes There is power converter available.

  • rfguy from USA asked:

    Does this allow for a 9 volt battery eliminator (Wall Wart)?

    • Gerald from USA asked:

      Is there any chance the ProChrono Digital Chronograph will work with a Mac (using Excel) as well as a PC?

      • richard from USA:

        search 'chrono bluetooth and you'll find it!

      • richard from USA:

        it appears with the bluetooth option it can at least work with iPads etc. Maybe that translates to desktops? I'm gonna find out! I suspect it will.
