Things I liked: After reading about all the possible problems with light and the ProChrono I was nervous about buying it. But! No problems at all. Have used it on cloudy and sunny days, in tree shade and full sunlight and no light issues at all. When combined with Chair Gun Pro, it's a great way to figure out your maximum scope zeroing distance. My air gun is an FX Royale 500 25. I'm a newbie in paradise!

What others should know: The bluetooth option isn't really necessary unless you are putting this down range. Using it's a piece of cake. I suspect it's the guys who put chronys down range that end up shooting them.

Things I liked: It is simple to setup and it just works every time. I used it to log about 150 shots and have only gotten 2 errors and that was my fault for not shooting exactly over the sensors.

Things I would have changed: Nothing.

What others should know: I would recommend this chrony to anyone with an airgun.

Things I liked: The easiness of using. Every time I target shoot,, which may be 4 times a week, I set up and shoot across it. It is not practical to use when hunting or backyard pest elimination, strictly for ballistic comparison. It works as advertised.

Things I would have changed: I don't know other than its light weight could be an issue on very breezy/windy days, which I don't shoot on those days anyway, with or without the chrono.

What others should know: Not an immediate absolute must probably for everyone, but you will be glad when you get it. I have five air rifles, four .177 and one .22 caliber, and it allows you to compare them. It is always good to know the muzzle velocities of all the different pellets and air rifles that you have. Could enhance your choice of which to use.

  • 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.

  • Don from USA asked:

    Are the "Light diffusers" included as standard equipment?
