Nice inexpensive chronograph. - PACT Model 1 XP Chronograph System

I’ve had mine 40+ years and no problems. As long as it’s not cloudy out I’ve never had it miss a shot.
I use it with a contractor’s tripod so the screens stay put. Had lots of people at the gun club borrow it and no has had any issues whatsoever with it. If you’re capable of opening a can of sardines, you’ll get along great with it.
