I always wonder how shooters with inexpensive chronographs know they're accurate.
For my job, they have to be, which is why I've owned an Oehler 35P for many years. All the other chronographs I use are tested directly against the Oehler. The three Shooting Chronys I've owned have not worked out in the long run--though in one instance the problem was a .41 Magnum bullet through the center of the display. But the other two eventually ended up being erratic.
With all the available chronographs, many very affordable, it would be an interesting article comparing them to something known for accuracy such as the Oehler. I remember you mentioning at one time the ProChrono was also fairly accurate compared to the Oehler and after having the Digital for 20+ years it reinforced my confidence in it and I upgraded to the DLX.
