The addition of a fairly new technology, radar, has shaken up the world of chronographs. But what of the older, optical models? They still work. I have owned at least 4 different optical models, starting with the old fold-in-half-when-done Shooting Chrony back in the big-shoulder-pad era of the 1980s. I had to have two of them since I shot the first one. I then bought Caldwell’s Ballistic Precision and Pro models. I even managed to shoot one of those.
