I was using a Pro-Chrono but, since I shoot at a public range, I purchased the Magnetospeed V3 chrono. I won't be going back to the Pro-Chrono. When I first got it, I tried the different spacers on 2 of my rifles for which I was reloading, so that I would not waste time at the range doing this. After that, it was easy to install on each barrel. Another advantage of this chrono is that it did not miss recording a single shot, unlike my Pro-Chrono. I recommend the V3 version highly.
