I have seen several chronographs shot, so I don't think I am above doing that. But I couldn't see myself using all the many features offered on the higher end chronos. I am interested in simply seeing the velocity of my loads. I don't really care about standard deviation, extreme spread, printers etc. I am a lot more interested in the accuracy of the load on paper. So, I bought the bottom of the line Chrony. I paid $44 for it, so if an accident happens, it won't be a huge loss. One of my priorities in buying a chronograph was to get one that was as simple as possible. I didn't want something that was such a pain to load in the car and set up that I wouldn't want to use it. The little Chrony works for me. I just leave it in the back seat of my pickup along with most of my shooting gear (I shoot almost every day). You simply unfold it, turn on the switch, and shoot. Most of the time I don't even put the sun shades on it. If I was going to buy a more feature intensive unit, I would get the one that allows you to measure pressure in addition to everything else.
