[QUOTE="Blaine Fields, post: 22666, member: 183"] I suppose that a Chrony is better than nothing, but not by much. The problem is that because the Chrony folds open, the user really doesn't have a way to ensure that it is opened to exactly the same degree every time or that it is completely flat when it is opened for business. The result is that there is no way to ensure that the distance from the first photosensor to the second is identical from one use to another or that the distance is that assumed by the internal software that computes bullet speed. Generally, it's going to be shorter and hence will show higher velocities than actual. Recently I bought the Oehler 35P and am very pleased. The first thing I found out was that my Chrony was misreading my handloads by 100 fps or so. So, my advice is to buy the 35P - it's accurate from day one and you'll like the convenience of the printer with its ability to compute common statistical data. [/QUOTE]
