I have a Shooting Chrony with the remote readout. It is very sensitive to low side light as I suspect most all chronographs are. I tried paper targets over the top and side, but noting worked really good. One day I discovered that since I mount it on a camera tripod I have all kinds of adjustment in different planes. So I just tilted the chrony over until the sun was as if directly overhead. Worked just fine then. I don't have the print out but if you will get an old plug in off some charger or whaterver, after you run a string of shots you can just push the plugin and out quickly and it will give you all the readings that go to a print out. You just have to do it one at a time. It gives number of shots, high, low, average and vel. of each shot. Also Es and sD.
