Can't remember when I bought it but I have an old working chronogrph. I have been working up a load using 147gr Berry plated in a G34. I test loads in my garage. Got acreage, but the neighbors get nervous. Anyway, good bullet stop, about 30 feet to target and 25 feet to chrono. During the day when I step into the garage and fire 3-5 rounds I was getting random readings. Screens installed,lights on, and a good battery.
Last night (dark) I went to the garage, turned just the chrono lights on and fired a handful. Got readings as I would expect. Vaariation of no more than 8-10 fps.
I haven't used the chrono for a long time. Seems as I remember, you got better readings outside on an overcast day. Bright sunlight caused problems. Need some expertise on the subject. It is a Chrony Delta Model
