I can't speak of the high dollar chronys, but I have a Shooting Chrony F1 which is about $100 [mine was free, even better]. Nothing fancy at all about it, will only show the speed of each shot. No memory, printer, nothing. But I know how to use a pen and paper. I only use it when working up a load and I just write each load down on paper, then jot down the speed after each shot, I can figure the rest out later. I see no sense in spening a few hundred dollars for what I can do on paper for free.
