[QUOTE="Pdvdh, post: 438410, member: 4191"] True, if you set them up in series, with the start and stop skyscreens from each chronograph set up one following the other. As in start followed by the stop skyscreen for the first unit. Then start followed by the stop skyscreen for the second unit, etc... The better way to set up multiple chronograph skyscreens is as illustrated in my Thread: [url]http://www.longrangehunting.com/forums/f19/new-oehler-35p-new-skyscreen-rail-first-test-data-60778/[/url] A fellow would want to set up duplicate or triplicate chronographs' skyscreens such that the bullets fly over ALL of the initial 'start' skyscreens firstly, and then over ALL of the second 'stop' skyscreens secondly.
