Chrony F-1 Review

http://www.doskosport.com/ Try F-1 Chrony; this is a chrony which will measure the speed of your bullets, arrows, etc from 30 to 7000 fps and with better than 0.5 accuracy. This chrony is very easy to use just unfold it, mount on a tripod or place on a table, insert diffusers and shoot in less than 2 minutes. F-1 Chrony is tough and reliable because it is made of 20 gauge steel but weighs less than 2.5 lbs so that you can conveniently carry it wherever you want; this chrony’s measurement is 7.50 x 4.50 x 2.75 when folded. The velocity stays on display until you shoot again and gives numbered shot velocities.
