Good on a tight budget - Shooting Chrony F-1 9 Volt Chronograph

Used it once so far and ran a gauntlet of calibers through from 22lr sub sonic all the way up to 45 long colt, 243win. 338win. mag. with only 2 error codes. It didn't however register the 17hmr maybe the bullet is too fast for its small size. Super easy to use, dont really need a printer a pen and paper work damn well and easily fit in the box with the chrony, and i have a calculator if i need to check extreme spread or average velocity
Pros: inexspensive
Cons: wouldnt register my 17hmr
