We have a Shooters Chrony in the shop, the blue (Beta?) unit with the separate display. It is really a pain in the ass to use. Sat there for over a year after using it 3 times. I saw a Caldwell go onsale at Midway for $69. Said hell with it and ordered it. Tested it out with my German air rifle. It is known to shoot 850fps with FTS pellets. I tuned it years ago and it is still dead on...has an extreme spread of 7 fps! This has been verified with 3 different chronographs over the last 5 years. So I tested the Caldwell in my house with this gun and it was dead on! Now, this is the best part...you download an app from the Google Store to your phone (IOS or Android) and then you plug in your smartphone and DAMN! Everything on one screen! And you can save all your data and download it to your computer later! You can plug in the BC of the bullet, bullet weight, Temp, Barometric pressure, distance to chrono, notes and descriptions.
