I like my Competition Electronics Pro Chrono Digital just fine...it cost about $100, has always been accurate and reliable, easy to read from 10-20 feet, stores plenty of data, etc.
Its actually my 3rd one...I shot the first 2
...it happens. (1 was at 800 yards, the other was at 1,000 yards...the cost of accurate BC measurements, LOL)
Then I got smart(er)...when shooting over it from a distance, I place an 18" wide section of railroad rail in front of it...no more damage chrono's.
