We have tried various shot timers with moderate success, however in time the electronics stopped working. Upon the advice of our local USPSA leaders, we tried out a CED 7000, and loved it! We bought 2 more, and would like to share our CED 7000 Shot Timer Review .
The CED 7000 has functioned well for us, and is fairly simple to use. It is not too complicated, yet has all the needed features.
Our only complaint about the CED 7000 came from a client that purchased one upon our recommendation. He noticed that at his indoor range, it was picking up the shots of someone 3 lanes away. He decided to adjust sensitivity of the CED 7000 according to THESE guidelines. Despite adjusting to the minimum, the timer still picked up unwanted noise.
Our team of world class shooting instructors loves using this timer, and we think you will as well! You may buy one through our Amazon affiliate link here: https://amzn.to/2uaeYJl
