I had reviewed this product earlier, it disappeared - Caldwell Ballistic Precision Chronograph G2

First of all, if you decide to get this chrono, buy a new tripod to use with it. The one that comes with it is too light and cheap to use on an outdoor range. If the wind blows just a little bit, your chrono will tip over. Secondly, if you use this chrono indoors you must use the led lights to get any readings, but battery life will only last less than an hour, so you better have an external battery pack to keep your chrono working. Third, the G2 will randomly disconnect from bluetooth every few shots. I have had this happen in an indoor range with no one else around and on private property where no one can say there is electronic interference to cause this problem. The last problem occurred today and was the last straw for this piece of garbage. I went out in cold weather, for Texas, to get MVs for 40 degree weather and set up the G2 in the exact same way and exact location as I have before, the only difference is the 40-50 degree temperature change. I started with 308, NO READING and no error message. I doubled checked the level, the assembly, and ensured that the unit was clean. I shot again and No READING. Switched to 6.5CM exact same. Finally I switched to 338LM and I got a reading... 257fps! I fired several more rounds with velocities from 250fps to 1213fps. During all of this, the Bluetooth disconnected 6 times. I bought this product in March and have never once had a flaw free session with it. On a good day, it only registered 4 out of every 5 shots.
