I have a Caldwell G2 and a LabRadar. LabRadar is newer but I still like the G2. I found it’s always nice to have two tools that do the same thing so I’m not dead in the water if one goes out. Even though I have two, I only chrono about half the time. I did do it every time for a little while but I found it sucks the fun out of shooting and feels like brain damage when using every time.
