I use a cheapo Caldwell chrony but it more than does the job for my purposes. It is invaluable when working up a new load and great to ensure I am maintaining consistency over my favorite loads. When I first started out I had to make use of a community property chrony at my range so I never did load and shoot anything without quantifiable information. It's just so much easier now setting up on my property for testing.

I'm not a precision/long distance shooter. I'm only concerned with the most common pistol calibers and .300 Blackout so I'm very pleased with the results and minimal investment I have in my Caldwell system.
