I don't understand why I didn't buy this indicator earlier. It is the only instrument that is accurate enough and extremely stable for my needs in the steel industry. I've taken measurements for my desk and tool box multiple times and returned the same readings each time. The ring rotates very easily and hand movement is fairly smooth and responsive. I was concerned that the pointer movement would be hourly based on some reviews, but for me that's not the case at all. There is a screw securing the ring that needs to be unscrewed, it is very obvious for its purpose and is included in the kit. cozy. Anyhow, this thing works great every time and is a joy to use. Money well spent!
