As long as you are playing on a course with 7' tall flags, you will be fine. Just concentrate on light breathing when using it. However, once you go to an 8' flag course, all bets are off. I can't make it anywhere near accurate at 8' courses. The manual gives you some ridiculous formula to use.
Small, simple and a good basic golf tool to have on the course for when you need a quick gauge of distance and nothing else is available to utilize for gauging distance.
