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.
The view is quite clear and bright. Comfortable in your hand and compact enough to store easily. Usefulness is the main reason for the tool, that's where it fails. The magnification make it nearly impossible to stay still enough to read the yardage.
