I bought this digital protractor to use as a spirit level or goniometer. I have vision problems, so an easy-to-read display was important to me. The display did not disappoint. This angle finder is very easy to use and appears to be accurate. My only suggestion would be to add some sort of audio gauge if you were at zero.
