no problems and good value for the price.

### ⭐⭐⭐⭐⭐ Map protractor
*by M***M on 3 March 2026*

Great protractor for land navigation using maps. Punched a hole in the middle with a hot needle and threaded a string through it for measuring angles across a map. I bought it for the large numbers since so many others have very small numbers. Plus it was dirt cheap. Very convenient size. Very sturdy and will likely last a long time.
