never seen one, but perfect for the junior high math teacher to show applied sciences. it would enhance future survey interests

I have never seen such a thing but it might be fun to play with, to see how close one could close with one on a dare. Have seen some amazing closures by compass.

All we ever used in trig class were those big wooden protractors and a string or chalk line.
The best teaching aid is something simple and easily read.
