Review on Mecurate Digital Electronic Measures Degree by Dwayne Meurer

This is a very good goniometer and level. The display is clear and bright, and you can turn the beep on or off. The display can be switched to different readings such as degrees, inches/feet or cm and has a built in magnet that keeps it in place on magnetic surfaces. The device turns off after about 3 minutes of inactivity to save battery power.
