Review on Digital Protractor Goniometer Professional Accuracy by Matt Larsen

The device is very good and solidly made from good materials and does not require any filigree handling of the device. convenience of work. Turn on the display and measure the angle. The copied angle appears on the display. We're building a castle and there's a corner. The problem is that when we go through a 180 degree angle, we have to move the clamp screw. Loosen and tighten the screw several times, not sure how long it will last.
