iGaging Digital Angle Protractor

After adding a compact extension ladder to an attic opening I needed to add a plywood door and molding. The opening was square at only one corner. I used this great little tool to measure the other three angles of this "trapezoid" and created a very nice looking trimmed-out hatchway.

I picked this unit up almost a year ago and find that I use it more than I ever expected... It's dead spot on as far as accuracy, easy to use, has a 'zero' button so it can be reset to cover most any project. The only draw-back that I have noticed is that it does eat up batteries faster than I expected. I made a habit of turning it off after each use although it automatically turns itself off after a few minutes of no use, and even then the battery only lasted about 6 months. Mine did come with a spare battery, and that was welcomed. Overall, a great product, a very good price when on sale for $20 or less and I would not hesitate to recommend this angle protractor to anyone that has a need for it.
