Review on Colfuline Protractor: Precision Tool 📐 for Woodworking & Construction with Neodymium Magnet by Charles Collier

I never considered the need for a digital level so we decided to measure the angles on our Adirondack chairs. It's almost impossible without it. The plane itself is 15-¾" long, 2-½" tall and 1-1/16" deep. It appears to be aluminum with plastic inserts. Ribbed finish, the bottom has ribbing along the outside edge with a V -shaped insert in the middle. This groove is magnetic. The outer edges are rounded in rubberized plastic to prevent being used when measuring. There are two traditional spirit levels, one at the long end, the other vertical and plugged in. The horizontal one has triple lines, the vertical one has double lines a black zippered pouch on one of the narrow ends It had a handle on the long end Level controls: ****On/Off/Beeper**** Null**** mode : Angle, Slope, Inches/Feet, mm/M**** Hold Get a visual indication of the measurement direction from horizontal with a graphical readout on the display and an arrow This comes in handy when you are close to zero The scary part is that I use it now on many surfaces use which I have defined as layers that are no longer there. They are less than 1 degree but now I know. I didn't understand what the handle was for until I used it. It saves readings in case the level is in an area you can't see. So you can hold it down and then read it. You can use zero to get a relative angle of something. If I had played with it beforehand, I might have saved some math. All in all, it's a handy tool that I never knew I needed until I needed it.
