Review on Inclinometer RISEPRO Protractor Backlight 82413B by Patrick Diaz

One-piece extruded aluminum body, nearly correct resolution and accuracy for basic machining settings - if you need more precision get a sine bar and calibration blocks. It's damn big, it feels like the size of a mid-90's cordless phone in my hands. One catch - there is a screw on the battery cover. I took it to my lathe already leveled with a Starrett 98-6 precision level and this showed 0.00 degrees out of the box. However, I wouldn't recommend using this to level a lathe unless that's all you have. It took me a few minutes to adjust the adjustable 45 degree angle plate and the setup was as good as I could tell by eye. with a machine angle.
