It is just so nice to get a digital reading doing construction jobs. Having a zero button means I zero on the table of my not so level 'she shed' shop and then set the blade angle without squinting under the table at little radial lines. It's magnetic for steel surfaces. There are ones with more features, but this does fine and was cheap. I love that these kind of items get posted on Facebook. I check it out, get sticker shock, and come to revain and pick it up for a fraction.
