Review on Precision Measuring Made Easy With GemRed Digital Tool Set For Table Saw - GR905 Angle Gauge GRSET905 by Kevin Phillips

Got this for a 1960's Craftsman 10" table saw 113.29992 I just restored. I knew I could set the blade angle with a square, but I wanted to make sure I was accurate, and I plan on doing some projects that will require some odd and precise angels. This works just like it says. And I love the zero feature, as my garage floor is not close to even, so I can set zero to the table saw top, then put it on the blade and set my angle. It does take 1-2 secs for the readout to adjust and settle, but when it does, it's dead on. I even take it off and re-zero to table top, then back on to blade just to double check, and it's always exactly the same reading.
