Review on Accurately Measure Angles And Levels With GemRed XVB Digital Gauge Level Box For Pipe Conduit by Joshua Follansbee

I bought this digital angle reader to adjust my miter saw. The idea of this tool is great. But in practical application it proved to be not so useful. Its bottom side is only side that is magnetic. To adjust the vertical angle of the blade one has to put it on the table surface of the saw and zero it in that position. Then you flip it 90 degree and attache it to the blade with a power of the magnet. At that point the tool gets "confused" between negative or positive angles of the blade. And the digits on display "jump " from positive and negative too, making it hard to understand which way to adjust the blade. It would me good if the tool had magnetized its vertical sides too, so the reading would be closer to the zeroed number.
