Calculated Industries 7489 AccuMASTER Value Pack – 2-in-1 Digital Angle Gauge plus the Digital 7-Inch Angle Finder Ruler | Accurate Precision Tools for Carpenters, Woodworkers, Fabricators | 2-Pieces

So far so good. It’s quite accurate except 2 issue. The 2 rule don’t seem to exact width size, hence not parallel depending on which side (inner or outer) I take as reference point to reset zero. Second issue is the reset button can be easily press by accident. Should make it press and hold to reset for example

These both work great. Once you zero out the finder on your saw, then find the angle on your blade it works great. Very happy with these. Use the magnetic finder on my table saw blade the most, easy to set up and read. Do not know how to test for angle accuracy, but I did use the magnetic finder to set an angle, then used the ruler finder to check that angle and it was bang on.

The level 8s awesome. I love the bright screen and the magnet on it means I can perfectly square my table saw and mitre saw blades with ease. The angle finder also makes it a dream to do trim work and cut "45s" on off angle walls. These are both very easy to use and worth every penny. also they are one of the few that at least advertise a case to keep them clean and protected when not in use. highly recommended.

Easy to use and very accurate.

Just junk. Protractor quit after using 9 times over 3 month period, then find out my return window closed a month after I bought it. Just junk.
