Is there such a thing as going too far? That’s a silly thing to ask a Toolmonger, the answer is almost always no. So it stands to reason that even the guys out there that haven’t upgraded to newer saws should be able to have digital precision on their saw blade and avoid seeing light between your square and your table saw blade.
This digital angle gauge coverts all the late-adopters to the new “digital age” with a small tri-corder-looking devise that sticks (via magnets) to the blade of your table saw. It does require a small calibration to the flat part of the table to find the zero angle first, but after that you can stick and adjust the angle of your miter or table saw as you see fit.
As digital conversions go $40 isn’t bad — especially if you factor in the cost of replacing your old saw for a new digital one. When “close” isn’t good enough — or you’re not big on the use of uber amounts of putty — accuracy now comes in easy to use 0.01 degree increments.
