Review on GemRed Digital Depth Height Router by Brian Campbell

I use this to calibrate the height of a table saw blade. Check the depth of the incisions and dado. I also use it over my table saw blade with the tip against the fence to measure the width of the cuts from the edge of the board when making dados. I add the width of the blade I'm using to the gauge when cutting strips of a certain width from a larger board. Makes it easy to be consistent from one job to the next.
