To be honest I would not buy this guage. while it is a good idea, the design leaves it vulnuable to getting bent and out of adjustment. I looked at it at the trade show this last year and decided that the old flat bar adjustment is a far better method of setting your verticutters. To start off with, who needs to be within .001" of a height for verticutting. Take the flat bar, draw a line at the height you want and set each side of the verticutter to the line. if you want to get more accurate, get a machine shop to grind out the amount you want from an edge of the bar.
