Thanks for the advice. Sounds like it's not worth it to get the new gauge since I can get the Batgage to work with good results. I too find that you must make sure that the left side of the gauge is completely flat against the blade. I also make sure to check that there are no fibers (after I wipe finishing oil off with a rag) or any burrs, hairs, etc on the blade, as those foreign materials could throw off the gauge significantly.
