The height gauge looks like the HF model I have. I also have the Tormach gauge but have never used it as was not impressed by the looks either. Ha, forgot about even having it until I read your posting.
The HF gauge works pretty well and I like the carbide indicating bit that came with mine for scribing parts. The battery does not last all that long as with most of the Chinese indicators but that is my only gripe. If I remember right paid about $70.00 for mine a few years back.
