Though I have a real nice manual tachometer in a fitted case, this is SOOO much easier. Don't have to futz with cranking the head up far enough to stick the spindle tip into the collet to read RPM...
Do you think it is different than this one from Harbor Freight?

Looks like it is order only, number didn't come up when I searched the stores site.
Not entirely sure, but here's the looser's manuel in chin-glese.
I'll have to keep my eye open for this to come up via a discount at HF when I'm feeling flush. It would be handy to have now and then to check stuff. If you're struggling to find differences between the two it is most likely the same unit. Grizzly does a much better job of glitz and glamour promoting their stuff, but it still comes from the same source.
