Thanks for the input, Since nobody has yet to say that there is a better way to go than SURETEST, I guess I'll end up getting one. Probibly, when using it, I'll accept good readings, but if it reads FG (or anything other than good), I end up looking inside to see what is going on. Yes, it makes sense that if there are no grounds in the panel, or two prong outlets and 3 prong outlets, that something is up. I'm just thinking about a system where the BX or EMT is the grounding conductor. I think in that situation, there would be no possibility of false grounds, unless someone did some improper add ons using Romex or something else without hooking up a ground. Perhaps another scenerio could be EMT or BX pulled out of a coupling or connector, I seen that. Once again, thanks for the input, if anyone has anything to add, of course I'm interested.
