Great link Redsy, it was interesting.
I think Bjarney's post in that thread bares repeating.
Use *any* voltage tester with an clear understanding of the device's limitations, and when it is likely to give false readings (or no reading). Experience is a good teacher. The concept is valid and used just about everywhere—a lot of utilities use devices like Modiewark testers at 230kV+. There are no absolutes in this world. We take risks every day, but mostly they are ‘informed’ risks—there may be consequences. The non-contact tester increases job safety, but know when to question its readings—where another type of tester may do a better job.
While I do use my non-contact tester to verify things are dead I am also aware of it's limitations.
