Title: A bad joke
Product review: This "detector" has absolutely no capability for tracing voltage or current through walls-- just get that out of your head from the start. there are a few situations where this detector might work, but many more where it simply doesn't.Take a simple example. I wanted to see if a an outlet had power. The outlet located a few inches from the first had power and threw off enough EM signal so that I couldn't tell if the outlet in question was powered. When I shut the second outlet off, I could then test the first.bottom line, this is no better than the $5 detector available at any hardware store.
