It is dangerous to be reliance on these fancy gadget... Due to components failure... You take for granted that the line has no power and may get injured/killed. It is OK to use it as a first line of detection with follow up checking and comfirmation with a normal standard test pen as before touching the power line. Personally, I use the best quality test pen for checking.
Thank you for your precious experience. These are the tests that can be done only for interesting tests on broken wires and on DC currents and possibly unsafe with ac power under direct test. But it was still an enjoyable experience. Once again, thank you for your comments
