I bought it again after the refund. The previous one had an irreparable problem during the warranty. It is quite effective.

Quite a good detector. The instructions need to be read. I was unlucky because after a while it stopped working...... The generator was working but it wasn't producing a signal on the cables... I opened it. And in the end, there was a loose screw behind the panel. It wasn't making contact. I tightened it and everything is fine

Useful tool for any electrician. It helped me locate a damaged line easily, detecting up to 80 meters deep.
