Review on Mastech MS6812 Telephone Tracker Network by Darina Chomutrov ᠌

For dialing, you need to turn off all the electricity, otherwise you will only hear 50Hz. The first detector may have been expecting the impossible. Got pros: There are both dialing and wiring detection. Grinding in the extension cord finds at a time. Cons below: In the walls he is looking for very approximately (15-30 cm). If there are several wires, nothing is clear at all.
