Device for detecting live wires, ferrous and non-ferrous metal objects, which also features a laser distance measurement function with a maximum range of 40 meters. 

It has the ability to detect ferrous metal objects (e.g., iron rod) at a depth of 100 millimeters, non-ferrous metal objects (e.g., copper pipe) at a depth of 80 millimeters, live wires at a depth of 40 millimeters, and can even detect wood at a depth of 38 millimeters.

During detection, if any of the above materials are detected, the screen indicates the depth along with audible alerts. If a live wire is detected, a special indication on the screen warns you of the risk of electric shock if you drill at that point.

The MK2101D detector can measure with an accuracy of ±5 millimeters, and the distance to a targeted object, as long as it is within 40 meters.
