1. Multi-functional detection: The wall detector can detect and locate wires, pipes and metal materials in the wall. When using it, you only need to point the detector at the area to be detected and scan to obtain detection results quickly and accurately. 2. Large detection depth: For magnetic metal, the detector can detect to a depth of 110 mm, for non-magnetic metal, it can detect to a depth of 80 mm, and for charged wires of 110~230V (when the voltage is applied), it can detect 50mm depth, wood can be detected to a depth of 35mm, supporting depth detection. 3. Automatic shutdown: The detector has an automatic shutdown function. When the detector is not operated within 3 minutes, it will automatically shut down to save battery power, which is convenient for users to use for a long time. 4. Wide application range: the detector can be widely used in construction, decoration, pipeline maintenance and other fields, helping users to quickly and accurately detect the position of target materials during operation and improve work efficiency. 5. Portable and easy to carry: The detector adopts a small and light design, which is easy to carry and store, and can be used in various occasions at any time, and the operation time is about 6 hours, and the service life is long.
