Main Functions: 1. Line finding function: It can directly search for underground metal cables, and can search for RJ11, RJ45, BNC interfaces through adapters. 2. Digital/analog line finding function: It can locate metal wires (including power lines, telephone lines, and network lines) buried underground or inside walls. 3. Continuous (path) detection of wires. 4. It has a low voltage prompt function. 5. The receiving end has a lighting function. Characteristic: [Efficient]When searching for cable lines, there is no need to peel off the outer skin of , it is simple and fast, and the location of line breakpoints can be identified. [Underground cable detection]Detect the direction and positioning of cables buried underground and on walls, with a detection depth of up to 2 meters. [Lithium battery]3.7V/1000mAh lithium battery, type-C USB, and environmentally friendly [Dual mode line finding]Digital signal line finding: Strong anti-interference ability, more accurate line finding without noise. Analog signal tracing: With a wide range of receiving signals and strong sensitivity, the tracing range is larger. [Adjustable transmitter transmission signal]The signal strength can be adjusted from 1 to 5 levels for more precise line finding, and suitable signal strength can be for line finding. Technical Parameters: Working temperature: 0-40 ° C, maximum relative humidity of 80% (non condensing). Storage temperature: -10~50 ° C, maximum relative humidity of 80% (non condensing). Digital line finding distance:
