Product information
FNIRSI WD-02 wire detector.
Before you put the drill to the wall, make sure you know what's behind it. The FNIRSI WD-02 wire detector is a reliable tool for do-it-yourselfers and professionals to avoid accidentally drilling through wires, pipes or structural components. The device offers three precise detection modes (metal, live cables and wood), allowing you to effectively locate various materials hidden in walls, floors or ceilings. Thanks to an advanced HPC chip, the detector has increased sensitivity, speed and accuracy, and the detection range reaches up to 120 mm - much more than standard drilling depths.
Three modes of operation, multiple applications
The FNIRSI WD-02 allows you to freely switch between three modes depending on your current needs. Metal mode detects both magnetic metals (steel, iron) and non-magnetic metals (copper, aluminum). Cable mode identifies live cables hidden in walls, and depending on the material, can also detect unconnected wires. Wood mode can find wooden parts and other objects hidden behind drywall, including light steel parts, nails or pipes. It's a versatile solution for home, renovation, installation, as well as construction and road work.
Advanced screen and precise navigation
The device is equipped with a TFT HD color screen with a clear and intuitive interface. The data on the screen is presented clearly - indicating the depth of the target, its position relative to the center and the type of material detected. In addition, light indicators (green, yellow, red) and sound signals inform about the approach of the target. Precise positioning is also possible thanks to adjustable sensitivity - the lower the sensitivity, the higher the measurement accuracy.
Compact, robust and ready to use
FNIRSI WD-02 is a well-thought-out device in every respect. It has a non-slip side texture, an impact-resistant ABS housing, buttons with a pleasant silicone finish and a panel made of transparent acrylic. The built-in 300 mAh lithium battery eliminates the annoying need to replace the battery - just charge it via the USB-C port to enjoy long use. Support for six languages (Russian, English, Japanese, Portuguese, Traditional Chinese and Simplified Chinese) makes the tool ready to work in a variety of conditions and environments.
