Description
The FNIRSI WD-02 is an upgraded version of the WD-01 wall detector scanner, featuring a high-definition colour TFT display and a redesigned UI that makes on-site scanning faster and more intuitive. Building on the same HPC detection module foundation as the WD-01, the WD-02 adds three dedicated detection modes — Metal, Wood, and AC Wire — allowing the operator to select the specific scan type required rather than relying on a single auto mode. It detects ferrous metals (rebars) up to 120mm deep, non-ferrous metals (copper) up to 100mm, live AC wires up to 50mm, single-strand copper wire up to 40mm, and wooden studs up to 38mm in Depth mode. The screen displays target depth, material type, and centre position simultaneously, while the three-stage indicator ring — green (clear), yellow (approaching), red (at centre) — provides instant visual position feedback during scanning.
The WD-02 also introduces 3-level sensitivity adjustment and automatic calibration, allowing accurate detection across different wall surfaces including painted walls, wallpaper, acoustic ceilings, wood flooring, and lath. Six language options are supported — Russian, English, Portuguese, Japanese, Simplified Chinese, and Traditional Chinese — broadening its accessibility for international professional teams. The device retains the centre positioning hole design that allows users to mark the drilling point directly through the body of the scanner, the 3.7V 300mAh rechargeable lithium battery with USB Type-C charging, and the auto shut-down after five minutes of inactivity. At 138 × 68 × 22mm and 122g, the WD-02 is identical in physical footprint to the WD-01 while delivering a meaningfully more capable scanning experience.
For electricians, civil contractors, interior fit-out teams, and DIY homeowners across Pakistan, the FNIRSI WD-02 provides a practical, safety-critical tool for pre-drilling wall inspection. In Karachi’s residential and commercial construction environment — where embedded conduit wiring, copper plumbing, and steel reinforcement within concrete or block walls are standard — the WD-02’s three dedicated modes, colour display, and sensitivity adjustment make it a more reliable field tool than basic single-mode detectors.
Why Choose the FNIRSI WD-02?
The WD-02’s key advantage over the WD-01 is its combination of a colour TFT display, three dedicated detection modes, and 3-level sensitivity adjustment — features that meaningfully improve detection reliability across Pakistan’s varied wall construction types. Whether working on a Karachi apartment’s plastered brick walls, a tiled bathroom, or a commercial office fit-out with gypsum partitions over concrete, the ability to switch between Metal, Wood, and AC modes and adjust sensitivity for the surface material at hand gives the WD-02 a decisive practical edge. The automatic calibration feature is especially useful for technicians who move between sites and surfaces throughout the day, as it removes the need for manual baseline setting on every new wall.
FEATURES
- Upgraded high-definition colour TFT display with redesigned UI shows target depth, material type, and centre position simultaneously for clear, at-a-glance readings during scanning.
- Three dedicated detection modes — Metal, Wood, and AC Wire — allow the operator to focus the scan on the specific target type, improving accuracy and reducing false positives.
- HPC detection module provides superior anti-interference performance and faster signal calculation, maintaining reliable results near sources of electromagnetic interference such as microwave ovens and high-current wiring.
- Three-level sensitivity adjustment allows the user to tune detection performance for different wall materials and construction types, from dense concrete to plasterboard and acoustic ceiling tile.
- Automatic calibration on any wall surface simplifies setup and ensures accurate detection without manual baseline adjustment each time.
- Three-stage indicator ring — green (no target), yellow (approaching), red (at centre) — delivers instant visual proximity feedback during scanning.
- Audible beep on target detection with continuous alert when the scanner is directly over the detected object’s centre for precise location confirmation.
- Centre positioning hole in the device body allows the drilling point to be marked directly through the scanner immediately after detection, eliminating measurement transfer errors.
- Detects and works on a wide range of wall and floor surface types including painted walls, wallpaper, acoustic ceilings, lath, wood flooring, and tiled surfaces.
- Six language options: Russian, English, Portuguese, Japanese, Simplified Chinese, Traditional Chinese.
- Rechargeable 3.7V 300mAh lithium battery with USB Type-C charging; auto shut-down after 5 minutes of inactivity.
