Pipe & Cable Locator (vScan & vScanM)

The vScan and vScanM Pipe and Cable Locators are electromagnetic detection instruments used to trace the underground route and depth of buried metallic pipes, electrical cables, and communication conduits without excavation. These tools prevent accidental strikes during ground-breaking operations at construction sites, utility maintenance work, and security infrastructure installation projects across Pakistan’s urban and industrial environments where dense underground utility networks create significant dig hazard risk.

The locator system operates in two components: a signal transmitter that induces an electromagnetic signal onto the target conductor, and a receiver wand that detects the emitted field above ground as the operator walks the suspected utility route. Active signal induction connects through direct clamp attachment to an exposed conductor section or through inductive coupling from the transmitter placed above the buried line without physical contact. Additionally, passive detection mode allows the receiver to locate live electrical cables and metallic pipes carrying their own electromagnetic emissions without transmitter deployment, useful for rapid line tracing when transmitter access to the conductor is unavailable.

The vScanM variant adds a built-in data logging and mapping function, storing depth readings, signal strength values, and GPS coordinates at user-defined intervals during the survey walk, producing a spatial dataset for post-survey utility mapping and GIS integration. Furthermore, operating depth range on standard models reaches 5 meters for single conductor targets under favorable soil conductivity conditions, with accuracy degrading in highly conductive soil types such as wet clay common in irrigated agricultural regions of Punjab and Sindh. Frequency selection covers multiple bands between 50 Hz and 200 kHz, with lower frequencies providing greater depth penetration and higher frequencies improving signal isolation on congested utility corridors.

Display output on the receiver unit uses a bar graph signal strength indicator with depth readout in centimeters, and an audio tone that changes pitch with signal intensity to guide the operator along the utility route without requiring constant display viewing during the survey walk. Moreover, battery operation on AA alkaline or rechargeable NiMH cells provides 20 to 30 hours of continuous receiver operation per charge.

Tactical Supply Pakistan supplies vScan and vScanM Pipe and Cable Locators to civil engineering contractors, utility maintenance teams, telecommunications infrastructure operators, and military engineering units requiring reliable underground utility detection capability across Pakistan’s construction and infrastructure sectors.
