Frequently Asked Questions

AI
Stud finders primarily detect wood or metal studs behind drywall, often with basic AC wire detection. Dedicated cable detectors or wire tracers offer deeper penetration, better accuracy for identifying live wires, and can trace cables through walls or underground, making them more suitable for complex electrical troubleshooting.
Most standard non-contact voltage testers and basic stud finders struggle with concrete. However, advanced underground cable locators and high-end wall scanners with deep-scan modes can detect metal conduits and live wires embedded in concrete, provided the signal strength is sufficient and the wall thickness is within the device's range.
Yes, for accurate underground tracing, you typically need a transmitter that connects to the cable end to emit a signal, paired with a receiver wand to track that signal. Some all-in-one units combine these functions, but dedicated systems offer greater range and precision for long-distance or buried line detection.
