What matters most
What to consider
When selecting a wire tracer, start by defining the typical range you need. For residential work, a 50-100 m range is usually enough, while commercial or industrial settings may require 150 m or more. Consider whether you need a non‑contact voltage detection feature; this adds safety when working on live circuits without disconnecting power.
What to consider
Battery type and life are also important. AA‑powered models are easy to replace, but rechargeable units can save money over time if you use the tool frequently. Finally, look at additional functions such as continuity testing, metal detection, or built‑in flashlights, which can turn a single device into a more versatile troubleshooting kit.
