SureTrace Plus サーキットトレーサー 0-600V AC/DC

I recently began upgrading the wiring in my house. The previous owners had added a number of circuits to existing wiring which made it extremely difficult to follow. These tools make it easier and much safer to do the work. I feel that although they may seem expensive they can potentially save your life and also save you a lot of money.

Pro grade tool. There is a small learning curve and to understand the instructions clearly you need to have a understanding of electrical theory. Don't be scared...it is not difficult: hot (black), neutral (white), ground (bare). This tool tracked a mysterious line through walls and found the cross connected breaker. Paid for itself not hiring a electrician and a helper in one use. If you have a older home with mysterious switches and breakers this will solve the mystery. Just make sure you follow electrical safety protocols and you will be fine.

Great for the money, not as stable as the big brother. I've used the $1500 version and this one. The more expensive one is definitely better but this one is good enough. This one is more excitable than the calm big brother. I actually have to turn down the sensitivity a lot most of the time. It'll give me a false positive initially and I have to wait a split second before it'll calm down and give the accurate reading. It may not be as pinpoint accurate as the two-receiver version but I'm OK with that. This one is accurate enough. The ability to trace a dead circuit has saved me days worth of time.

Absolutely AMAZING!!! Exactly what I needed for a job, I contacted seller ahead of time and asked for even faster shipping. They got it here FAST!!!!! THANK YOU SO MUCH!!!! Also, product worked great, and is exactly what I wanted

It works by injecting a specialized AC signal onto the conductor, and even when the wire is “open,” the signal still forms a usable return path through the environment because every conductor in a building has capacitance to ground, neutral, nearby wires, or the building structure, creating what the SureTrace manual calls a remote return path that completes the loop electromagnetically rather than through metal conduction, allowing a tiny AC displacement current to flow even across openings where DC or 60 Hz AC would see an infinite break; this current—although extremely small—creates a magnetic field that the receiver detects, because, as the manual notes, the transmitter “emits a signal onto the conductor and the receiver senses the strength of that signal” and the “remote return path” enables tracing when the transmitter cannot rely on normal conductive continuity; importantly, while capacitive coupling means some of the signal leaks weakly onto other conductors, only the intended wire carries the dominant current because it is directly driven by the transmitter, while all other wires receive only tiny parasitic currents through high‑impedance capacitive paths, producing magnetic fields that are orders of magnitude weaker, allowing SureTrace to reliably identify the correct conductor by simply detecting the strongest magnetic field signature, consistent with the manual’s instructions to scan for the highest reading when locating the correct breaker or wire. This thing operates based on magnetic field detection which is key difference from Klein ET450 (electric field detection) - what difference? ask AI!
