Triplett Fox & Hound Premium Tone and Probe Wire Tracing Kit Generates Multiple Tones with Adjustable Sensitivity for Electrical Wire, LAN Cable, Telephone, and More (3399)

Pretty fantastic tester compared to:(a) the price, in view of what my local supply shops were asking for similar Ideal and Fluke products (neither of which could do live circuits), and(b) my network cable tracer, which in the past has worked on AC wiring in a pinch, but doesn't have great rangeI used this unit to trace a ridiculously long bedroom circuit that had a mystery short. I traced something close to 200' of 15 gauge, including through a section of 18" concrete floor that has a 6-inch topping slab on 2 inches of foam insulation over it, and also through about 50' of 12 inch concrete wall, loaded with double rebar.Steering this probe requires a bit of patience, trial and error, and disconnecting a few junction boxes along the way. There's the potential for bleedover into parallel wires, and the signal will propagate through common neutrals (actually a good thing -- caught a few that shouldn't have been!), but with a little bit of attentive use it becomes pretty easy to figure out good from bad leads.As others have stated, NOT a good circuit breaker finder. It'll do in a pinch, but I recommend spending the few bucks on the dedicated tool if that's what you need.The live wire function works flawlessly, the tone generator is adequately loud and discernible, and I got much more use out of the continuity tester than I imagined, mainly because it was already connected to the wires, vs. disconnecting and clipping up my multimeter.So while this tracer doesn't work miracles and has a bit of a learning curve, it's really great at what it does, especially for the price. Wholehearted recommendation.

1. You need two 9-volt batteries.2. Pay attention to the lock button (see instructions)3. Practice using the Fox and Hound in all of the possible configurations on known circuits. It will save you time when you can't see any cables.Unlike so many other testers, the flexible design of the Triplet Fox and Hound means you have to know the nuances in order to get the most out of it. I first saw a Fox and Hound used around 1960 to trace underground wires and pipes. I was fascinated, but I can remember the electricians and plumbers talking about how proud Triplet was of their tool. Also, only one of them knew how to use it. The others were clueless.It is still well made, and I expect years of service.Read the instructions--the operating instructions. The way RF works will surprise you even if you are a HAM. I had cables from two circuits running very neatly next to each other for about 7 feet, and the RF propagated from the circuit under test to the second circuit. Since it was all in the wall, it caused some confusion in the attic when I started looking down a cable that I was certain was a different circuit. Also, a magnetic contactless charging unit was plugged in to the circuit under test, and It put a signal on the cable for some distance back that completely obliterated the warble. Finding and unplugging it resolved the problem. There are also hints in the operations instructions about how to ground the tester for underground RF detection. Save yourself some time and read the instructions first.Also there are different testing modes, and the section on "finding the NULL" is highly useful.Lastly, on the Hot-Wire version of the Fox, note that the selector switch locks in the "OFF - Continuity" position and to move it one must press the tiny red button just above the switch to move it.I love this system. Just stay calm and think about what it is doing, then read the instructions again.

Not powerful enough for tracing insulated wires under car plastic covers. 4* on easy to use because it lacks the long probes for hard-to-reach areas. Otherwise, great product from good seller with fast shipping.

A bit of a learning curve but it works great. So far it helps me with finding buried invisible fence wire to the inch accuracy, traced wires in conduit in walls and floors.

In my occupation as electrician

This device isn't worth a nickel let alone 150 dollars. I've tried a variety of experients since I couldn't track one wire attached to a switch. I was trying to figure out what the switch controled and thought this unit would do the trick; it doesn't.First, this device absolutely will not track anything inside of conduit. The metal shields the RF from getting through. The Fox device putting out the RF signal is not sheilded and therefore spills RF an an area six to ten feet in diameter. It would be what the RF world would call "dirty," very similar to raditation spilling everywhere. This spilling or dirt infect anything metal in the surrounding area and causes false signals in the hound.I've tried removing a wire from the switch and connecting the device directly to a dead wire. The unit spills so much RF that the "crosstalk"attaches itself to any wire in the junction, switch or outlet box and therefore shows up as RF at the next nearest junction box regardless of whether you have it connected to that wire or not making it completely useless for tracking.The only circumstance that I found where this unit would work is if you have a single wire running from point A to point B without any sort of metal around it. And if that's the case you certainly don't need a tracker to discover that.It might work if you have a single pair of wires running in a house that does not contain conduit, but since my house isn't wired that way I can't confirm even that operation.This is the most frustrating piece of test equipment I've ever used, and I'm a EE with a background in Ham radio since I was twelve years old. I've built better signal generations when I was that age than this is. I find it hard to believe that this piece of test equipment would pass FCC requirements for noninterference with other devices.

Me llegó un producto defectuoso, el día que llegó lo probé y le instalé pilas de 9V nuevas a cada aparato (Transmisor y receptor) y al probarlo como indica el manual, la batería en el tester del transmisor, nunca prendió el LED, probé con pila Duracell nueva y lo mismo. Lo devolveré

Good tracer , buy it !!!

Could not get a reliable result after many attempts. Waste of money.

Bought this to trace dead 120V AC branch in mid-century built house. Worked as expected and the sensitivity control allowed tracing of wiring embedded in walls and ceilings. Took about 30 minutes to locate the break. IMPORTANT!!! If you are tracing household AC wiring make CERTAIN the breaker for the dead circuit is switched off before connecting the fox device. If you have an intermittent break and you jiggle wires while tracing them you could apply full 120 or 240V AC to the fox, which will destroy it. The supplied case is a bit too small making it difficult to get the fox and its wiring in so you can close the velcroed flap.
