Works well but can be found for much cheaper.
This device works good for locating non-energized wires that are buried in the yard (sprinkler wires, cable TV coaxial wire, and invisible fence wires) It is made in China so quality is mediocre but it does work as advertised and is much cheaper than other comparable wire locators. If you use Google you can find it much cheaper as long as you are willing to have it shipped directly from China (delivery time is about 2 weeks) Just Google the model number as your search criteria (NF-816) and you'll find it from several overseas vendors for about 1/2 the price anywhere here in the U.S. For the price I paid ($58 plus $15 shipping) I am satisfied with my purchase.
To use it you hook up the red lead of the transmitter to one end of the wire you are tracing and then attach the black lead to a screwdriver shaft that has been driven into the ground which will ground the circuit. The transmitter will emit a signal that can be then be traced by the locator device by moving the receiver back and forth about 6 inches above the ground. It takes some practice to tune the receiver in but once you do this tracing the wire is quite easy. I was able to practice by taking an old scrap piece of wire and just laying it on top of my lawn and then hooking the transmitter up to it so I could see the wire while experimenting with the wire locator.

I needed to locate an underground conduit with #12 electric wires in it. After digging around and trying to track the conduit back with no success, I decided to try this product. Within 20 minutes I had located the 3/4 inch pvc conduit about 30 inches deep. The instructions are lacking but this is what you do:
First, after attaching the transmitter to your un- energized wire, roughly locate the conduit by holding the receiver vertically a few inches above the ground. Don't let it touch the ground as this will give a false signal. Note it is not as sensitive thru pavement or concrete. This will get you in the ballpark but could be an area 6 or more feet wide. Next, zero in by holding the receiver at a 45 degree angle and come in from each side of the general area you have found. Point the receiver at 45 degrees towards the area identified. When the signal is first heard, put a stone or stick at the point you first hear the signal on each side of the general location identified. Once you have marks on each side, dig in the center between the marks. The distance between marks is roughly the depth to the conduit, giving you some idea how deep you need to dig. The signal will be coarse and sound like static as you are roughing in the location. As the receiver gets very close to the conduit, the sound will become clearer, with less static. The clearer the signal, the closer you are to the conduit.
Although I have only used this once, it was better than spending hours looking for the conduit by digging random holes, or hiring a backhoe to come in and find it, most likely damaging it. This is a homeowner quality instrument but it does work and is worth the money.

Accurate and Time Saver
By J. E. N.
I've been through it before. Underground dog fence breeched somewhere and I spent hours digging if up, testing, redigging, and some of my wire goes through the woods. NOT THIS TIME. This device was easy to use and accurate. Simply disconnect the loop where it starts after the twisted-wire connection and hook up one part of the loop to the transmitter--this now turns the loop into an antenna. Walk with the receiver to follow the underground wire. When you reach the break, the signal disappears. Expecting to spend a day finding the break, I was amazed to accurately locate the break to within 2 inches, dug down (through leaves in the wooded area) and there was the clean cut through the line! Some animal or what??? Repaired, tested, worked, all within 15 minutes. Well worth it's money. I'm almost looking forward to the next break. Biggest tip: when you locate the underground wire, swing the receiver back and forth over the area slowly like a pendulum. The signal briefly disappears EXACTLY over the actual wire location. Great if you need to mark the line for digging notifications.
