Thanks to several reviews here that described how the signal tone works (and of course reading the manual), I was able to locate the entire run. Not only that, but I was able to determine the depth - which at some points was more than 5 FEET below ground.When my contractor laid the water line, he did so in the same ditch as the cable. Since I was trying to find the water line (to add a tee so I could plumb the water into a new garage), I searched for the electric wires instead. By swinging the receiver antenna like a pendulum, I could hear the tone go silent each time it swung directly over the line. I then spray painted that spot, and repeated the process for the entire length up to the point where the garage was to be built.When I got to the point where I wanted to bring water to the surface, I marked the spot. I then held the probe in my hand, tilting it to 45° (you can use a carpenter's square to make sure the angle is precise). Then, I moved away from the spot listening to the tone. When the tone abruptly disappeared, I marked that location (which was 36" from the initial spot directly above the wire). Since I now have a right triangle (90°, 45°, and 45°), the distance between the spots is the same distance (depth) between the cable and the spot above it. I now knew exactly how far to dig down before encountering the wire. THat provide a reasonable level of confidence so I could swing my shovel aggressively until the last 6 inches or so.When I got to the suspected depth, I found the pipe and cable. It was perfect.The cables run directly under the pad for the new building. The pad, which consists of 14 dump truck loads of dirt to bring the grade up by 3 feet, put the cable 5' under grade. I did not think this device would scan that deep, but it did. And, as an added benefit, with the precise path and depth of the cable clearly marked, the building contractor can avoid hitting them when they dig their post footings. ### ⭐⭐⭐⭐ Works if you know how the tool functions. Needs a better manual. *by on Reviewed in the United States November 5, 2014* This is version 1.0 of the product and it has flaws, so be prepared. The instruction manual is a poor translation and appears to be written by someone who did not understand the theory of operation behind this device. That said, it can definitely serve a purpose. I traced out a 50 foot pipe buried about 14 inches down to an accuracy of a couple of inches. I used a nylon rope to show the precise path. The trick is knowing which mode to use. The device i have (October 2014) has a "battery test" position which is the position to use for sending a current through the wire. An LED lights when you have a closed circuit. So in order for directional mode to work, you need a closed circuit with the far end of the cable. A ground or large wire loop is OK if the return path is far from your wire of interest. The advertised workable depth of 3 feet seems correct. I think this will work on automotive wiring because regular steel did not seem to interfere with the RF signal. There is also an omni-directional mode where this unit functions much like a standard toner. You only need the red transmitter lead connected for this mode. If you have a broken wire this mode may help locate the break. ### ⭐⭐⭐ Throw away the documentation and read reviews posting on this site. *by on Reviewed in the United States April 4, 2015* Documentation sucks. Took me three days to figure it out. Here is what you need to know to track down an underground wire:a) SHUT OFF power to that wire. Buy one of those touch testers (lights up when wire energized) to be 100% sure. Is your life worth $26?b) Disconnect the black wire from your breaker box.c) Connect the red NF-816 wired) Here is the first trick: don't connect to the neutral or ground wires in the breaker box. Instead, get a long screwdriver and drive it into the ground outside. Get a long wire (mine took 30' of wire to get outside) and connect one end to the screwdriver and the other to the black clip from the NF-816. Make sure your dog/kids don't trip over that wire, it would mess with your head...d) Turn on the NF-816 to max volume and max Cable Teste) Take the remote part of the NF-816 and go outside. Turn it on on max, don't use the headphones (unless you want to go deaf)f) Here is the second trick: it makes crackling noise all the time, various sounds, burps and other insanity. Once you are above the wire it goes silent. Go back and forth, you'll find the wire.g) Here is the third trick: depth? Never figured it out, I just dug until I hit the conduit. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1401791-noyafa-nf816-new-genuine-underground-cable-wire-locator-easily-locate](https://www.desertcart.tn/products/1401791-noyafa-nf816-new-genuine-underground-cable-wire-locator-easily-locate) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-30*
