What is the maximum depth this will locate underground wires?

Asked by: Dennis
This probably isn't the right tool for this application. If you need to locate/trace underground wires and cables you should probably be looking at a signal tracer/signal locator. And unfortunately you'll be looking at a significantly more expensive device.

Rated 4 out of 5 by from Tone probe usage Takes getting used too. Will tone the wire in a bundle but it's difficult to actually tell which wire in the bundle is the one. But it does get you in the ball park and if the wire is open you can tell about where the open is. Again, it takes some patience and trial and error. But without it your goose is cooked.

Rated 4 out of 5 by from Good generator/probe kit I used this tone generator and probe to work on a structured wiring cabinet project to identify phone, cat5e and coax cable runs. It worked great in all cases. Overall quality of the devices are good, but I did have some difficulty installing the 9v batteries (which are included) into the compartments. The internal wiring inside the cases got in the way and the wires on the battery caps could have a been a little longer to allow the batteries to be inserted easier. The tone generator has plugs for phone, RJ45 and alligator clips which is used to clip onto the coax cable. It also has a switch inside the unit that can select between continuous or pulse tone but it would be nice to have this on the outside of the case. The probe is ergonomic and has a volume adjustment nicely located for easy thumb adjustment. I found that the sensitivity was very good and easily identified the proper cables, even for long runs from the second floor. Overall it's a good basic probe, but not an all-in-one like other models. But for me it does the job.
