Throw away the documentation and read the reviews posted on this site.

Documentation sucks. It took me three days to figure it out. Here's what you need to know to trace an underground wire: a) DISCONNECT power to that wire. Buy one of these touch testers (lights up when the cable is live) to be 100% sure. Is Your Life Worth $26? b) Disconnect the black wire from the control box. c) Connect the red wire NF-816) Here's the first trick: Don't connect it to the neutral or ground wire in the switch box.

After setting it up, it took me about 10 minutes to accurately locate over 200 feet of underground cable. I think some of the negative reviews are due to operator error, meaning they didn't understand how this device was supposed to work. I found that it actually works two

Pros
  • Quality construction
Cons
  • Requires an outlet
