Talk:Underground Wire Locator
I'll ask about these when i'm back at work. One of the guy's Multimeter may have had a feature for this? Also i'll ask how often they deal with Tracer Wire, granted most stuff is Rewiring Jobs (old shaks with cloth and/or latex coated wires that disentigrate when you touch them, or Knob and Post Wiring , that and (Commercial) Renovation work / service calls) so they may not deal too much with this. Although i was hearing some story involving a Trencher so potentially.
Either way i'll ask around, and if i get any useful information i'll add it to these pages.
