L1070 AND L1071 PORTABLE LOCATORS
L1070 Portable Locator

  • Multiple frequencies
  • Transmits AF or RF signals or both simultaneously
  • Peak and null detection
  • Passive 60 Hz
  • Measures current flow in buried conductors
  • Transmitter variable output power levels

Capable of locating long or short ranges, inductive or conductive, active or passive, the L1070 delivers quick and accurate results with a user-friendly interface. A special design feature on the L1070 allows the user to select and compare receiver information on two frequencies
simultaneously, without having to return to the transmitter. The L1070 features push-button depth measurements up to 15 feet to quickly identify service depths prior to digging. A passive 60 Hz detection services as an excellent safety feature for identifying live underground primary and secondary utility cables. An optional ground return probe allows ground fault detection on unshielded electric services or sheath faults on telephone services through the technique of voltage gradient.
