AG-309.15G is high-precision utility locating instrument. It is a result of 30 years of TECHNO-AC experience in underground cable & pipe location.

This utility locator features large LCD display which indicates actual position of cable or pipe. Moreover, after locating the position, an operator can measure burial depth of located utility without pressing any buttons and store GPS coordinates of located utility.

This model is equipped with 20 W transmitter. It is twice powerful in comparison to other brands. This particular model allows to trace underground cables & pipes up to 3 kilometers. However, this distance can be increased up to 10 kilometers by using more powerful signal transmitter.

  • Monoblock receiver AP-019.3 with built-in GPS/GLONASS module.
  • 20 W AG-105 transmitter.
  • High precision location of underground utilities up to 10 m.
  • Direct digital measurement of cable current up to 10 amperes.
  • Location of non-conductive and non-metallic utilities with optional pushing rod and pipe sonde.

Locator supports most required utility connection methods

  • Direct connection with crocodile clamp (pipe magnet is supplied in standard set).
  • Wireless induction with antenna, built into signal transmitter.
  • Clamping.

Brief description

  • Three modes of operation: "ROUTE”, "GRAPHIC”, “FRIEND-OR-FOE”.
  • Three inbuilt sensors make omnidirectional antenna showing a direction of a cable or a metal pipeline on LCD display.
  • Inbuilt sensor for digital measurement of the depth and current.
  • Measured depth is 10 m.
  • Passive frequency: Power, Radio, BB.
  • Active frequency: 512 / 1024 / 8192 / 32768 Hz.
  • Sensitivity: 100 μA.
  • Large LCD display with high resolution and adjustable backlight brightness.
  • Transmitter 20 W.
  • Cast body: the case is sealed along the entire length to the connectors.
  • GPS/GLONASS module for accurate positioning of the located utility.
  • Mini-USB cable and desktop software for uploading and processing the data from the receiver.
  • Warranty 1 year.


  • Detection of cables and any metal pipelines underground up to 10 m.
  • Direct digital measurement of the depth up to 10 m.
  • Indication of the deviation from the utility axis in the mode “ROUTE”.
  • Direct digital measurement of the current.
  • Survey the ground before the excavation works.
  • Tracing of undergroune utilities at distance up to 3 km.

Optional application

Location of cable and pipe insulation damages with contact and non-contact method using external sensors DKI-117 and DODK-117.
