ST-305 Transmitter

The ST-305 will clip to or magnetically attach to any conductive material (pipes, wires, tracer lines) and transmit a signal that the SR-20 or Navitrack can identify with the corresponding frequency. We have identified signals from 500’ away, 8’ deep!!


  • Direct connect using attached clips
  • Induction from optional inductive signaal clamp
  • Induction from the transmitter coils
