RIDGID 26168 ST-33Q
Line Transmitter

  • Distance: Induce over 8 times more current than the competition onto a target line. More current means that you can walk and trace further than ever before.
  • Versatility: Induces at 8 kHz and 33 kHz for low distortion locates. In direct connect mode, the SeekTech ST-33Q can transmit at any frequency between 10 Hz and 490,000 Hz making the RIDGID SeekTech ST-33Q one transmitter than can be used with all receivers.
  • Speed: More signal equals less retracing of your steps to pick up and move the transmitter. Cut your inductive trace steps in half, by only having to set up the ST-33Q once. In direct connect mode, the LCD display gives instant feedback on current flow and line resistance.
  • Accuracy: Induce more current at lower frequencies. Lower frequencies are less prone to jump onto other lines in congested areas reducing distortion and increasing accuracy.
  • Confidence: More current on your line means more signal to locate.
  • Compatible with the SR-20 Utility Line Locator and the SR-60 Utility Line Locator
