ST-33Q Transmitter

The RIDGID® ST-33Q Line Transmitter is the ideal transmitter for inducing current onto a target line. It will also direct connect using any frequency from 10Hz to 490kHz* with power up to 10 Watts. The ST-33Q also allows the flexibility of using D-Cell alkaline batteries.


  • Distance – Induce over 8 times more current than traditional transmitters.  More current means you can walk and trace further than ever before.
  • 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.


  • Frequencies
    • Direct Connect (pre-programmed): 128 Hz, 1 kHz, 8 kHz, 33 kHz, 93 kHz, 262 kHz
    • Direct Connect (user programmed): Any Frequency from 10 Hz – 490 kHz
    • Induction: 8 kHz or 33 kHz
  • Other Specifications
    • Max Power: 10 watts
