The RIDGID SeekTech ST-33Q+ is a powerful, multi‑frequency transmitter which can be used in conjunction with a RIDGID-SeekTech receiver like the SeekTech SR-24. Featuring Bluetooth, the ST-33Q+ is the ideal transmitter for inducing current onto a target line. It can 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 or 18V rechargeable RIDGID batteries for minimal interruptions on the job.

The new Bluetooth feature on the ST-33Q+ allows you to finish complex locates faster by wirelessly changing the transmitted frequency from the SR-24 receiver from up to 200 yards away.

  • Distance – Induce over 8 times more current than traditional transmitters. More current means you can walk and trace further than ever before.
  • Versatility – Power options include Lithium-Ion 18 V rechargeable battery, six D-cell batteries, or an external 10-28 VDC power source.
  • 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.
  • Speed – When used with a SR-24 Bluetooth®-enabled locator, you can control the ST-33Q+ settings wirelessly from the SR-24 reciever. Change transmitted frequency remotely from up to 200 yards away.

In addition to a series of default frequencies, the ST- 33Q+ can also accept custom frequency settings up to 490 kHz.
