Ridge Tool ST-33Q super-induction transmitter

Ridge Tool has introduced its ST-33Q super-induction transmitter, which is designed to be used with Ridgid locators to trace underground pipe, cable and other metallic lines. When used in the induction mode, says the company, “the ST-33Q induces at 8 kHz and 33kHz”…and can provide more than eight times the current on the target utility, compared to 5- and 10-watt transmitters. The ST-33Q has six preset frequencies that can be used directly when connected to the target, says the manufacturer, and in addition, end-users have the ability to set their own frequency.
