The DD130 locator utilises power, and radio modes. This means the locator can be used without the transmitter to find power lines under load and potential metallic lines. When used with a transmitter additional metallic lines can be located, and depth measurements can be taken. The DD130 also includes the additional features of current measurements, and lower frequency which aid in long distance tracing and identification of sewer cameras.
