RIDGID's SeekTech SR-20 new line of locating equipment meets the most demanding needs of the locating professional. Built to make even difficult locates easy, SeekTech SR20 is the only line locator that uses omni-directional antennas, guidance arrows and an easy to read mapping display to lead you quickly and accurately to the target line.

The antennas power the large mapping display which provides all the information you need to locate underground utilities with ease and confidence.

The Mapping Display confirms a good locate signal and identifies distortion in congested areas using:
  • Target Line – Guides the operator down the line and shows changes in direction.
  • Left-Right Guidance Arrows – Point the operator to the target utility.
  • Proximity Signal and Signal Strength – Helps the operator center the locator closer to the target for more confident locates.
