Lightweight yet rugged, the RIDGID SeekTech SR-20 Underground Locator provides utility-locating professionals with the information needed to effectively determine the position of underground utilities. Its omnidirectional antennas measure electromagnetic signals and calculate the signal's orientation strength, depth and degree of distortion or interference. For added on-the-job confidence, the utility locator features a target line and guidance arrows that quickly identify distortion to avoid mismarking.
