The RIDGID Seek Tech SR-20 Pipe Locator features an easy-to-use visual mapping display that allows you to locate utility lines and sondes/beacons with confidence. Use with a See Snake camera equipped with a sonde transmitter to locate the camera head during an inspection or use with a line transmitter to find buried utilities. This underground wire locator can also find flushable float sondes and remote transmitters attached to a push rod or drain cable. Seek Tech underground wire locators provide unprecedented ease-of-use for locating underground pipes. Transmitters can be approached from any direction for faster, more accurate locates thanks to several, multi-directional antennas built into the underground pipe locator capturing the complete signal field.
