The RIDGID SeekTech 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 SeeSnake 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. SeekTech 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. The RIDGID SeekTech ST-510 includes the 10-Watt line transmitter to energize metallic lines for tracing, carry handle and extendable strap for sweeps, ground spike and 2 ft. to 25 ft. of coiled lead with heavy-duty clamps. The SeekTech ST-510 locator uses 3-connection methods: Direct Connection, Induction Method with SeekTech Inductive Signal Clamp 20973 (Sold Separately), surface induction (align lines on the unit with the pipe in the ground). Buttons, LCD display, LED indicator lights and audio feedback show impedance, resistance and wattage output, speed operation and confirms a good circuit before beginning a trace. Ideal for a pipeline, water supply, cast iron or large diameter hydrants and services.
