RIDGID
The SeekTech SR-24 is a locating receiver that creates maps of underground utilities. The unit uses Bluetooth® communications to transmit locating data to a third-party, survey-grade GPS or a mobile device. The unit can detect any active frequency from 10 Hertz to 35 Kilohertz. The device's omnidirectional antennas capture the complete signal field to locate a line and follow its path. The free RIDGIDtrax app provides basic utility mapping on a mobile device.
