The SR-24 is a precision utility locating instrument with GPS and Bluetooth® technology for easy integration with external data capture devices.

The SR-24’s omnidirectional antennas capture the complete signal field, making it easy to acquire the signal and trace its path. The receiver displays the utility's position and direction on the display, providing an intuitive locating experience. For added confidence, audio and visual warnings notify the operator if the shape of the signal field is being distorted so that appropriate action can be taken to avoid mismarking the utility’s position.

RIDGIDtrax enables basic underground utility mapping in real time. Connect an Android or iOS device wirelessly to a RIDGID SR-24 Utility Locator and RIDGIDtrax will display GPS position and depth of the target utility. A user can identify the type of utility (water, gas, electric, etc.) and display multiple utilities on the same map. A finished map can be saved and viewed inside the app or exported to a *.KMZ file for use with popular GIS programs such as Google Earth®.
