The Ridgid SR-24 is a precision utility locating instrument with GPS and Bluetooth technology for easy integration with external data capture devices. Its 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, visual and audio warnings notify the user if the shape of the signal field is being distorted so that appropriate action can be taken to avoid mismarking the position of the utility.
