Abstract
Systems for locating hidden utilities including a portable locator and associated portable transmitter are disclosed. The portable locator may include a magnetic field measurement module for determining a current signal in the hidden utility based on a received magnetic field, and a receiver module for receiving data from the portable transmitter. The portable transmitter may include a data transmitter module for wirelessly sending information associated with a current signal provided to the hidden utility to the portable receiver module. The portable receiver may be configured to measure a relative change in magnetic field angles, and determine an amount of cross coupling to adjacent utilities based at least in part on the measured magnetic field angles.
