A gradient sensing probe system, and method of using same, including a sensing segment which includes a plurality of sensors, a support structure, and an electrical interface having first and second faces. The system further includes a housing, a power source, and an electronics package including a controller and disposed within the housing. The sensing segment is configured to measure external gradients and to exchange data with the controller. The power source is connected energetically to provide power to the sensing segment and the electronics package, and is controlled by the controller.
