The survey was undertaken using four Bartington Grad601 sensors mounted at 1m intervals (1m traverse interval) onto a rigid carrying frame. The system was programmed to take readings at a frequency of 10Hz (allowing for a 10-15cm sample interval) on roaming traverses (swaths) 4m apart. These readings were stored on an external weatherproof laptop and later downloaded for processing and interpretation. The system was linked to a Trimble R8s Real Time Kinetic (RTK) differential Global Positioning System (dGPS) outputting in NMEA mode to ensure a high positional accuracy for each data point, in accordance with EAC guidelines (EAC 2016). The results of the survey are limited to areas of magnetic disturbance at the field boundaries and several very low magnitude discreet anomalies likely natural in origin. No anomalies were recorded consistent with ridge and furrow identified in LiDAR/remote sensing data and the findings from the survey are consistent with the known limited archaeological potential of the area covered by LS-WSI Group 007 which site does not lie within a Recognized Archaeological Zone (RAZ).
