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 survey has not identified any anomalies of definite archaeological origin. The results of the survey are limited to two faint linear trend anomalies likely agricultural in origin. It remains unclear whether these anomalies which share a north-west/south-east alignment are faint traces of ridge and furrow identified in LiDAR data. Elsewhere magnetic disturbance is widespread and present at the field boundaries. A dipolar anomaly and spread of magnetic disturbance in the north-west corner of the Site identifies an extant borehole. The findings from the survey at this Site are consistent with the known limited archaeological potential of the area covered by LS-WSI Group 007 which does not lie within a Recognized Archaeological Zone (RAZ).
