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). All suitable areas within the site were surveyed and no anomalies of archaeological or possible archaeological origin have been identified. This includes any which may relate to a potential burial mound and an area of cropmarks and geophysical anomalies to the south of Moor Hall approximately 650m to the south-east recorded in RAZ 28. There is also no evidence of anomalies which could relate to a series of Linear LiDAR/remote sensing features, possibly linked to ancient woodland at Wrinehill approximately 700m to the west. The findings of the survey are limited to a pattern of field drains in the southern field, areas of magnetic disturbance caused by track matting and boundary fences and occasional and discrete, low magnitude and dipolar 'spike' anomalies are of natural and modern causes respectively.
