The survey was undertaken using four Sensys FGM650/10 sensors mounted at 1m intervals (1m traverse interval) onto a rigid frame. The system was programmed to take readings at a frequency of 100Hz (allowing for a 1-2cm 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 Leica GS18 Real Time Kinetic (RTK) differential Global Positioning System (dGPS) outputting in NMEA mode to ensure a high positional accuracy for each data point. MonMX (Sensys Ltd) software was used to collect and export the data. Anomaly GeoSurvey v1.12.3 (Lichenstone Geoscience) and QGIS v.3.28.5 software was used to process and present the data respectively. The survey has identified a narrow range of anomalies that are interpreted as predominantly deriving from agricultural causes, identifying patterns of field drains, ridge and furrow cultivation and modern ploughing trends. The traces of ridge and furrow cultivation recorded by the survey share an alignment with the direction of ploughing recorded on the Warwickshire Historic Environment Record and appear constrained to the south-west corner of the survey area. The only other responses of note are two very high magnitude discrete anomalies, likely of anthropogenic origin, identified in the north-east corner of the survey area. Based on the survey results, the archaeological potential of the site is assessed as low.
