The detailed magnetic survey was carried out using a SENSYS MAGNETO MX V3 6 channel cart-based system. The instrument has 6 fluxgate gradiometers (FGM650) spaced 0.5m apart with readings recorded at 20Hz which equates to a survey resolution of 0.5m by 0.15m. The survey aimed to determine the archaeological potential of a possible Roman site identified by fieldwalking. While the results indicate a response to a number of linear boundaries associated with a field system, there is no clear evidence for platforms or structural remains within the site. Widespread naturally formed anomalies appear to relate to a zone of unmapped clay-with-flints deposits on the higher ground. There is some evidence for flint extraction and a small number of anomalies with an uncertain origin, including a negative rectilinear anomaly and a small number of positive linear responses. A positive response along the southern edge of the site could relate to colluvium in the base of a dry valley, although an association with a former boundary earthwork is possible.
