This report details fieldwork on a suspected Roman fort in the grounds of Drumlanrig Castle. Geophysical survey was undertaken in the first instance using a 1.0 m separation fluxgate gradiometer system and the base plan of the fort was confirmed. Additionally a prototype wheeled square array was used to collect earth resistance values in order to investigate further the findings of the magnetic survey. The short report discusses some of the technical issues involved with the wheeled array and identifies technical improvements that have been implemented since the trial.
