Recent work by the Society has included development work with The Council for Independent Archaeology on the TR/CIA Geophysical Pseudo-section equipment which gives an electronic section of what is under the surface of the ground. Pseudo-sections are widely used in geology but the equipment and software has previously proved too expensive and cumbersome for archaeology. The TR/CIA equipment, designed to be used in conjunction with the TR/CIA resistance meter, overcomes these problems and has now been released for sale at a very reasonable cost.

Our small excavation carried out on a collapsed culvert in Wrest Park several years ago proved ideal for the test as it provided a known accurately drawn section which could be compared with a pseudo section taken across an undisturbed part of the culvert.

The above right photograph of the collapsed culvert and the section drawing published several years ago can be compared with the pseudo-section below produced recently

The Society owns a complete set of equipment and is using it to explore the possible site of the demolished Maulden Manor in Maulden Church Field and the site of Ampthill Castle near the Katherine’s Cross in Ampthill Park
