Electromagnetic Conductivity (EM)

Measures the ease of which current flow can be induced in material. Effective for detecting conductive features, such as geomorphology and subsurface landforms, ditches and earthworks.

Electromagnetic Conductivity (EM) measures the ease with which electrical current can be induced in a material.

Effective for conductive features, such as geomorphological features, ditches and earthworks. Our equipment can be configured as a wide array to locate geomorphological features at depth, or as a smaller array to detect finer and shallower features such as earthworks and ditches.

Our techniques

Learn more about the techniques that we use.

Earth Resistance (ER)

Measures the difficulty of passing an electric current through the ground. Effective for detecting features with different moisture content from the surrounding soil, such as foundation remains and ditches.

Magnetic Susceptibility

Measures the ease with which a material can be magnetised. Effective for detecting features with magnetic contrast from the surrounding soil, including burnt features, pits, ditches, and intra-site activity zones.

Aerial Reconnaissance

Incorporating aerial imaging during ‘walkover’ surveys extends the visual range of the surveyor, allowing reconnaissance to be carried out more safely and efficiently, with vastly more informative visual outputs.
