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.

This technique 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. We deploy a multiplex probe system, which can easily be configured to collect data at different probe separations to provide different depths of investigation according to the requirements of your project.

Magnetometry

Measures the ambient magnetic field strength. Effective for detecting features with magnetic contrast from the surrounding soil, including burnt features, pits and ditches.

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.

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.
