Each module can either inject current or receive the signal, which is then transmitted digitally to the central unit. The digital transmission prevents cross-talk and signal degradation along the cables, ensuring high-quality data even with minimal injected currents.<\/p>\n<p>ELECTRA can inject any type of current into the ground at various frequencies. Alternating current measurements are faster and more precise since they do not require signal stabilization time and minimize induced polarization effects on the electrodes.<\/p>\n<p><strong>What does it do?<\/strong><br \/>\nWater exploration, cavity detection, mineral prospecting, environmental issues, foundation inspections, archaeological research, or the assessment of wall structures and coatings are just some of the fields where large- and small-scale electrical surveys can be essential.<\/p>\n<p>ELECTRA allows for subsurface and anthropogenic artifact investigations with an exceptional ease of use.<\/p>\n<p>With ELECTRA, traditional methods such as Wenner, Schlumberger, dipole-dipole, pole-dipole, spontaneous potentials, induced polarization (and others) can be performed fully automatically.<\/p>\n<p><strong>ELECTRA is also available in the MATRIX version, designed for small-scale, high-resolution applications, even in non-geological
