Illuminating the Deep with Natural Currents

About Master

MASTER (Magnetotelluric Acquisition Systems for Terrestrial Earth Research) is a cutting-edge system that measures Earth’s faint electromagnetic fields to precisely map underground electrical conductivity.

Why choose MASTER?

Go Deeper: MT can probe from tens of meters to hundreds of kilometres in depth, making it one of the few geophysical methods effective for both shallow and deep crustal/mantle studies.
Natural and Non-Invasive Method: Uses Earth’s own signals, so it’s less intrusive and easier to set up.
Wide Range of Applications: Mineral exploration, geothermal resource assessment, groundwater studies, and tectonic/structural investigations. Provides critical insights into crustal and mantle electrical conductivity structures.
Cost-Effective at Large Scales: Since it doesn’t require expensive artificial EM sources, MT is cost-effective for regional surveys.
Built Tough: Designed for real-world research conditions.
