BackSpecificationsEmploying the concept that a radio signal is absorbed (attenuated) as it propagates through the rock and soil mass. Its speed and rate of attenuation are functions of its frequency and the electrical conductivity of the rock and soil. By placing a transmitter of a radio signal at one point and a receiver at another its possible to measure the signal loss of the path between the two points. A radio frequency at a specific frequency travels faster and further through low conductivity media (limestone, coal, potash ) than through materials with high conductivity (shale, mudstone, clay, ore zones etc).
