The pictures indicate the 3-axis gradiometer (total field) below. Despite single-axis gradiometers performing capturing the field in a single direction, the 3-axis gradiometers, also called the total field, capture the field from 3 different angles and axes (x, y, and z-axis) six FLC-100 Stefan Mayer sensors or two 3-direction, professional Stefan Mayer sensors.
Comparing 3-axis gradiometer scanner (total field)
The total field systems are suitable for deeper explorations. Unlike the single-axis system, they are used for explorations aiming at bigger purposes. These systems have higher capabilities in eliminating particles and false purposes and bipolar recognition of ferromagnetic metals in each state that they are placed in the depth of the ground. Also, they are able to record two metals or two holes placed on each other.
