The FEREX is a vertical gradient fluxgate magnetometer that measures the deformation of the earth's magnetic field evoked by ferromagnetic objects. Magnetometers are suitable for

the detection of ferromagnetic metals like iron, steel or nickel. Normally the detection Depth of magnetometers is larger compared to active EMI detectors but it varies and depends on

the object's mass and its magnetic properties.

The FEREX 4.034 can be used either in direct meter mode or in data recording mode. Four channels for data recording allow the FEREX 4.034 to be expanded into a multi probe holder system for large area survey. The device offers the possibility to connect alternative sensors and GPS systems via a serial interface. These allow precise navigation and geo-referencing of the recorded data..
