Multipurpose compact profiler GEOVIZER implements the method of induction multi-frequency mapping and enables to resolve the problem of fast and contactless surveying of the Earth. As a result of corresponding studies, it becomes possible to obtain spatial distribution of the level of secondary signal from the medium to a up to 3 m depth. The signal level allows for the evaluation of VES. Local high-contrast variations in the medium (metal objects, cavities, waterings with highly mineralized solution) are particularly trackable. More conductive objects (tunnels, bunkers with wet walls, pipes, etc.) in less conductive ground are also a good target for GEOVIZER.

GEOVIZER allows profiling on any set of 3 fixed frequencies in the range of 12.5 - 111 kHz, including with automatic referencing of the measurement point to global coordinates. The overall dimensions of the device (750 x 650 x 340 mm), weight (4.5 kg) and ease of operation (through smartphone with OS Android) - all these things significantly facilitate the process of data acquisition, as well as increase the spatial resolution of the survey.

GEOVIZER preliminary measurement results are visualized in real time on the smartphone screen. Dedicated app allows its users to build a quasi-3D image of signal distribution. The connection with the device is achieved via Bluetooth protocol.
