The "SGM-Iceberg-Probe" is a tactile search device constructed for the exploration of subterranean icebergs located beneath ice-skating rinks and other such hidden worlds. With the SGM-Probe (Subglacialis Montometer) subterranean life-forms and ecosystems can now be studied directly in their natural environment. The probe-line disappears into seemingly endless depths and functions as a sensitive interface between the two worlds. By combining sophisticated hard and software technology, this ground-breaking locator-system facilitates the comfortable research of subterranean icebergs and search-activity through the strata below. Information about the deep layers and their life forms will be made visible on the monitor located at the edge of the borehole and will be also be transmitted audibly via earphones.
