Geophex - Model GEM-2H -Built-in Data Logger

The GEM-2H has customer adjustable frequencies ranging from 30Hz to 96000Hz, up to 10 combined selectable frequencies, suitable for small, near surface targets as well as large, deep geologies. The Gem-2H has a higher dipole moment indicating stronger signal-to-noise ratio and sensitivity. Presence of high frequencies enables detection of non-conductive (void) targets as well which is ideal for detecting plastic pipelines, disturbed soil, subsurface oil contaminants, and forensic sites.
