Geological and geotechnical survey, agriculture, archaeology, groundwater protection, environmental monitoring, raw material prospecting, metal object and network detection.

Large family of CMD electromagnetic conductivity meters is designed for survey depth ranges from 0.15 to 60 m. Used contactless method allows fast measurement of conductivity and inphase under all field conditions (including very dry and icy ground). Probes are equipped with 1, 3 or 6 receivers with excellent temperature stability. This way makes high resolution depth graded mapping as well as imaging of sections possible and useful for wide range of walking and moving applications.


CMD-MiniExplorer: three-depth probe
with depth ranges 0.5 / 0.25 m, 1.0 / 0.5 m, 1.8 / 0.9 m
for archaeology, agriculture and civil engineering, allowing immediate judgement of vertical conductivity gradient.

CMD-Explorer: three-depth probe
with depth ranges 2.2 / 1.1 m, 4.2 / 2.1 m, 6.7 / 3.3 m
for extra wide range of applications with evaluation of vertical and horizontal conductivity changes.

for archeology, agriculture and buried metal
object detection.

CMD-2: single-depth probe
with 3.0 / 1.5 m depth range
frequently used for assessment of corrosivity risk
at pipeline construction and for geologic judgement
of construction sites.
