The EMD2 is an active, highly sensitive system for middle sized area surveys using the TDEM („Time Domain Electro-magnetics“) method in order to detect metals in the ground.
It is made for high precision electromagnetic cartographies of small and middle sized areas in order to support UXO and EOD teams, geophysicists or archaeological surveys. The EMD2 comes with three pairs of differential coils giving a higher resolution for optimized identification of single objects. Measurement data is being digitized and logged with the compact EMD2 electronics.
The rugged PDA with DGPS connection can be used in order to allow free navigation in field, straight display of survey lines and a geo-referencing of the data. It is also possible to use the system for data logging without a GPS. Data processing and interpretation will be done on a PC equipped with the SENSYS MAGNETO® software.
The whole system is lightweight designed and easily dismountable, but made for heavy duty use in the field.
