EM61-MK2
The EM61 is a high sensitivity, high resolution, time domain metal detector suitable for the detection of both ferrous and and non-ferrous metal. Typical target response is a single, sharply defined peak, facilitating quick and accurate determination of location. Achievable depth of detection will depend on several target characteristics with the surface and orientation of the target and depends of the importance. A single 200L (55gal.) drum can be detected at 3m depths.

Acquisition
EM Sensors
1. Main: Air-cored coil, 1 x 0.5 m in size, coincident with EM source
2. Focusing: Air-cored coil, 1 x 0.5 m in size, 30 cm above main coil

Measured Quantities
Four time gates of secondary response in mV
Data from mutiple time gates – three or four, user-selectable – are recorded to provide a description of the response decay rate, supporting both the characterization and limited discrimation of targets. Data collection is supported by the DAS70-AR Data Acquisition System.
