Geonics EM-61 MK2 A metal locator

The newest version of the Geonics EM61, the MKIIA, eliminates the need to put on a backpack. New brackets on the coils and carry-handle support the battery, electronics and data logger. In addition, the newest rev coils are encased in a plasticized medium that is much more resistant to moisture.

Suggested Optional Accessories: For automatic integration with GPS, we suggest the Trackmaker 61 software operating with the Trimble AG114 GPS unit. Description The EM61-MK2A is a high sensitivity, high resolution, time domain metal detector suitable for the detection of both ferrous 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 area and orientation of the target of particular importance. A single 200 litre (55 gal.) drum can be detected at depths greater than three metres. In comparison with the previous-standard EM61-MK2, the EM61-MK2A provides the same feature and performance specifications.

Differences between the two models are ergonomic: because the A-model does not include a backpack for system components, the electronics console is mounted on the U-handle, and the battery is positioned in the centre of the coils. Data from multiple time gates -- three or four, user-selectable -- are recorded to provide a description of the response decay rate, supporting both the characterization and limited discrimination of targets. Data collection is supported by the DAS70-AR Data Acquisition System.
