Description

Second-hand EM61-MK2A : metal detector

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. We recently decided to sell a second-hand EM61-MK2A to renew our park.

Working principle

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 meters.

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 center 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.

The system can be pushed or pulled as a trailer, by person or vehicle, as either a single unit or an array of multiple units; for multiple unit configurations, options are available to customize component specifications and layout. As may be required, with the addition of a backpack and associated cable set, the system can be carried by a single person with a belt harness.

Second-hand EM61-MK2A

We propose second-hand EM61-MK2A, sold with an Archer data logger. This equipment was made in 2010 and it is in good shape. Please do not hesitate to contact us for any further information you may require.
