The EM61-MK2, an enhanced version of the patented EM61, is a time domain metal detector which detects both ferrous and non-ferrous objects with excellent spatial resolution. Target response is a single, sharply defined peak, facilitating quick and accurate target location. A single 200 liter (55 gal.) drum can be detected at depths greater than three meters; modification for increased power, to increase both the sensitivity to smaller targets and depth of detection, for all targets, is available. Data from multiple time gates - three or four, user-selectable - are recorded to provide a more complete measurement of the response decay rate for improved target characterization (and discrimination). Early time gates increase the maximum depth of detection for all targets; a mid-range time gate, at the same position as the original EM61, offers comparison with, and continuation of original EM61 data sets.
Data acquisition is supported by the Allegro CX field computer. Important features include real-time graphic display of data for review and quality control; high capacity (256M) data storage for extended survey time; increased rate of data collection; and additional input connections for simultaneous collection of EM and GPS data.
The system is immediately GPS compatible; a fully integrated Trimble AG114 - with no requirement for a separate GPS receiver console - is available as an option.
The system can be pulled as a trailer, in single or multiple unit configurations, or carried by an operator with a belt harness.
