General Information

Experience a significant boost in efficiency with the latest generation of the worldwide tried and tested UPEX® 740 M large loop. This flexible detection system of 1-2 m2 facilitates speedy surface surveying with a high level of depth penetration. To adapt to the local searching conditions, this new device is equipped with 3 search sensitivity levels LOW / MEDIUM / HIGH. An MK 82 could be detected at level MEDIUM at a depth of approximately 3 m.

The large loop delivers a wide detection range for mediumsized and large metal objects and can block out interference caused by strands of wire, nails, and low-volume scrap metal. This reduces the need for unnecessary excavation and speeds up the progress of work.


  • 3 sensitivity levels

  • 10 sampling delay levels

  • Analogue output

  • Reduced in-motion noise

  • Visual / acoustic signal

  • Simple operation, easy to manoeuvre

  • No equipment on main body

  • Extendable UXO detector

  • Good resolution capacity

  • Can be dismantled for transport

Operating Principle

Search system MF-3 is based on the EBINGER pulse induction system UPEX® 740 M, which can be described as an electromagnetic echo procedure. Via its search head, the PI detector emits magnetic pulses with a specific repetition frequency that induces eddy currents in search objects. An electromagnetic reaction is created, which is then picked up in the pulse pauses and electronically indicated on the display.

Support via EPAS® / EPAD®

UPEX 740® MF-3 is equipped with an analogue output for data recording with the EBINGER EPAD® data logger. This device records the values measured during the survey for later processing, analysis and conversion into digital anomaly maps. The raw data recordings / mappings are tamper-proof, making them ideal for QA & QC and documentation. This version conforms to the requirements of GIS systems (Geo-Information Systems) and supports IMSMA (Information Management System of Mine Action).

Optional geo-referencing allows for a longer time delay between detection work, interpretation and object recovery. In conventional analogue detection, the object had to be excavated directly after surveying in order to minimise the loss of coordinates.

The option of geo-referencing enables an interposed assessment of the data through, for example, high values for optimised clearing processes. This means that target lists facilitate efficient planning of clearance activities.

UPEX 740® MF-3 thus offers visual / acoustic search as a purely digital recording or a combination of the two.
