Minelab metal mine detectors can be found in service in more than 55 countries around the world. Ideal for use in both military and humanitarian demining operations, Minelab detectors continue to be purchased by NGOs, commercial demining companies, the United Nations and individual nation state militaries.

With the introduction of the minimum metal mine (plastic mine), a vital
capability of a mine detector is to be able to detect very small amounts of metal.
Although the physics of metal detection does not vary greatly between detectors, difficulty is often encountered when mines are laid in mineralised soils. In this instance the conductivity of the soil can produce false alarms and mask the presence of a mine.


With its patented Multi Period Sensing (MPS) technology, Minelab detectors maintain maximum sensitivity regardless of the soil type.

· The sensitivity of a detector can also be affected by moisture on the surface of the search head (coil). In many cases, once a coil is wet or is used in shallow water, its sensitivity dramatically reduces. Minelab detectors use an enclosed waterproof coil that suffers no degradation in sensitivity when wet.  
The sensitivity of a detector can also be adversely affected due to the close proximity of overhead power lines (110/220/240 V 50/60 Hz). To eliminate this problem, Minelab detectors incorporate a “Noise Cancel” function in the electronics.

When Noise Cancel is initiated, the electronics automatically scans the surrounding environment searching over 4,000 iterations of frequency until the source of interference is detected. Once completed, the detector will select an alternative operating frequency to reduce or eliminate the original interference.



· Minelab metal mine detectors use mono-loop coils instead of the conventional Double D coil or concentric transmit and receive coils. The effect of this is to create the same level of sensitivity across the entire surface area of the coil. In contrast, many conventional detectors produce a “cone of detection” meaning that the area covered at the surface is not the same as covered at depth.

· Another advantage of the mono-loop coil is the “edge-to-edge detection” that permits easy pin pointing of targets. Also, against obstacles such as fences, the edge to- edge capability ensures a target will not be missed at depth.

· Another safety feature is obtained from the design of the battery pack. As the batteries begin to lose voltage, circuitry in the battery pack maintains the supplied voltage to the electronics at a constant level. This ensures maximum sensitivity is maintained. When battery voltage is reduced to such an extent that this can no longer be achieved, the operator is immediately notified via “battery low” flashing lightsand/or audio warning tone. At this point, the batteries must be replaced.

· Unlike many detectors, Minelab detectors provides a varied tone depending on the conductivity of the metal being detected. With correct training and experience it is possible for a deminer to learn more about a potential target. Additionally, the varied tonal response provides an additional safety feature in that it improves an operator’s ability to distinguish between multiple targets.
