Multi Period Sensing (MPS) technology
MPS is designed to increase the depth and sensitivity of detection
The Multi Period Sensing (MPS) technology from Minelab is an advanced feature found in some of their metal detectors, especially those designed to find gold in difficult conditions. MPS is designed to increase the depth and sensitivity of detection without compromising discriminating ability, which is essential for effective searching in highly mineralized soils, such as those often found in gold-bearing areas.
Key aspects of Multi Period Sensing (MPS) technology:
-
Pulse Induction Technology:
- MPS is based on pulse induction (PI), a method where the detector emits strong and short magnetic pulses into the ground. These pulses induce a response from metallic objects, which then reflect these pulses back to the detector.
-
Multiple pulse timing:
- Unlike traditional PI systems that emit pulses at a uniform time interval, MPS uses different pulse lengths and timings during a single search cycle. This allows the detector to capture more information from a single target, improving detection capabilities at greater depth.
-
Signal Analysis:
- The detector analyzes the response back from different sizes, shapes, and types of metals at different time intervals. This makes it possible to better identify targets underground and distinguish them from mineral interference.
-
Improved sensitivity and depth:
- The MPS increases sensitivity to small, fine gold pieces while maintaining high efficiency in detecting larger objects at greater depths. This is particularly useful in areas where metal objects are buried deep beneath a layer of mineral-rich soil.
-
Discrimination capabilities:
- Although the MPS is powerful at detecting all types of metals, it also provides options for settings that allow users to discriminate against certain unwanted metals or ferrous waste, increasing the efficiency of the search.
MPS technology is important for prospectors operating in challenging environments where maximumtive sensitivity and depth to locate targets that might otherwise be missed using traditional detectors.
