Subject of the new German metal detector DRS GROUND EXPER received a lot of feedback . Therefore, readers of the blog will continue to introduce little-known models of metal detectors.
One of these detectors are unfamiliar to most hunters , a metal detector GEOScan-M45, which produces a Russian company ” Fragma “.
According to the manufacturer, Metal detector GEOScan-M45 has unique abilities , and he is able to reflect the shape of the found object and the type of metal detectors that helps to more accurately decide on the need to extract from the soil of the detected target .
Let’s see what is behind these loud statement .
GEOScan-M45 refer to the class of eddy current metal detectors. Principle of operation – the “transfer – acceptance ” ( induction balance).
GEOScan has 4 modes of display signal from the sensor , two for the dynamic mode , two for static mode .
The first display mode is a graphic visualization of the contour shape of the metal detectors object from the measured signal by mapping the type of metal detectors. type is determined by the polarity of the displayed contour relative to the center line .
1 – Iron Nail (magnetic metal)
3 – Gold chain (non-magnetic metal)
2 – Gold earring covered with a nail (a mixture of metals)
The second – string display mode indicator .
The third mode is a display form of a graphical visualization of the metal detectors object from the measured signal without displaying the type of metal detector used full scale . In the third mode shows the depth of detected metal object in centimeters (manufacturer assures that the detector GEOScan-M45 measures the depth of the metal detector object with an accuracy of up to 95 %).
In addition to this new metal detector GEOScan-M45 is equipped with a sound indication polytonality . Each type of metal detector has its own audio tone . The tone may increase or decrease depending on the size of the detected metal object.
To the unit produced a variety of search coil diameter of 10 cm, 40 cm All coils are waterproof. In the standard GEOScan-M45 comes with a coil diameter of 26 cm According to the information given on the site, this reel is suitable for coin at a depth of 40 cm or larger scrap metal to a depth of 3 meters.
Also for this model metal detector manufacturer offers to buy the deep probe diameter of 80 cm using a coil can try to detect metal objects at depths of up to 8 meters!
