IT WORKS .. Only for magnetic materials – Metal Detector Review

Pro : - user adjustable alarm threshold that some of its competition don't have. .. Benefit - made it acutely sensitive to small difference in field discontinuity around steel and magnetic materials, thereby its detection capability and penetration. Application : - pre-detection routine : require a new threshold settings for acute result from : - object to object, - phone<>object relative orientations, as well as - phone's geo-orientation. Next release nice to have : - calibration button .. to register an ambient field average value when phone's geo-orientation is prefixed and ready to go detect in that orientation. Then the software will set detection threshold at (K*average); where K is a threshold factor and is also user adjustable, default is 1.40.
