I ASKED SOMEBODY TO DETECT MY PROJECT. WHEN WE WERE ABOUT 800 METERS FROM THE LOCATION, HE USED HIS MACHINE AND IT POINTED TO WHERE OUR PROJECT IS. WE WENT NEARER OF ABOUT 3 METERS AND AGAIN IT POINTED TO WHERE WE SUSPECTED THE OBJECT IS. THEN HE "BURNED" THE SIGNAL. AND HE DETECTED AGAIN AND THERE WAS NO MORE SIGNAL. DOES THIS MEAN THAT THERE IS NO OBJECT. ACCORDING TO THE OWNER IT WAS "FRQUENCY MODULAR DETECTION". PLEASE TELL ME MORE ABOUT IT AND HOW REALIBLE IS IT.
