When using, security officials grip the handle with hand, press the power button with thumb then release. At this time, the instrument lights began flashing and the speaker also issued a very slight beep, which means that the instrument has been into operation. Staffs with handheld instrument after powered scan back and forth on the object surface, if there have metal items, the machine will sound. Kingdetector tips, after the inspection is completed, you should press the stop button, in order to avoid wasting battery power.
How to determine the size of the metal objects: physiology indicate that human hearing changes in volume is relatively slow (logarithmic), and changes in tone is more sensitive (linear), according to the above theory, we can judge the size of metal objects by tone.
Rest in Peace
