The detection process is specific to the chemistry of the explosive, and therefore is less susceptible to the types of false alarms experienced by metal detectors and ground-penetrating radars.
Metal detectors are simple, effective, and inexpensive remote sensing tools with real value to archaeologists.
This paper reports demining procedures involving metal detectors and concludes that a target depth indication, even if crude, would be a useful innovation.
The negative association between metal detectors and urban students’ sense of safety is 13% less than what it is for students attending suburban or rural schools.
The sensitivity of the system is practically preferable to that of metal detectors.

Compared with conventional hand-held detectors, much more sophisticated signal processing should be feasible, and it may be possible to reduce false alarm rates on metallic mines and nonmetallic mines with metal fuses.
The insight given by this paper into metal detectors, will allow those not familiar with such instruments, a better understanding of their potential and limitations.
from a preliminary analysis of even these simple cases explain a number of previous experimental observations, for example, the greater influence of magnetic properties than of electrical conductivity on the performance of metal detectors.
