Disclosed is a non-invasive long-range substance detection device stemmed from the principles of the Earth's field nuclear magnetic resonance (BPM/IR), by way of emitting powered excitation pulses of Larmor frequency (LF) calculated from the Earth's magnetic field (EMF) in the target-searching area and then measuring the corresponding resonance responses of the potential targets. The present invention provides a compact substance-detecting and target-locating device with characteristic features of non-invasive, non-destructive, and long-range detection for any substance, which can be potentially applied in mineral prospecting and exploration, environmental monitoring, archaeology and other relevant fields. The detection mechanism of the present invention can be briefly described as follows: by emitting powered AF electromagnetic pulses with target's LF in the search area, the specific magnetic nuclei of potential targets resided in the search area would absorb the electromagnetic energy carried by the AF electromagnetic pulses and thus generate 1 corresponding EFFHVIR responses that are manifested as distinct and detectable energy-absorbing power lines (EAPL) connecting the AF signal source and the potential targets; in the meantime, through probing and measuring the EAPL to determine directions and distances of the potential targets relative to the AF signal source, the targets can be eventually located remotely without tampering and disturbing the targets physically and chemically.
