 (1) Canadian GEM produced integrated electromagnetic and magnetometer method instrument: GSM-19TV, the standard proton magnetometer GSM-19T or GSM-19W high-precision magnetometer + VLF power modules, which VLF astatic 3 - Coil sensor for receiving the launch pad three VLF VLF signal frequency range of 15KHz-30KHz, measuring the vertical component of the same phase and different phase of the total farm value percentage (%), the components include: ● placed in magnetometer console within the VLF electronic devices? ●? the VLF sensor Operating manual? this VLF is mainly used for the dip pattern 2. Canadian the Geonics company production of very low frequency VLF electromagnetic method (Independent), including: ● EM16 of VLF receiver (for dip mode)? ● EM16R? VLF resistivity instrument EM16 co-ordination (for resistivity model) ● EM16/16R EM16 and EM16R of integration? ● TX27? the VLF portable transmitter ● the EX700 TX27 power (350w generator, may be domestic purchase)? VLF VLF method works 
 VLF electromagnetic VLF dependent distribution in the world 11 launch pad VLF electromagnetic very low frequency electromagnetic signals. VLF electromagnetic signals projected onto the buried conductor material, and generate electromagnetic induction. VLF electromagnetic method instrument observing this sensor signal and recorded, to search for underground targets conductor. Underground conductor is vertical or steep dip of the ore body and mineralized zones, faults, dykes, broken band or the joints with and so on. In mineral exploration, VLF method is low cost, rapid method of exploration is mainly used for the detection of shallow buried, the steep dip of the ore body and the mineralized zone. Mainly used to detect groundwater-related vertical fracture and fracture zone in the groundwater exploration. 
 In order to get stronger sensor signal, the line of exploration should be perpendicular to the underground conductor trend, usually for a large area of ??the census stage. The VLF method is passive field source electromagnetic method can also be used to bring their own VLF transmitter. In this case, the distance between transmitter and receiver are generally 15-30km, to ensure that the emission of electromagnetic waves into plane waves, the VLF method can be used two observation modes: the dip pattern and resistivity models.
