depths. To avoid interference, the paired instruments of the EM38-DD and the EM38-MK2
work at different frequencies (Geonics Ltd., personal communications).
CM-138 (Gf Instruments, Czech Republic)
•
: The CM-138 is an EMI instrument and works
at one depth at a time. According to the operation manual, it has very similar parameters
as the EM38 (1 m coil spacing, 14.406 kHz).
