GEM-2A
The GEM-2A is our standard airborne
instrument. It is a programmable, broadband EM sensor for Geologic investigation, ground water surveys, and mineral
exploration. The system utilizes a single set of transmitter-receiver coils for all frequencies,
rendering an advanced HEM system with high sensitivity, light weight, and minimal drift. The frequencies
are selectable and it also includes power line monitoring.
The GEM-2A has both horizontal coplanar and coaxial coil sets The tow cable provides DC power
and digital communications.
The software also converts the data to apparent conductivity at each frequency and to apparent
susceptibility at the lowest frequency.
