With the objective to reduce cost while both maintaining the core performance characteristics of the more advanced PROTEM systems and adding several new performance-enhancing features, the new G-TEM system represents exceptional value in time domain electromagnetic (TDEM) instrumentation for both academic and commercial applications alike.

Designed as a complete system for exploration of the geologic near-surface, the modular G-TEM components are also compatible with all PROTEM system components, in cable reference mode only, supporting exploration to greater depths and a wider range of applications.

The integration of a Panasonic Toughbook computer as the system controller has provided the opportunity to introduce several new operating features, including:

• User-programmable receiver gate positions

• Single, multiple or continuous records during each measurement cycle; continuous recording facilitates mobile data collection

• Standard and smart integration (stacking) for low-noise data acquisition

• Multiple data presentation formats, including profile and colour pseudo-section

• Optional data inversion software providing in-field forward and inverse modelling capabilities

• Fast Fourier transform (FFT) function enabling characterization of data noise

• 320 GB data storage on internal hard drive; memory stick connectivity for data redundancy

• GPS compatibility, supporting GPS-assisted transmitter loop layout and graphical display of loop layout and receiver position; optional integrated GPS antenna

• Modular design that allows receiver/transmitter sections to be operated either as a single console, or two individual components to accommodate layout requirements
