G-TEM 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.

The TEM57-MK2 Transmitter is the upgraded version of the TEM57, and combined with the PROTEM receiver are the principal components of the PROTEM 57-MK2 system. The design and performance of the TEM57-MK2, with increased power of 1,500 W from an internal power supply, makes it a highly portable, powerful mid-range time domain transmitter. The internal power supply has variable voltage range from 18 to 60 V so that it can be precisely matched to the transmitter loop for optimum performance. An external battery supply increases performance to 3,800 W and 160 V.
