Ervin Kraemer has spent more than 16 year working with the seismoelectric system originally developed in the UK. From early on Ervin has been involved in the improvement of both the system and operation protocols. In late 2011, Ervin began a multi-year journey in the complete redesign of the original system which included modernizing the circuitry, adding firmware controls and completely redesigning the user interface. This work culminated in the GF6 and later the PL14 Seismoelectric exploration systems.
