Sigma System Overview

The Sigma™ Advantage

Sigma™ is the sum of all cableless acquisition experience to date – the world’s first new generation cableless recorder. It is not only a multi-mode stand alone recorder, but it also works side-by-side with existing cabled hardware. Sigma™ is fully integrated with all Seismic Source Co. products and can outperform all rivals. Sigma™ will also work with any source, including the latest simultaneous vibroseis techniques such as slip sweep managing up to 256 groups, on any terrain, in shallow water and TZ. Sigma™ offers multiple data acquisition and retrieval modes integrated with well-proven, user friendly software. No other product provides this total solution with such comprehensive flexibility.
