The Centaur digital recorder is a portable seismic acquisition system that consists of a high-resolution 24-bit ADC, a precision GPS clock, and removable storage capabilities. The Centaur is available in both 3- or 6-channel versions, as well as with a high-gain option. Its ease of use simplifies high-performance seismic deployments in both remote and networked environments. 

The Centaur now has expandable memory and even lower power requirements. In fact, the 3-channel version requires less than 1 watt with telemetry. The on-board 8GB memory (standard on both 3- and 6-channel) is expandable up to 64GB by adding an internal SD card.
