GCL-3

PRODUCT DETAILS

The GCL-3 is a self-contained, three-component, autonomous land wireless seismic data acquisition solution. Three internal geophones, battery, charger, 24-bit digitizer, GPS receiver, and GLONASS receiver are enclosed in its sealed case. A built-in test signal generator and up to 64 GB of non-volatile, solid-state data storage allow for quality and reliable data. Faster and more efficient operations can be achieved with the use of the GCL-3 by eliminating the process of engaging connectors for power and data transfer.
