GCL Connectorless Autonomous Data Recorder
The GCL is a self-contained, autonomous data recorder. An internal geophone, battery, charger, 24-bit digitizer, GPS and GLONASS receiver are enclosed in its sealed case. A built-in test signal generator and up to 32 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 by eliminating the process of engaging connectors for power and data transfer.
