Benefits

Ready for Geophone Spread Cables

• GeoDAQ 5-24 is compatible with 61-pin spread cables and geophones, making it easy to deploy for conventional near-surface seismic crews.

Use One System for Multiple Survey Types

• The system can be used for refraction, reflection, passive monitoring, downhole acquisition, automated event detection, and stand-alone seismic recording.

Support Small Fast Crews

• Compact size, hammer switch triggering, and mesh Wi-Fi support make the GeoDAQ 5-24 useful for small, lightweight field crews.

Expand Into Larger Systems

• Multiple GeoDAQ units can be connected together through Ethernet and Wi-Fi for larger high-channel-count systems.

Improve Data Quality

• High dynamic range, low noise, wide bandwidth, and 24-bit acquisition help capture clean seismic data in demanding field conditions.

Simplify Field QC

• Built-in instrument and sensor tests allow crews to verify both the seismograph and the geophone spread before and during acquisition.

Support Remote Monitoring

• Continuous recording, cellular data support, and LTA/STA event detection make GeoDAQ 5-24 suitable for remote monitoring applications.
