Perfect DC resolution
Automated stacking for data quality enhancement
During the data measurement process, GD-10 automatically analyzes signal strength and data quality to determine whether long measurement period and stacking mode should be activated. For sites with strong signal and good data quality, measurement system continuously sweep and scans in high efficiency mode until bad data quality is detected, in which long measurement period or stacking mode would be elaborated to enhance data quality to the maximum extent. Clients can also set stacking amount according to any survey points, survey layers or individual tasks.
