Broad Sensor and Instrument Compatibility

Fully compatible with any transmitter system, several reciever sytems and most geophysical sensors, including industry-standard induction coils:

Zonge ANT-4/6
Phoenix MTC-185U
LEMI/KMS
Geometrics

iSense

The iSense is a compact, Hall sensor, current monitor designed for any controlled source survey with any transmitter system.

It measures transmitter current (80 mV/A) to enable precise full time-series recording with any gDAS-32.

Accurate full current waveforms are essential for post-processing most controlled source datasets, including Time-Domain IP, Complex Resistivity, and CSEM.

gDAS App

The gDAS32 offers an intuitive Android app for seamless interaction with the instrument and control of geophysical data acquisition.

Through Bluetooth or extended-range radios, users can easily manage settings, monitor real-time data, and initiate time series acquisitions.

gDASPro data processing software

Survey Management & Processing

gDASPro centralizes all survey data in a single SQLite database, handling configurations, source/sensor info, time series links, and results. It guides users from initial setup to final visualizations—sections, maps, and 3D plots—in industry-standard formats like EDI, AVG, DAT and AMIRA.

Flexible Workflow

Supports manual or batch linking of data to sources and sensors.
Enables editing and processing at station, line, or area level.
Output-ready for inversion software.
