StructMaster™ Portable Digital oriented core logging.

Minimizes user dependency through fast automated image-based logging for maximum traceability beyond the core shack. StructMaster™ is fully integrated in a single handheld device.

Human Error

The Weak Link in Structural Mapping

Structural logging tools today don’t allow verification. You capture strike and dip values and move on. If something’s off, whether due to poor lighting, bad orientation, or simple fatigue, there’s no easy way to catch it later. 

No Way Back

The Irreversibility of Today’s Logs

Geologists are forced to make high-stakes decisions based on unvalidated data.

With no visual context and no audit trail, structural logs become a black box. And when these logs feed into 3D models and resource estimates, even small misreads can cost big.

Logging Reinvented

Verify, Audit, Repeat—Anywhere

StructMaster™ closes the verification gap. Each structural measurement is stored with an image of the feature itself, allowing full traceability. Angles can be recalculated at anytime and because it runs on any Android device, it’s the most portable, scalable solution on the market.

Log, verify, and revisit—StructMaster brings transparency and confidence back to structural geology. 

What Makes StructMaster™ Unique? 

The First Portable Structural Logging Device With Image-Based Auditability 

Every measurement is backed by an image, ensuring full traceability and error correction anytime, anywhere. 

Minimizes User Dependency for Improved Accuracy 

Unlike other core orientation tools, StructMaster™ does not rely on user skill for precision, drastically reducing human error. 

Recalculate Alpha & Beta Angles Anytime 

No need to re-measure—recalculate structural angles directly from captured images beyond the core shack, ensuring accurate, reliable data.

Instant, High-Precision Digital Core Logging 

Log geological structures angle in seconds, not minutes with the automated process.

Seamless Data Synchronization with SmartCloud™ 

Share, analyze, and collaborate on structural data in real time. 

Ultra-Portable, No Extra Equipment Needed 

No need to re-measure—recalculate structural angles directly from captured images beyond the core shack, ensuring accurate, reliable data.

Gamma Angle Estimation, Built Into Your Workflow

StructMaster™ already helps users calculate Alpha and Beta angles within the oriented core logging workflow. Now, it also supports Gamma angle estimation directly inside the app. Users select the structure to register, manually or with the automatic assistant, then define the reference lineament for that entry.

StructMaster™ calculates the Gamma angle and uses it to automatically derive Trend and Plunge, displaying the results on the stereonet. This helps streamline structural logging, reduce manual interpretation steps, and keep key orientation data connected inside a single digital workflow.

How StructMaster™ Works 

1

Capture a high-resolution image of the structure to log in the core. 

2

The device instantly calculates Alpha & Beta angles with precision logging software. 

3

Data is stored securely, auditable anytime via SmartCloud™ integration. 

4

If needed, angles can be recalculated later without re-measuring anywhere anytime. 

Full Traceability and Integrated Geological Modeling with SPT SmartCloud™

StructMaster™ automatically connects to SPT SmartCloud™, linking each structural measurement with verifiable images projected in stereonet. This integration ensures full traceability, allowing users to access, validate, and correct structures from anywhere, backed by solid visual evidence.

The integration of drill alignment, borehole trajectory, core orientation, and structural logging data in a single digital environment enables review, correction, and consolidation of all information to build a precise and consistent geological model.
