GyroLogic™ Evo

GyroLogic™ Evo: Precision Surveying in Any Environment

GyroLogic™ Evo is an advanced solid-state gyroscopic survey tool engineered for accurate borehole navigation in magnetically disturbed environments. Unlike conventional tools that struggle with magnetic interference, GyroLogic™ Evo provides continuous, complete immunity to external magnetic fields, delivering reliable trajectory data even in casing or ore bodies that would compromise other instruments. Its compact, rugged one-piece design, machined from copper-beryllium, is small enough at 35 mm in diameter and light enough at 4.5 kg to enable easy handling and fast deployment.

Designed for operator simplicity, GyroLogic™ Evo allows drill crews to perform high-precision directional surveys from day one without needing external specialists. The tool operates inside the drill string without rod removal, significantly reducing non-productive time and increasing meters drilled per hour. Continuous surveying mode captures dozens of data points per second, ensuring extreme structural precision and enabling rapid, detailed borehole profiling.

GyroLogic™ Evo integrates seamlessly with SPT SmartCloud™, automatically uploading survey records organized by project and borehole. QA/QC reports can be generated with a single click and exported in popular formats such as PDF, Excel, CSV, LAS, and DXF. Powered by a rechargeable lithium-ion battery with 12 hours of active surveying, and paired with an IP68/IP69K-rated handheld device, GyroLogic™ Evo is built for the toughest conditions on any drilling site.
