Achieve true directional precision with the world’s most advanced solid-state gyro survey tool, powered by SPT’s Navibore™ Technology and distributed exclusively in Ghana by AGS.
In mining and geotechnical operations, borehole deviation is more than a technical issue. It’s a costly obstacle to accurate decision-making.
When holes drift off course, geological interpretations become unreliable, resource estimates lose precision, and project timelines extend unnecessarily.
Traditional magnetic or surface-referenced tools struggle in complex geological environments, producing inconsistent readings and incomplete data, leading to costly rework and uncertainty in your survey results.
The GyroMaster™ eliminates uncertainty by delivering true, magnetic-free borehole surveying with centimeter-level accuracy. Powered by SPT’s proprietary Navibore™ Technology, it records continuous data in real-time — even in the harshest mining environments.
Whether you’re drilling vertically, at an angle, or through magnetic formations, the GyroMaster™ ensures every reading is accurate, traceable, and repeatable.
The result? Reliable structural data, faster geological interpretation, and reduced operational costs.
Records data at every centimeter, delivering unmatched precision.
Operates flawlessly in both magnetic and non-magnetic environments.
Seamless data sync to SmartCloud™.
Works in all borehole types and geometries, including S-curves and deviated holes
Up to 20 hours of continuous operation. Withstands -35 °C to +70 °C and up to 10,000 psi
Automatically generates survey pdf reports which can be shared with stakeholders.
Simplified workflow reduces setup time and training needs.
