A solid-state, magnetically immune reference gyro that profiles borehole trajectory directly from the drill string, delivering fast, continuous surveys with an intuitive interface operators can use from day one.
Undetected deviation quietly inflates exploration costs, compromises core orientation, and weakens geological models while introducing safety and environmental risks.
Without a reliable, verified trajectory, every misaligned meter adds uncertainty, delays investment decisions, and undermines critical structural studies, especially where magnetic interference skews results.
GyroLogic™ Evo delivers continuous, accurate borehole profiles straight from the drill string, no rod removal required, bringing true gyroscopic navigation to mineral exploration.
Its magnetic immunity ensures dependable results in complex formations, while the driller-friendly interface enables confident operation from day one. With instant results, teams accelerate drilling, maintain QA/QC, and make faster, better-informed decisions.
Capture a complete trajectory in one run. GyroLogic™ Evo records borehole direction continuously, logging dozens of data points per second for maximum accuracy and confident QA/QC.
Solid-state gyroscopic technology is unaffected by magnetic interference, delivering dependable azimuth and dip in complex geology where magnetic tools struggle.
Simple, guided workflow lets crews perform directional surveys from day one, no specialist required. Faster onboarding, fewer user-dependent errors.
Compact, ergonomic one-piece design enables fast field deployment. Built to withstand harsh conditions without sacrificing precision.
Streamlined interface simplifies data capture and automates QA/QC report export, standardizing procedures across shifts and sites.
Uploads survey records directly to SPT SmartCloud™ for centralized custody, version history, and team collaboration, anytime, anywhere.
