Borehole position and core orientation data in one run.

One tool – One run – Two services



Multi-diameter digital core orientation device. Discover the next generation.

One Tool, two solutions

The GyroCore™ can accurately orient core and survey at the same time, in all inclinations, even at vertical.

This Gyro While Drilling (GWD) saves time for Geologists doing two operations in one run.

Core Orientation, even at vertical

The digital Core Orientation mode helps to determine planning for future drilling, and in the design of the mine itself.

Increases discovery opportunities. Reduces developmental and future costs, by determining the plan forward.

Borehole Position, True North Seeking

Depicts the position of the borehole in a 3-Dimensional Space trough an accurate survey.

Provides the Geologists with direction, inclination and North Easting coordinates or bottom hole location.
