Renishaw's industry standard Cabled Boretrak® utilises a solid state magnetic compass and menu technology to enable users to quickly and safely survey blast hole geometry for blast design and audit purposes.
The compass allows the use of the Boretrak in non-magnetic areas.

Renishaw has designed the Cabled Boretrak® as a means of auditing the results of drilling activity quickly and accurately. Incorrect setting of drill angles, borehole wander and drilling to incorrect depths, results in service problems, particularly in the mining, quarrying and construction industries.
The system features a rugged probe containing a dual axis tilt sensor and digital compass that calculates the borehole deviation from the collar position at fixed intervals. Data is transmitted to the surface via the heavy duty cable and recorded in the Renishaw CDU logger. The CDU can be handheld or attached to the Renishaw lightweight tripod for ease of use.
The Boretrak® system is also supplied with a weighted extension piece that can be filled with lead shot or sand, to ballast the system for use in deep or flooded holes.
Renishaw's Boretrak® 3D software is used to process the data and produce a hard copy of the results. Holes can be displayed individually, or in any combination to determine hole separations. The data can also be integrated into 3rd party software systems, including Renishaw's Face 3D software.
