Magnetic multi-purpose drill hole surveying system.


The Champ Discoverer electronic multishot is a magnetic drill hole surveying system purpose-built for the toughest conditions.

The hand-held ruggedised tablet communicates wirelessly with the Champ Discoverer probe through an infra-red data link. Simple to use, intuitive software manages singleshot, multishot or orientation surveys.

The 38mm Discoverer is a non-integrated system which has interchangeable sensor packs, battery packs and pressure barrels. By design, it will continue to perform in even the harshest conditions which along with its interchangeable components is well suited for remote locations, logistically difficult countries or areas and for projects where continuing operations is critical.

Two field changeable long life re-chargeable battery packs provide for redundancy and assures un-interrupted operations.

Upon download, quality control functions can be applied and data viewed in real-time on screen at the rig site or upload to Axis onTrack™ Survey Analysis Software, for  further features such as enhanced analysis, survey and 3D graphical views as well as report generation.

For rental customers, the Champ Discoverer is supplied with required running gear for any drilling environment.*
