Champ Discoverer

The Champ Discoverer electronic multishot is a magnetic drill-hole surveying system designed to make survey data collection processes simpler and easier for the operator.

The hand-held ruggedised tablet communicates wirelessly with the Champ Discoverer probe through an infra-red data link. The timer in the hand-held unit is synchronised with the probe, prior to being lowered into the drill hole, and data is saved into tool memory as each shot is taken.

When the survey is complete, the data is downloaded to the tablet which displays the processed data along with primary quality control indicators including Mag Field, Mag Field Dip, and Gtotal. When exported to Axis’ onTrack™ Survey Analysis Software, further features such as enhanced analysis, survey and 3D graphical views as well as report generation are available to the user.

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.
