8500 Tracking System Operator’s Manual Tracking Concepts - 49
Theory of Operation
CMW
Drill-Thru
The tracker calculates the beacon’s current depth, horizontal distance to the tracker and the predicted
depth at the tracker position. The tracker allows you to drill toward, under and away from the tracker while
providing depth and horizontal distance. The horizontal steering guides the operator to the intended bore
path, assuming a straight line along the tracker.
