Feasible Target Steering Area
The maximum distance the receiver can be placed ahead of the drill head for Target Steering is 10.7 m.
Beyond this distance, depth information becomes less accurate. Within this range, starting with the drill head
approximately level, the following parameters apply to depth data:
l The maximum depth change is approximately 1.2 m.
l The maximum pitch change is approximately 14%.
For the most conservative Target Steering operation, assume the ideal drill path is a circular arc with a radius
that accommodates the bend radius of most drill strings and products being installed. As shown in the
diagram below, the feasible steering area is limited to the shaded region bounded by the two circular arcs.
1. Surface of ground
2. Current depth
3. Horizontal distance 10.7 m max
4. Transmitter
5. Target (2)
6. Feasible target steering area
7. Minimum target depth
8. Depth change 1.2 m max (2)
9. Maximum target depth
Feasible Target Steering Area
The Target Steering procedure requires correct placement of the receiver at less than 10.7m in front of the
transmitter, on the bore path, with its back end (where the battery pack is inserted) facing the drill.
Turning Target Steering On
The target depth is the depth at which you want the transmitter when it reaches the location under the
receiver. To set the desired target depth on the receiver, toggle up at the Locate screen to open the Target
Steering menu.
