Using the receiver for Target Steering requires a stable signal from the transmitter.
Target Steering will not work properly with passive interference in the vicinity of
the bore.

Feasible Target Steering Area
The maximum distance the receiver can be placed ahead of the drill head for Target Steering is 35 ft. 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 4 ft.
l
The maximum pitch change is approximately 14%.
When used to provide only the right/left Remote Steering signals accepted by the Falcon Compact Display,
the distance between receiver and transmitter is limited only by the range of the transmitter.
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.

Feasible Target Steering Area
The Target Steering procedure requires correct placement of the receiver at less than 35 ft. in front of the
transmitter, on the bore path, with its back end (where the battery pack is inserted) facing the drill.
Use the three screens in the Target Steering menu
on the receiver to turn Target Steering On, turn
Target Steering off, or set the target depth, as described in the following sections.
