Note After learning the concepts of Target Steering, practice its use before
using on a jobsite where time and money are at a premium. If you need
further assistance, please contact DCI Customer Service.

You can find a training animation on Target Steering at www.youtube.com/dcikent.
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:
 The maximum depth change is approximately 4 ft.
 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.
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.
