Target Steering on Remote Display
The steering indicator in this case shows that the drill head is to the left and too high for the intended
path. The steering indicator should be dead center in the display if you are correctly heading to your
programmed target depth. A steering command of 4 o’clock would bring the drill head toward the target.
Note that, for quick viewing and interpretation, the pointed end of the steering indicator corresponds to the
clock position of the head. The horizontal distance from the drill head to the receiver is indicated at the
bottom left part of the display. At the bottom right, the current depth of the drill head is indicated.
A side view of the position of the receiver and of the transmitter is shown below on the left. An end view of
the same setup is shown on the right.
