Before each drilling run, test your DigiTrak guidance system with the transmitter inside the drill head to confirm it is operating properly and providing accurate drill head location and heading information.
During drilling, the depth will not be accurate unless:
- The receiver has been properly calibrated and the calibration has been checked for accuracy so the receiver shows the correct depth.
- The transmitter has been located correctly and accurately and the receiver is directly above the transmitter in the drill head underground or at the front locate point.
- The receiver is placed on the ground or held at the correct height-above-ground distance, which has been set correctly.
Always test calibration after you have stopped drilling for any length of time.
