How to use Digitrak Mark IV locator

How to use Digitrak Mark IV locator


This page serves as a brief instruction for individuals who have previous experience using equipment similar to the one you have purchased. We strongly recommend that prior to using your equipment, you carefully read the manual that accompanies it. It is essential that you keep the manual with the equipment at all times for future reference. In the event that you require a replacement copy of the manual, please contact your dealer.


Welcome to the DigiTrak Mark IV Locating System Operator's Manual! This guide will help you understand how to use our advanced locating system with ease.

Set up the transmitter: The transmitter is placed inside a housing that is rolled on a flat surface to verify that its clock positions match the display in the top right window. Once this is confirmed, lay a tape measure between the transmitter in the housing and the receiver.

Calibrate the receiver: The calibration procedure is outlined in detail in "Calibrating the Receiver" section of the manual. Follow these steps carefully to ensure accurate depth, pitch, roll, and locate points:

  • 1. Calibrate the system regularly: Regular calibration of the receiver and transmitter is essential for accurate readings. Follow the calibration procedure outlined in the manual carefully to ensure that your system is properly calibrated.
  • Verify distance readings: After calibration, verify that the distance displayed in the bottom window matches the distance on your tape measure at varying distances, particularly 1.5 times your target depth for your intended borepath.
  • Check pitch readings: Place the transmitter in the housing and verify that pitch readings remain the same when the housing is held level and rotated through at least four of the 12 clock positions.
  • Use proper technique: When using your Mark III system, be sure to hold it steady and level to avoid any errors in readings due to movement or tilting.
  • Avoid interference: Interference from other electronic devices or metal objects can affect your readings. Be sure to avoid these sources of interference when using your Mark III system.

To start using the Mark IV system, test it with the Transmitter inside the drill head prior to each drilling run. This will confirm that it is operating properly. Regularly test system calibration while drilling using the ultrasonic function. Always test calibration after stopping drilling for any length of time.

When testing system calibration, make sure that background noise is below 150 and signal strength is at least 250 points above background noise during all locating operations. This will ensure accurate results.

To begin locating with the DigiTrak Mark IV system, turn on the receiver by clicking the trigger once. The Mark IV receiver is also available as an upgrade to Mark III equipment.

Many of the principles are similar in previous DigiTrak systems, so we frequently recommend referring to the DigiTrak Mark III Directional Drilling Locating System Operator's Manual for best practices on how to operate the system.
