Before You Start
This article assumes that the bore plan was created in the R1 app and then transferred to the Aurora remote display. For instructions, see the DCI DigiGuide app article "Transfer Plan to Aurora Display" in the Jobsite Setup chapter in the Aurora Display manual.
Three key best practices
To get the best results when using the R1 bore plans on the Aurora, there are three key points to consider.
Match the entry point of the bore to the R1 plan
- Match the entry point of the bore to the R1 plan
- Log the first rod accurately
- Log depth data at the Locate Line over the transmitter housing
Match the entry point of the bore to the R1 plan
It is critical that the entry point from the R1 plan and the physical entry of the drill head into the ground are “the same”. In other words, if the entry point from the plan is 20 feet from the edge of a road, and the machine was set up where the drill head enters the ground 25 feet from the road, the plan and the data logged in LWD Live will never match.
If the machine cannot be moved, then edit the entry point in the R1 plan to move it 5 feet further from the road and then retransfer the plan to the Aurora.
For details, see the chapter "Use Terrain Data" in the DCI DigiGuide App TeraTrak R1 manual.
Log the first rod accurately
The workflow walks you through the necessary steps, but it is key that the first data point is logged when the drill head is halfway into the ground. The image from the Configure app illustrates how to do that.

The app will only allow you to proceed if you have a pitch reading from the transmitter. |
Without pitch data
 |
This screen displays the target pitch for the first data point as -20.0%, but there is no live pitch data. The checkmark is greyed out, and the data point cannot be logged. |
With pitch data
 |
This screen displays the pitch reading as -20.5%. This is close enough to start the bore, and the first data point can be logged. |
Log depth data over the transmitter housing at the Locate Line
The R1 bore plan displays the planned depth and pitch at the end of the rod. The R1 app calculates the planned depth from the depth reading over the transmitter housing. It is therefore essential that when logging data in LWD Live, the locator takes a depth reading at the Locate Line over the transmitter housing.

If depth reading can not be taken over the drill housing (if there is an obstruction for example), log the pitch only. |
| To log pitch only, tap the green depth button so it turns orange before tapping the check mark. This results in a blank topography point on the graph (when not using R1 plan data). |  |
| If a depth reading is not available, the depth button will already be orange. |  |
