Page 3: New Project
The Project window appears. At this stage you can import pre-surveyed and pre-designed holes into Carlson Boretrak. This allows you to plan your field operations better and to see in near real-time the deviation and layout of your drilled holes. - Page 4 Select a CSV file containing hole data. Then define the fields within the file. Select the column header, then select the correct field from the drop-down Data list. After the last column header, tap Confirm. Then tap Import.

- Page 6 Carlson Boretrak automatically starts searching for your probe. If no connection is made, check: • The Boretrak2 probe is powered ON and flashing red or blue. • The Boretrak2 is paired to your tablet. • Bluetooth on your tablet is switched ON.
- Page 7 4 Alignment Position the probe on the alignment jig. With the probe lying on the alignment jig, tap Align Gyro. If you have pre-existing holes in the project with real-world coordinates, you can use these to align the gyro. Hole 2 Probe on alignment jig pointing from hole 1 to hole 2...
- Page 8 When you carry out an alignment, the Alignment Details window appears. Tap Relative, then select the appropriate hole numbers in the From and To drop-down list. The alignment heading is computed. Alternatively, you can just enter a known heading. The required heading is always that pointing along the probe towards the nose cone.
- Page 9 5 Deployment Check you are set to survey the correct Hole (01) and the correct Segment length (2m). Now you are connected and ready to survey. Deploy the probe so the tip of the nose cone is 2m past the collar. First nodule on cable Probe lowered until second nodule is level...
- Page 10 Hold the probe steady and tap Take Reading. After the first reading the 2m Segment length is added to the 3D View and to the Length display The process of collecting Boretrak readings during the deployment is entirely manual. o Don’t forget to take a reading at every segment length (in this case, 2m) o Don’t take more than one reading at a segment length o Only deploy by the selected segment length BT2 Quick start operational guide...
- Page 11 As the probe descends, the Bluetooth link will cut out. Carlson Boretrak manages this link automatically and will re-establish the link when the probe is recovered. The live read out disappears while the Bluetooth link is broken. Tap Undo Last if...
- Page 12 Recover the probe from the hole. A Bluetooth link is automatically re-established when the probe is within range of the tablet. You may see some data being downloaded from the probe to Carlson Boretrak. BT2 Quick start operational guide P a g e | 12...
- Page 13 Select the next hole (02) from the Survey Next Deployment drop-down list. Tap Deploy to Hole 02 to begin the next deployment. Take the probe and deployment device to the next hole. You are ready to deploy down Hole 02 Tap zoom to show the new hole in the 3D...
- Page 14 6 Re-aligning The gyro accuracy degrades over time after an alignment. You should carry out a re-alignment as often as possible. For the very best accuracy, realign before each hole. A reasonable target would be to align every three or four holes, but this will depend on the length of each deployment, the required accuracy for your project and the practical realties of positioning the alignment jig on your site.
- Page 15 If you have not moved the alignment jig since the previous alignment, you can use the same heading as before. Tap Use Existing and select the previous alignment from the drop-down list Otherwise, re-position the alignment jig along a new line of known heading. Enter the new heading and tap Finish to confirm the alignment.
- Page 16 7 Check data When readings are taken while the probe is inside the hole there will usually be no Bluetooth link between the probe and the tablet. During this time, the hole readings represented in the 3D View are just ‘placeholders’, which will be overwritten when Bluetooth connection is re-established. The Deployment icon in the Project The hole flashes...
- Page 17 8 Post processing All hole coordinates and alignment headings can be entered retrospectively. In the Project tab, click on a hole, then on the Hole Details button to edit hole coordinates and planned hole details From the Menu tab, Tap on the appropriate tap Alignments alignment to edit the heading BT2 Quick start operational guide...
- Page 18 9 Analysis and Deliverables Click on any item in the Project tab to view details. Click on a Deployment icon, then on the Details button just beneath it. The Deployment Details window opens. You can access views of the deployment, details of each reading, and a comparison with the design.
- Page 19 Reports and exports are accessed from the Menu tab. Reports and exports both allow you to select the holes and deployments which are included in the deliverable. By default, only surveyed holes are included. For exports, select the required export file type, and then select the data required. Change the selection as required, then tap Export.
- Page 20 For reports just select the required data. Change the selection as required, then tap Print to generate a report, or Show to open the report in a PDF viewer. BT2 Quick start operational guide P a g e | 20...
