System Operation - 34 8500 Tracking System Operator’s ManualBeacon Tracking OverviewCMWBeacon Tracking OverviewThe tracker has two modes: walkover location and drill-thru. Use walkover location mode to find position of the beacon. Once tracker is in or near the beacon plane, select the depth view to determine the depth and the left/right offset. With tracker in front of and parallel to beacon, press the L/R button while in the main locate view to see the projected path of the beacon. In drill-thru mode, the tracker is placed along the intended bore path and provides the necessary steering corrections for the drilling unit operator to drill that path.Setup1. Install battery in beacon.2. Place beacon in beacon housing away from metal objects. 3. Set up beacon and tracker 10’/305 cm (A) apart, as shown. 4. Select “Beacon Calibration” in “Beacon Settings” menu and follow prompts. See page 21.Potential radio frequency (RF) hazard. Operating this device within 4” (100 mm) of your body may cause RF exposure levels to exceed FCC RF exposure limits and should be avoided.NOTICE: • This device must not be co-located with any other radio transmitter. • The maximum antenna gain is 2.5 dBi.IMPORTANT: • Error conditions will be reported onscreen below diagram.• Pressing “clear” button will restore factory default. This will not provide accurate depth and offset measurements. Calibrate beacon and tracker properly.• Pressing “cancel” will exit calibration menu without changing tracker’s calibration.• If using a dual-frequency beacon, calibrate both frequencies.

System Operation - 38 8500 Tracking System Operator’s ManualWalkover Location ModeCMWProcedureThe 8500 tracking system provides three ways to locate a beacon using walkover location mode. Choose which method to use based on your tracking situation.Single-Point LocationIf concerned with ghost signals or bore path is unknown, use single-point location to find general location of beacon.1. Position tracker parallel (shown) to suspected bore path.2. Walk along bore path until solid and hollow circles are approximately centered in field balance bar.3. Rotate tracker 90° so that tracker is perpendicular to bore path.4. Move tracker left or right to center both circles. Tracker is now roughly over the beacon.5. To locate beacon more precisely, follow peak or advanced location procedure.Peak LocationIf beacon depth is greater than 30’ (9 m), use peak location procedure to position tracker over beacon. This procedure works well at any depth. 1. With tracker perpendicular to bore path (shown), follow locate arrows to beacon plane.2. Move tracker laterally until signal strength is minimized.3. Place tracker on the ground and press SEND button to take depth reading and send it to display.The signal strength reading is the approximate distance from the beacon in inches. A reading of 122 means the tracker is 122” (3.1 m) from the beacon. This reading reflects how many inches the tracker is from the beacon regardless of the units setting in the display menu.
8500 Tracking System Operator’s Manual System Operation - 39Walkover Location ModeCMWAdvanced LocationIf beacon depth is less than 30’ (9 m), use advanced location procedure to position tracker over beacon.1. With tracker perpendicular to bore path, follow locate arrows to beacon plane.2. Place tracker on the ground and press DEPTH button. If desired, move tracker side-to-side until offset is at 0.3. Press SEND button to take depth reading and send it to display. Press and hold SEND button for 1/2 second if 0.1” (1 cm) precision is required.Quick RangeTo get a quick estimate of how far away the beacon is, press the SEND button while the tracker is in walkover locate view. The average of the distance to the beacon for each pod will be displayed in place of the signal strength.Projected Direction1. Hold down the L/R button to switch from fore-aft arrows to left-right arrows. 2. Move approximately 10’ (3 m) in front of the beacon position and rotate tracker until tracker is parallel with bore path with left antenna pod closer to drilling unit. 3. Align arrows to check beacon heading. 4. When arrows turn solid, the projected depth will be displayed in a dotted box (shown below) in place of the signal strength value.

Tracking Concepts - 48 8500 Tracking System Operator’s ManualTheory of OperationCMWTheory of OperationSystem OverviewThe 8500 tracking system uses a magnetic field generator in an 850 series beacon and two receiving antenna pods in an 8500TK advanced tracker to determine beacon position. The tracker detects the generated magnetic field and calculates the beacon’s position. Downhole information is relayed from the beacon to the tracker. The tracker sends all received and calculated data to a remote display over a radio link.The dual antenna pod design provides the ability to approach the beacon location without encountering ghost signals and can determine the beacon’s location and heading. When placed along the intended bore path, the tracker can be used in Drill-Thru mode to provide the beacon’s current depth, projected depth at the tracker location, horizontal distance (range) and horizontal steering correction.Beacon PlaneThe 8500TK locates the beacon plane perpendicular to the center of the beacon. Once the tracker is within range of the beacon and within the beacon plane, the advanced depth calculations of the tracker are enabled. The beacon plane extends outward from the center of the beacon and runs perpendicular to the beacon as shown. Because of this, the ground level location may be slightly in front of or behind the true vertical position of the beacon’s center. This is only apparent at extreme pitches and increasing depths. For example, at 30’ (9 m) deep and 10% pitch, the beacon plane and vertical plane will be approximately 3’ (914 mm) apart at ground level. The tracker calculates this difference and presents it in the depth mode side view.Beacon plane: side viewBeacon plane: top view
8500 Tracking System Operator’s Manual Tracking Concepts - 49Theory of OperationCMWDrill-ThruThe tracker calculates the beacon’s current depth, horizontal distance to the tracker and the predicted depth at the tracker position. The tracker allows you to drill toward, under and away from the tracker while providing depth and horizontal distance. The horizontal steering guides the operator to the intended bore path, assuming a straight line along the tracker. Sample beacon positions and resulting horizontal steering correction arrows.
Tracking Concepts - 50 8500 Tracking System Operator’s ManualGhost Signal ResponsesCMWGhost Signal ResponsesThe locate arrows will change direction and point away from the beacon (as shown) as the tracker reaches a ghost signal. The distance from the beacon plane to the ghost signals increases with increasing depth. To avoid locating ghost signals, rotate tracker parallel to bore path (shown below) and watch the solid circle in the field balance bar to get near the beacon plane.
