Locating in the horizontal directional drilling (HDD) industry was initially based on locating a buried cable by sweeping the locator back and forth to find the highest signal strength (peak signal), indicating that the locator was over the cable. Unfortunately, this method did not always guarantee an accurate location of the cable, nor did it provide any depth information.

This “peak signal” method was adapted to HDD with the introduction of a transmitter that provides information on the position and depth of the drill head. However, this method is unreliable and inaccurate because the peak signal strength is not always directly above the transmitter housing.

In addition, peak signal locating doesn’t show where the drill tool is headed. Think of drilling like driving a car: it is more effective to look ahead through the windshield to see where you are going than to look down at the road through the floorboard to keep the car (drill tool) on the road (drill path).

DigiTrak locators are part of the integrated Digital Guidance System. The system comes standard with a locator, a remote display, a transmitter, batteries, and a battery charger. 

You can purchase additional transmitters, batteries, chargers, and the R1 terrain mapper from your local dealer.

You can find a chart of the compatible transmitters in the "Compatible Transmitters" article of the DCI DigiGuide App.

1. Locator - The locator displays and interprets the information received from the transmitter in the drill housing.

2. Remote Display - A freestanding or drill-mounted, color touchscreen that displays the locator information and rod-by-rod drill information. A core suite of apps is included: LWD Live, Target Steering, Strip Chart, and Frequency Change.

3. Battery cables

4. Locator battery and charger

5. Transmitter - A transmitter generates a magnetic field detected by the Falcon locator. The transmitter must be paired and calibrated to the locator prior to use. The technical specifications in the DCI DigiGuide App list the compatible batteries for each model.

The manuals for the locators and Aurora display are available in the DCI DigiGuide App. Transmitter articles are included in the individual locator manuals in the Advanced chapters.

DCI’s design uses a “locate point” in the transmitter signal. The Front Locate Point (FLP), which is out ahead of the transmitter, shows where the transmitter housing is heading.

DCI invented the Ball-in-the-Box user interface to make it quick and intuitive to find a locate point, speeding up drilling jobs: just move the locator so the ball moves into the box on the screen.

Finding a locate point also helps you find the drill head itself.

There is a second locate point behind the transmitter called the Rear Locate Point (RLP). The two locate points, combined with a Locate Line (LL), pinpoint the precise location of the transmitter housing below ground.

They are arranged like an airplane, where the Front Locate Point is the plane’s nose, the Rear Locate Point is the tail, and the Locate Line is the wings.
 

If your drill path requires a consistent depth or to maintain a constant pitch, use the predicted depth feature at the Front Locate Point. This eliminates the need for depth readings over the transmitter, speeding up the drilling process.
 

Interference can cause incorrect locate data that reduces locating accuracy. There are two different types of interference that can distort the transmitter signal: active and passive.

Active interference, or “noise”, consists of anything that emits a signal that interferes with the transmitter signal. Example sources include power lines, radio towers, cathodic protection, fiber tracer lines, invisible dog fences, security systems, and traffic signal loops. Falcon’s frequency optimizer finds the best frequencies to avoid noise.

Passive interference consists of anything that blocks or distorts the transmitter signal resulting in incorrect depths or missing data. Example sources include rebar, guard rails, bridge abutments, chain link fencing, salt/saltwater, and soil high in metal ore. The Falcon sub-kHz transmitter (available for Falcon F5 and F5+ only) helps cut through passive interference without distorting the signal.

An A on the screen can indicate signal Attenuation due to the presence of excessive interference, which can make depth readings inaccurate. Attenuation is normal in shallow depths less than 8 feet (2.4 m). If the signal strength is also flashing, this indicates extreme interference. Depth and locate points may be compromised and the locator will not calibrate.

Noise varies by amount and frequency depending on where you are and even the time of day. That’s why it’s important to find the best frequencies for every bore.

This is called frequency optimization, and only Falcon has it. Using frequencies with the highest probability of success against noise increases locating accuracy and reduces the risk of tripping out.

Falcon’s frequency optimizer scans through hundreds of frequencies, then bundles those with the lowest noise into finely-tuned bands that work best for the current job.

Select two bands and switch between them mid-bore if needed (not available on the Falcon F1 with singleband).

The Falcon Plus locators with Quick Scan Pair offer features to make the selection of bands faster and easier. Two clicks select the two preset bands selected for your region.

Falcon F Plus line of locators has a toggle switch on top and a trigger switch under the handle to navigate the menu system and select options.

Use the 4-way toggle switch to access a menu, move between menu options, and open shortcuts.

Shortcuts require you to hold the toggle for a second or longer; we call this a “hold toggle”. For example, from the Locate Mode screen, open a transmitter band selection shortcut by holding the toggle right.

Use the trigger switch to power on the locator, select a menu option, and to take a depth reading.

Pull and release (click) the trigger to select. In some cases, you’ll need to hold the trigger for a second or more to use a function, such as turning the locator on or taking a depth reading.

Utilities increasingly require a digital as-built report to ensure drilling parameters were met.

The DataLog® feature on your locator lets you easily capture and store the rod-by-rod data of your pilot bore.

When used with DCI’s DigTrak LWD app, geo-tagging the entry and exit automatically ties the as-built to a physical location.

With a DigiTrak LWD subscription, use your mobile device to upload DataLogs to your cloud account even during drilling to show progress to back-office personnel.

After importing your DataLog job into our Log-While-Drilling (LWD) software, you can edit, annotate, and finalize the precise report you or your customer requires.

On the DigiTrak Aurora remote display, use our free LWD Live app to view the drill profile in real-time as each rod is completed.

The Locate Mode, Depth, and Predicted Depth screens are the primary screens you will use for locating.

When the locator is detecting a signal from a transmitter, the Locate Mode screen provides real-time data about the transmitter’s location, temperature, pitch, roll, and signal strength.

Depth data appears when the trigger is held at the Locate Line (LL) and predicted depth appears when held at the Front Locate Point.

1. Locating ball (FLP or RLP)
2. Yaw indicator
3. Locator
4. Roll indicator
5. Roll value
6. Roll/pitch update meter
7. Transmitter pitch
8. Power Mode and Transmitter signal strength
9. Transmitter fluid pressure
10. Transmitter temperature

The Depth screen displays when the trigger is held with the locator at the Locate Line (LL).

1. Locate point (front or rear)
2. Bird's-eye view
3. Locate Line (LL)
4. Height-Above-Ground (HAG) setting on
5. Ground level
6. Transmitter depth
7. Transmitter battery strength
8. Transmitter power level

The Predicted Depth screen displays when the trigger is held with the locator at the Front Locate Point (FLP).

1. Ball-in-the-Box at FLP
2. Reference Lock * indicator
3. Transmitter battery strength and pitch angle
4. Horizontal distance between transmitter and FLP
5. Predicted depth * of transmitter

The predicted depth is the depth the transmitter is calculated to be at when it reaches the FLP if it continues on its current path.

In this example, if the drill head travels an additional 3'8" (1.12 m) at -0.6% pitch, it will be directly below the locator at 2'8" (0.81 m).

Before scanning with the Frequency Optimizer (FO) you have three options to select which bands to pair with your transmitter.

Basic - Quick Scan Pair (QSP) – With fewer clicks, bypass the FO to scan and pair the pre-selected Up and Down bands for your region.

Advanced FO - Quick Pick – After scanning, use the two bands with the lowest noise indicated by the FO with white arrows.

Advanced FO - Manual Pick – After scanning, select one or both bands and assign them to up or down.

After using one of the Advanced methods to pick the bands, you will pair them with the transmitter and then calibrate.

Calibration is required any time you change your transmitter, locator, drill head, power setting, or perform a new frequency scan and then pair.

Calibrate both bands with the transmitter in the housing (flat on the ground in a low-noise, metal-free environment) immediately after pairing.

When a transmitter is level (zero pitch) underground:

• the locate points (FLP and RLP) are at equal distances from the transmitter
• depth displayed on the locator is the actual depth, and
• the Locate Line (LL) indicates a position above the transmitter.

1. RLP
2. LL
3. FLP

When the transmitter is pitched up or down, the transmitter signal field also tilts.

When the transmitter is pitched down (negative pitch), the locate line on the screen reflects a future position of the transmitter, assuming the transmitter stays on the same trajectory (projected depth).

When the transmitter is pitched up (positive pitch, shown below), the locate line on the screen reflects a position behind the transmitter.

The depth reading on the locator is based on the projected depth point, which is not the same as the actual depth of the transmitter.

1. RLP
2. FLP
3. LL
4. Fore/aft offset
5. Projected depth
6. Transmitter at positive pitch
7. 30% (17°)

The differences in position and depth between the projected depth point and the actual location of the transmitter can be relatively small at low pitch and/or shallow depth.

When drilling at a steep pitch and/or significant depth, the differences are greater.

For example, if the transmitter is at a plus or minus 30% pitch and a 33'1" (10.1 m) depth, the locator depth reading will be 35' (10.7 m) (just under 6% difference from actual depth) and the locate line will be 6'6" (2 m) from being directly above the transmitter (-30% places the LL ahead and +30% places the LL behind).

You can use the pitch and the projected depth reading on your locator to determine the actual depth and the position (fore/aft) of the locate line:

Actual Depth

Fore/Aft Offset

For a given pitch, you can calculate actual or projected depth:

This calibration procedure is rarely needed. If you find it necessary to calibrate with the transmitter in the ground, contact DCI customer service for information on this option, and perform the procedure with caution.

V2 Transmitters have three power modes to balance signal strength and battery life. V2 transmitters are etched with a "V2" on the stainless battery compartment (not on the label) and have a multipower mode sticker around the IR port.

If used with a Falcon without the programmable power mode, the mode selected while pairing the Tx determines the signal range and the battery life.

Falcon locators with programmable power mode override any other selection method when used with a V2 transmitter.

1 For Falcon locators with programmable power mode, Low power also gives you a faster pitch update rate

2 FT2L+ V2 is only compatible with Falcon+ locators.

3 F1 Low and standard power only

4 Range is based on SAE Standard J2520 in AGR mode and Max Mode. Actual range and battery life will vary based on interference, transmitter housings, and frequencies.

The battery types listed are the only types recommended for that model and size. DCI does not recommend using other battery types. *Lithium Rechargeable (LiR) battery life is based on 21700 battery with 5000 mAh rating. with a max 4.2 volts. Battery life while asleep is 400 hours for SuperCell and 200 hours for alkaline. Sleep mode starts 15 minutes after last roll change.

FTR (Sub-k Rebar) Tx's do not have MultiPower mode and have Standard power battery life. Depth/data range for Up Band is similar to Standard power; Down band is similar to Low power mode.

You can see the power mode selected for each band on the Transmitter Info screen. See "Get Transmitter Info" for steps.

You can also see the Power mode of the current band on the Locate Mode screen and the TX Info pairing screen.

Depth Increase in Inches (cm)

Slopes between 50% and 100% are provided for reference only and do not represent typical drilling conditions. All numbers are based on math only and do not take into account extremely soft or extremely hard soil conditions, which may cause depth values to vary.

If you know the transmitter pitch, the positions of the front locate point (FLP) and the rear locate point (RLP), and if the ground surface is level, you can still estimate the transmitter depth even if the depth information displayed on the locator becomes unreliable.

To estimate the transmitter depth, first measure the distance between the FLP and the RLP. The pitch of the transmitter must also be reliably known. Using the Depth Estimation Table below, find the divider that most closely corresponds to the transmitter pitch. Then use the following formula to estimate the depth:

Depth = Distance between FLP and RLP / Divider

For example, if the transmitter pitch is 34% (or 18.8°) then the corresponding divider value (from the table) is 1.50.

In this example, the distance between the FLP and the RLP is 11.5 ft. The depth would be:

Depth = 11.5 ft. / 1.50 = 7.66 ft.
