In the world of horizontal directional drilling (HDD), precision and reliability are paramount. Drilling professionals rely on advanced locating systems to guide drill heads underground, avoiding obstacles and hitting targets with accuracy. The DigiTrak F2 locator and its transmitters (sondes) have proven to be an ideal solution for obtaining precise, reliable data during drilling operations. This mid-range locating system, part of DCI’s Falcon series, is renowned for its ability to maintain strong signal readings even in challenging conditions. Many HDD crews consider the DigiTrak F2 a trusted workhorse that delivers the information needed to steer drills with confidence on job sites worldwide.

For example, the image below shows a DigiTrak F2 locator (right) alongside an FSD™ remote display (left) and other typical accessories.

These components together form a comprehensive guidance system that helps drill operators “see” the drill head’s location and orientation underground. By reviewing the capabilities of the F2 system and its accessories, drilling professionals can better understand how this technology can benefit their projects.

Overview of the DigiTrak F2 System

A standard DigiTrak F2 system consists of a handheld locator (receiver), one or more transmitters (sondes) placed in the drill head, and optionally a remote display for the drill rig operator. The F2 locator is used by a crew member at the surface to track the position, depth, and angle of the sonde in real time as the bore progresses. Data is transmitted from the sonde to the receiver, and key information (like depth, pitch, roll, temperature, battery status) is displayed on the locator’s screen. When paired with a remote display (such as the DigiTrak FSD or the newer Aurora 8.4″ touchscreen), this information can be relayed to the drill operator’s station in real time. This means the driller doesn’t have to rely solely on radio calls or hand signals – they can directly monitor drilling parameters as they steer.

Rugged Design: The F2 receiver is built for tough job site conditions, with a durable housing that protects its electronics from mud, shocks, and weather. It’s designed to be user-friendly and ergonomic, so crews can operate it all day. The unit’s reliability under harsh conditions has made it a preferred locator on thousands of job sites worldwide. When project failure is not an option, having a dependable locator like the F2 is critical to success.

How It Works: During drilling, the sonde (transmitter) in the boring tool sends out an electromagnetic signal. The F2 locator picks up this signal as the operator walks above the bore path. Using directional antennas and Ball-in-the-Box™ guidance technology (a feature of DigiTrak systems), the F2 provides intuitive feedback to the operator on where the transmitter is relative to the target line. Essentially, the locator helps the operator “follow” the drill head by indicating alignment (left/right) and front/back positioning via the ball-in-box display, ensuring the bore stays on course. At the same time, the locator continuously measures depth and pitch angle, allowing the crew to know if the drill head is rising, dropping, or level. This real-time guidance is invaluable for navigating beneath obstacles and achieving the desired bore path on the first attempt.

Key Features of the DigiTrak F2

The DigiTrak F2 Falcon system comes packed with features that set it apart from older locating systems. Notably, it was engineered to cut through interference on busy jobsites and provide stable readings where other locators struggle. Below are some of the key features and technologies that drilling professionals will appreciate:

• Dual Frequency Operation: As the “F2” name suggests, the system can operate on two selectable frequencies. This dual-frequency capability allows crews to choose a frequency band that minimizes interference in a given environment. The Falcon technology actually scans over 500 channels within its range to identify the quietest signal bands, then lets you optimize the system using a single transmitter. In practice, this means common sources of interference like power lines, traffic signal loops, or buried metal fences are far less likely to disrupt your readings. The result is more consistent performance in both urban and remote jobsites.
• Active Interference Mitigation: Building on the point above, the F2 features an Active Interference Slayer function. It continuously analyzes incoming signal quality and automatically adjusts or recommends adjustments to mitigate real-time noise. This dynamic filtering gives operators confidence that the depth and location data they see is accurate, even if the environment is electrically noisy.
• Ball-in-the-Box™ Guidance: This is DigiTrak’s proven target tracking technology that simplifies navigation. A graphic “ball” indicator on the F2’s display shows the drill head’s position relative to the desired bore path (the “box”). By keeping the ball centered in the box, operators can navigate confidently and ensure the bore stays within the planned trajectory. This intuitive visual guidance significantly helps less experienced crew members follow the tool, and it provides an extra layer of assurance for seasoned operators working on critical crossings.
• Quick Scan and Pairing: The DigiTrak F2 makes setup faster with its Quick Scan Pair feature. With just a couple of clicks, the locator scans for interference, suggests the best frequency, and pairs with the transmitter. This means you can get to drilling faster instead of fiddling with manual frequency tuning. In the field, saving time on setup can translate to completing bores sooner and reducing crew downtime.
• Depth and Range Performance: The F2 offers an impressive locating range for a mid-tier system. The original Falcon F2 model already had strong capabilities, and the updated F2 Plus variant extended this further with an increased depth range of up to 160 ft and data transmission range up to 200 ft in optimal conditions. Even with the standard F2, operators can typically reliably track depths well beyond 85–100 ft (depending on soil conditions and transmitter used). This kind of range covers the majority of utility installations and small-to-medium pipeline bores. For jobs that require even more distance or depth, operators might step up to the five-frequency Falcon F5 system, but for most routine HDD projects, the F2 is more than capable.
• Multi-Power Modes: The DigiTrak F2 transmitters support multiple power settings (low, standard, and high output). The locator and transmitter can be easily toggled to a higher power mode when attempting a deeper bore or when more signal strength is needed, and conversely to a low-power mode to conserve battery life when working at shallow depths. This flexibility lets crews balance performance and battery usage on the fly. Higher power modes combined with extended-life batteries enable longer drills without interruption, whereas lower power can significantly extend transmitter battery life on simpler shots.
• Rugged & Reliable: Both the F2 locator and its accessories are built to endure harsh environments. The system’s components are typically rated to withstand typical HDD jobsite hazards – from accidental drops and vibration to water and mud ingress (the transmitters, for example, operate inside drilling fluid and high temperatures). Reliability is a major selling point: the F2’s track record on countless jobsites has shown it to deliver consistent, accurate results day in and day out. This dependability reduces the risk of costly mistakes or project delays due to locating errors.

F2 Transmitters (Sondes) and Compatibility

No locating system is complete without its transmitters, and the DigiTrak F2 offers a versatile lineup. The transmitters (also called sondes) are the heart of the system, residing in the drill head housing and sending out signals that the F2 receiver picks up. F2 transmitters come in various models to suit different drilling needs and conditions. In fact, one of the strengths of the F2 system is its compatibility with a range of transmitter types:

• Standard-Range Transmitters: The common options are the FX12 and FX19 sondes, which operate at 12 kHz and 19.2 kHz respectively. These are about 15 inches long and are considered standard-range, capable of handling most everyday drilling tasks. The two different frequencies give crews flexibility; for instance, if the 12 kHz band is experiencing interference at a jobsite, switching to a 19.2 kHz sonde (and frequency on the receiver) can yield a cleaner signal, and vice versa.
• Extended-Range Transmitters: For deeper bores or longer shots, extended-range versions are available. The FXL12 and FXL19 are 19-inch transmitters (noticeably longer because they can accommodate larger battery packs) and operate on the same 12 kHz and 19.2 kHz frequencies. The longer size means they can transmit stronger signals or simply last longer on a battery, enabling greater depths and extended drilling time. These are particularly useful when you anticipate pushing the limits of depth or drilling in difficult soil conditions where signal attenuation is higher.
• Short-Range (Compact) Transmitter: The F2 system can also work with a short 8-inch transmitter, often referred to by the code FS (12 kHz Short Range). This compact sonde is handy for small diameter drills or tight situations where a full-size housing won’t fit. While its range is more limited, it still provides the same essential data for shallow utility installations or branch lines where a standard sonde would be overkill or physically impractical.
• Cable Transmitter: Uniquely, the F2 supports a cabled transmitter (FC, 12 kHz). This 19-inch sonde can be hard-wired to a surface power source and data link. The cable transmitter is extremely useful in scenarios with extreme interference or when drilling in conductive ground (like near railroad tracks or reinforced concrete) that would normally distort or dampen wireless signals. By using a direct cable connection, you essentially bypass the signal loss and can maintain reliable tracking in conditions that would defeat ordinary wireless transmitters. It also means you don’t have to worry about transmitter battery life on very long bores – the transmitter can be powered continuously from the surface. The trade-off is the hassle of managing a wire and the need for a specialized setup, but for certain critical bores it can be a lifesaver.

All the F2 transmitters share some common traits: they typically provide data on drill head pitch (angle), roll (clock position), depth, and some models include temperature monitoring to alert if the tool is overheating. They are sealed to handle drilling fluid and pressure, and have specific battery requirements (usually C-cell lithium batteries or battery packs). Using genuine DigiTrak battery packs or high-quality lithium cells is important to ensure optimal performance and to avoid downtime from power loss mid-bore.

Remote Displays and Accessories

To fully leverage the DigiTrak F2 system, many drilling crews utilize remote displays in addition to the handheld receiver. A remote display mounts near the drill rig operator (for example, on the drill console) and mirrors critical data from the locator in front of the person steering the drill. This setup turns HDD into a more efficient one-person operation at the rig, as the driller can glance at depth, pitch, and target steering cues in real time without relying on another crew member relaying info.

Several remote display models are compatible with the F2 locator, each with its own features:

• DigiTrak FSD: This is a classic Falcon Screen Display, a rugged monochrome remote that shows basic data like depth, pitch, and left/right steering indicators. It’s wireless and built tough for outdoor use. An FSD is straightforward and reliable – ideal for those who want just the essentials displayed on a simple screen.
• DigiTrak MFD: The Multi-Function Display is another option, offering a bit more information or different screen modes. It provides the same telemetry and can often display additional info such as battery status or warnings in text form. It’s slightly more advanced than the FSD but serves a similar purpose of keeping the driller informed.
• DigiTrak Aurora: The Aurora AF8 is a modern 8.4-inch touchscreen display introduced by DCI in recent years. It features a full-color interface and can run custom apps or logging software (like DigiTrak’s LWD – Log-While-Drilling). When paired with an F2 receiver, the Aurora can present data in a very user-friendly visual format, possibly including bore log graphs, GPS mapping integration, and more. It essentially brings advanced tech to the drilling rig, allowing for things like bore planning and data recording on the fly. For tech-savvy crews or complex projects, the Aurora remote display can be a game-changer.

Using a remote display with the F2 is optional, but most professionals highly recommend it. It increases safety and efficiency: the driller doesn’t need to take their eyes off the controls or rely on verbal calls for every reading. Instead, they see immediate feedback if the tool face orientation changes or if the depth is approaching a critical limit, etc. This immediate awareness helps prevent mistakes like over-shooting a target depth or deviating from the bore path, especially in sensitive crossings.

Batteries and Chargers: Both the F2 locator and the remote displays use rechargeable Lithium-Ion battery packs. Modern Li-Ion packs offer long run times and don’t have the “memory effect” issues of older NiCad batteries. Typically, an F2 uses a battery pack that slots into its handle, and the remote displays use similar packs. Having multiple battery packs on hand is wise – one can charge while another is in use, ensuring the equipment stays powered through long drilling days. Fast chargers are available and can recharge a spent pack in just a couple of hours. Additionally, for transmitters (sondes), there are specialized battery sticks (often two welded C-cell lithium batteries or proprietary PowerCell packs) that power the sonde. Extended-life transmitter batteries (like the aftermarket “SuperCell” or “PowerCell” options) can significantly increase the transmitters’ run time, which is especially useful on lengthy bores or when using high-power mode. Drilling professionals often keep a stock of fresh transmitter batteries so they can swap them out at every drill rod or as needed to avoid losing signal due to a dead battery.

Other handy accessories for the F2 system include sturdy carrying cases (to protect the sensitive electronics during transport), harnesses or chest straps for the locator (so the operator can hold it steady and reduce arm fatigue), and calibration tools or test blocks for verifying the locator is working correctly before a job.

Benefits of the DigiTrak F2 for HDD Projects

Choosing the DigiTrak F2 system brings several important benefits for horizontal drilling projects:

1. Enhanced Jobsite Confidence: With its interference-fighting Falcon technology and reliable performance, the F2 gives crews confidence even in busy, electrically noisy environments. Knowing that the locator is actively finding the best frequency and filtering noise means operators can trust the depth and directional data it provides. This confidence translates into quicker decision-making and smoother drilling – contractors can tackle jobs beneath power corridors or urban streets without as much worry about signal loss or false readings.
2. Improved Accuracy and Reduced Rework: Accurate locating is directly tied to job success. By using a precise locator like the F2, drilling professionals can hit bore targets more consistently. The system’s guidance features (like ball-in-the-box) help prevent deviations, so bores come out where intended. This accuracy reduces the need for costly re-drills or realignment due to going off course. It also minimizes the risk of underground strikes – the F2 can help the crew proactively avoid existing utilities by clearly delineating the bore path during tracking.
3. Efficiency in Operations: The F2’s quick setup and user-friendly interface mean less downtime spent on equipment fiddling and more time drilling. Features like Quick Scan Pair expedite the start-up, and the ability for one person to monitor the remote display at the rig while another walks with the locator makes the whole operation more efficient. Fewer stoppages and clear communication via technology can speed up project completion times, which is a win for both contractors and clients.
4. Versatility Across Jobs: Because the DigiTrak F2 supports multiple transmitters and frequencies, it’s versatile for different types of jobs. Whether you’re drilling a shallow line for a residential utility or a deeper crossing under a highway, you can configure the F2 system appropriately – choose a short-range sonde for tight spots, or an extended-range sonde for long pushes, switch frequencies as needed, etc. This adaptability means one F2 system can handle a wide spectrum of HDD projects, providing great value to a drilling company.
5. Cost-Effective Ownership: Compared to higher-end locating systems, the F2 hits a sweet spot in terms of cost vs. capability. It delivers nearly all the functionality needed for common drilling jobs at a lower price point than the top-of-the-line models. Furthermore, the availability of quality used F2 equipment on the market makes it even more cost-effective. Companies can purchase refurbished F2 locators and transmitters that are fully tested and come with warranty protection – getting like-new performance for a fraction of the cost of new. This can significantly lower the barrier to entry for smaller contractors or expand the capabilities of larger outfits without a big capital expenditure.
6. Training and Support: Because the F2 is popular and widely used, there is a wealth of training material, user communities, and support available. DCI (the manufacturer) provides manuals and how-to videos, and many experienced operators are familiar with the F2. New crew members can be trained on the system relatively quickly, and if any issues arise, it’s easy to find help or spare parts. This ecosystem of support adds to the F2’s appeal as a reliable long-term investment for an HDD crew.

Acquiring a DigiTrak F2: New vs. Used

When considering adding a DigiTrak F2 locator system to your equipment fleet, you have the choice of buying new or looking at the used market. Each route has its advantages:

• New Equipment: Purchasing a new F2 (or the latest Falcon F2+ model) directly from a dealer ensures you get the latest firmware, a full factory warranty, and that fresh-out-of-the-box assurance. You’ll have the backing of the manufacturer’s support from day one. However, new systems come at a premium price. For some small businesses or one-off projects, the cost might be a limiting factor.
• Used/Refurbished Equipment: The HDD industry has a healthy market for used DigiTrak locators and sondes. Reputable resellers (such as UCG Underground and others) offer used DigiTrak F2 locators, transmitters, remote displays, batteries, and chargers for sale, often fully inspected, tested, and backed by their own warranties. Going the used route can save a significant amount of money while still delivering reliable performance – especially if the equipment has been professionally refurbished. As highlighted earlier, an F2 system’s value is in its proven technology; a used unit from a few years ago can perform just as well as a new one on most jobs. Just be sure to buy from a trusted source that can verify the condition and offer after-sale support.

One of the major benefits of buying used through a company like UCG Underground is the extra services that may come with it. For example, UCG offers a 100-day warranty on used F2 equipment and aims to take the stress out of buying used. They also provide rapid fulfillment options – with next-day shipping within the USA (to minimize your downtime if you need a replacement urgently) and even same-day in-store pickup if you are local. Additionally, they can ship worldwide, coordinating with freight forwarders to get the equipment to international job sites efficiently. This level of service ensures that even if you’re buying second-hand, you’re not left on your own if something goes wrong or if you need quick delivery.

Another attractive option is trading in old equipment. If you already have an older locator (or even another F2) and want to upgrade or simply cash out, some dealers will take trade-ins. UCG, for instance, advertises that they offer competitive trade-in deals that local dealers can’t match. This could mean you get credit towards an F2 by trading in older DigiTrak models or even other brands of locating equipment, making the upgrade path more affordable. It’s worth checking with such specialized resellers because they have a pulse on the used market and can often offer better value than general equipment dealers.
