Underground Magnetics MAG X Geo: GPS with RTK Correction for HDD

Horizontal directional drilling has always depended on accuracy, communication, and good field decisions. Every bore requires the crew to understand where the drill head is, where it is going, and what is around it. For years, locating systems helped crews track depth, pitch, roll, and direction, but the documentation side of the job often required extra steps. The Underground Magnetics Mag X GEO brings locating and jobsite mapping closer together by combining HDD tracking data with GPS and RTK correction in one field-focused system.

The biggest change is how bore data is collected. Instead of relying only on handwritten notes, separate GPS tools, or after-the-fact reporting, MAG X Geo allows crews to log important information as the bore is happening. The system is designed to record rod-by-rod data such as pitch, depth, and GPS position, helping create a clearer record of the bore path from start to finish. Underground Magnetics lists built-in data logging, integrated GPS + RTK, and rod-by-rod metrics as key parts of the MAG X Geo system.

GPS by itself has been useful on jobsites for a long time, but RTK correction takes it to another level. RTK, or Real-Time Kinematic correction, improves GPS accuracy by using correction data to reduce positioning errors. For HDD contractors, that means the recorded bore path can be much more accurate than standard GPS alone. Underground Magnetics states that MAG X Geo uses RTK-enabled GPS with 1–3 cm accuracy, which is a major advantage for crews that need reliable documentation.

This matters because today’s projects demand more than simply completing the bore. Contractors are often expected to provide clear records, show where utilities were crossed, document depth, and deliver information that can be reviewed later. With MAG X Geo, crews can mark utility crossings as they expose them and include details such as utility type, GPS location, and depth. That kind of information helps turn the locating system into a stronger documentation tool, not just a tracking tool.

Another important benefit is real-time visibility. MAG X Geo offers multiple ways to view progress, including map, chart, and rod table views, giving both the locator and drill operator a better understanding of the bore. Instead of looking at the job from only one angle, the crew can see the overhead path, side profile, and recorded rod information. This helps reduce confusion, especially on longer or more complex shots where small changes can matter.

For drill operators, better information can lead to better decisions. Tools like GPS Dropline, Pitch Guide, and Bore-To steering are designed to help guide the bore path and keep the crew aligned with the intended target. When the locator, display, and logged GPS data work together, the crew can respond faster and stay more organized. That can make a real difference when working around existing utilities, road crossings, tight easements, or crowded urban infrastructure.

MAG X Geo also helps reduce the amount of cleanup after the bore is finished. On many jobs, crews have to gather notes, compare measurements, organize GPS points, and build a report after the work is done. By recording data during the bore, MAG Geo can simplify that process and help create a more complete job record. Trenchless Technology noted that the system lets operators log pitch, depth, and GPS coordinates on a rod-by-rod basis from a single device.

The industry is moving toward better digital records because owners, engineers, and utility companies want more transparency. A completed bore is no longer judged only by whether the pipe was installed successfully. The quality of the documentation is becoming part of the job. GPS with RTK correction helps HDD contractors provide cleaner, more accurate records that can support as-builts, future maintenance, utility mapping, and project closeout.

This technology also benefits the crew in the field. When information is easier to see, easier to record, and easier to share, the team can spend less time managing paperwork and more time focusing on the bore. MAG X Geo’s 7-inch color touchscreen and field-ready controls are built to make the system practical on real jobsites, not just impressive on a spec sheet. Dig Different also described the system as offering survey-grade accuracy locating and highlighted its touchscreen and at-a-glance data layout.

Underground Magnetics MAG X Geo shows where HDD locating is headed: more accurate, more connected, and more data-driven. By combining proven locating tools with GPS and RTK correction, it helps contractors track the bore, document the job, and deliver stronger information to customers. As the industry continues to demand better records and tighter accuracy, systems like MAG Geo are helping crews bore smarter, reduce uncertainty, and bring modern mapping technology directly into the HDD workflow.
