Modern PRO models do not require magnetic calibration; they are activated with a simple back-and-forth movement of the rod.

Yes, by using IMU instead of an electronic compass, you can measure near transformers or metal structures without error.

The SDi PRO includes a laser on the bottom designed to measure inaccessible points where you cannot place the rod tip (such as the bottom of a deep trench, points under a vehicle, or behind a fence). When combined with the IMU sensor, you can achieve an accuracy of 1 to 3 centimeters over short distances (up to 10-15 meters). It is a "maneuvering" tool that saves a lot of time in the field by avoiding station jumps or indirect methods.

The main difference of the STEC SDi Pro lies in its performance improvements for more demanding terrain work. Compared to the standard SDi, the SDi Pro offers greater laser range, better accuracy in laser-assisted measurements, improved cameras, and an optimized IMU system. This translates into a more complete work experience: it allows capturing difficult points with greater confidence, improving visualization in the field, and maintaining more stable measurement even in conditions where it is not always possible to position the rod perfectly vertical. Simply put: the SDi Pro is designed for those looking for a more powerful, accurate version prepared for complex terrain, especially when the laser, cameras, and tilt are key parts of the workflow.

Yes. The STEC SDi Pro can be connected with equipment from other brands, as long as the communication flow is compatible. For this type of integration, the TrimTalk protocol can be used, which allows communication between compatible GNSS equipment. This is especially useful for companies that already have bases, rovers, or other GNSS equipment in the field and seek to integrate the SDi Pro into an existing ecosystem. Before implementing it, it is advisable to validate the specific compatibility between equipment, protocols, frequencies, and radio configuration to ensure a stable connection in the field.

Yes. The STEC SDi Pro can connect to CORS networks via NTRIP, as long as the user has the corresponding access credentials. This allows working with real-time corrections without necessarily relying on a base station on the ground, provided there is network coverage, internet connection, and active access to the CORS service. In practice, you only need to correctly configure the connection data, such as server, port, user, password, and mountpoint. With this, the equipment can receive corrections and work with greater precision in surveys, stakeouts, and GNSS measurements.
