Review: Faro Focus S350 — a powerful tool for accurate measurement

1. Key features of Faro Focus S350

• Range and accuracy. The scanner works at distances up to 350 m with an accuracy of about ±1 mm, making it suitable for surveying construction sites, industrial facilities and façades.

• Speed. Acquisition speed of up to about 976,000 points per second allows large areas to be covered quickly.

• Mobility. Weighing around 4.2 kg with a 4.5‑hour battery life, the S350 is convenient for field work. The enlarged touchscreen simplifies operation.

• Weather protection. With an IP54 rating and operating temperature range from −20 °C to +50 °C, the device can be used in both heat and frost.

• On‑site functions. Built‑in auto‑calibration and compensation enable accuracy checks on site. “Scan Group” and “Retake Photo” functions allow specific areas to be rescanned without repeating the entire job.

2. Illustrative use cases

A. Construction and BIM projects

Companies use the S350 to generate point clouds of existing buildings for creating Building Information Models. For example, during renovation of warehouse complexes, the scanner provides accurate geometry of walls, columns and slabs, helping designers avoid collisions.

B. Industrial sites

In oil and gas and energy industries, the S350 is used to measure pipelines and equipment. Its wide temperature range and dust protection allow work in harsh environments such as high‑humidity or dusty workshops.

C. Forensic and accident reconstruction

Thanks to its high detail, the scanner is used to document accident or crime scenes. Police and forensic experts can build 3D models of a site to analyse trajectories, distances and spatial relationships.

3. User feedback: what people like and dislike

Based on numerous open reviews on forums and communities, here is what professionals think about the Faro Focus S‑series.

Likes:

• Compactness and autonomy. Users appreciate that the scanner is easy to carry and deploy by one operator. The battery lasts 4–5 hours, sufficient for most shifts.

• Clean data. Compared with the previous X‑series, scans have less noise and fewer artefacts, especially at long distances, reducing filtering and processing time.

• Performance in tough conditions. The S350 withstands rain, dust and temperature fluctuations. Some mention being able to scan in snow or high wind.

• On‑site compensation. Engineers value the ability to verify calibration on site, saving time and service costs.

• Extended range. A 350‑m range allows large objects to be covered without moving the tripod, reducing the number of set‑ups and accelerating surveys.

Dislikes:

• SCENE software. The most frequent complaint is about SCENE’s stability: it can freeze during registration, process large projects slowly and requires powerful computers. Some professionals even consider switching to alternative platforms or brands because of post‑processing issues.

• License costs. Software modules and updates are quite expensive. Many dislike paying separately for additional features.

• Speed compared to competitors. Users who have worked with the Leica RTC360 note that the Faro S350 is slower in capturing and auto‑registration. For large projects this can be critical.

• Point‑cloud registration problems. Without automatic target‑based alignment, the scanner doesn’t always connect stations properly when there are many scans.

• Firmware limitations. Some mention that scanning range is limited by firmware and cannot be unlocked, even though the hardware might support greater distances.

4. Summary

The Faro Focus S350 is a versatile scanner combining portability, long range and high accuracy. Builders, industrial operators and forensic experts choose it for its ability to work in challenging conditions and deliver clean data. The biggest pain point for many users is the SCENE software, which can be complex and unstable. Anyone considering the S350 should factor in software costs and compare its speed with competitors such as Leica or Trimble.

In conclusion, the Focus S350 is a solid choice for those who value range and hardware reliability and are willing to invest in the Faro ecosystem while accepting some compromises in post‑processing convenience.
