Leica BLK360 Gen 2 vs FARO Focus M70: A Field-by-Field Comparison for Surveyors

I have run both scanners on the same project — a mixed-use building survey combining interior documentation and exterior facade work — and the experience was instructive in ways a spec-sheet comparison never is. The Leica BLK360 Gen 2 and the FARO Focus M70 occupy overlapping price brackets and are routinely shortlisted against each other, yet they represent meaningfully different philosophies about what a field laser scanner should be.

Instruments at a Glance

The Leica BLK360 Gen 2, released in 2022, is the second generation of Leica’s compact panoramic scanner. It pairs a 360° laser scanner with a spherical imaging system and is designed for rapid deployment: no external controller required, operation via iPad through the Leica Cyclone FIELD 360 app. The Gen 2 brought significant upgrades over the original — most notably a jump from 360,000 to 680,000 points per second and improved range performance.

The FARO Focus M70, introduced in 2020 as part of the Focus S/M/X refresh, targets the mid-range professional segment. It offers a 70-metre maximum range, a built-in colour camera, onboard touchscreen operation, and native Wi-Fi for data transfer. FARO positions it as a versatile workhorse for construction, BIM documentation, and facility management — usable without a laptop or tablet on site.

Technical Specifications Comparison

Range and Accuracy: What the Numbers Mean in Practice

On paper the FARO Focus M70 wins the range contest at 70 m versus the BLK360 Gen 2’s 45 m. In practice, whether that difference matters depends entirely on your typical site. For indoor BIM documentation — office floors, corridors, plant rooms, stairwells — 45 m is rarely a constraint. For open exterior work, large warehouse interiors, or tunnel surveys, the M70’s additional range reduces the number of scan positions and accelerates registration.

On 3D point accuracy both instruments are close: ±1.5 mm for the BLK360 Gen 2 and ±1.0 mm for the Focus M70. In most construction and facility management workflows, this difference is not decision-relevant — registration errors and surface noise in the combined point cloud will dominate long before instrument accuracy becomes the limiting factor. Where it does matter is in as-built documentation for tight-tolerance fabrication or heritage recording, where the M70’s edge is real.

Weight, Form Factor, and Field Ergonomics

This is where the two scanners diverge most sharply. The BLK360 Gen 2 weighs 0.99 kg — light enough to carry in a shoulder bag alongside an iPad. Setup takes under a minute: place on tripod, open the app, tap scan. For multi-storey interior surveys with 30–50 scan positions per floor, this workflow translates into a measurable productivity advantage.

The FARO Focus M70 weighs 4.2 kg and requires attaching a battery pack before deployment. It is not a heavy scanner by historical standards, but compared to the BLK360 Gen 2 it is a different category of physical effort over a long field day. That said, the M70’s onboard touchscreen means you are not dependent on a tablet: the scanner can be configured, started, and monitored directly on the device. For solo operators in spaces where handling two devices is awkward, this is a genuine advantage.

Registration Workflow and Software Ecosystem

Leica’s ecosystem centres on Cyclone FIELD 360 for field capture and Cyclone REGISTER 360 (or the more powerful Cyclone 3DR) for office registration. The workflow is cloud-connected by design: scans upload automatically, registration happens in the cloud, and you can review preliminary results before leaving site. For teams working across multiple projects, this reduces turnaround time significantly.

FARO’s native software is FARO SCENE. It is a mature, capable platform for registration, point cloud cleaning, and export — and it runs entirely offline, which matters in environments where uploading gigabytes of scan data via a cellular connection is impractical. SCENE’s target-based and cloud-to-cloud registration is well-regarded, and the software supports a broad range of downstream formats including RCP, E57, LAS, and PTX.

Both ecosystems connect to third-party platforms: Autodesk ReCap, Trimble RealWorks, and others. If your office already uses one of these for processing, the choice of scanner hardware matters less than it used to. The more important question is whether your team will be using the native software consistently, and which workflow your operators find more efficient.

When to Choose Which Scanner

There is no universal answer, but there are clear patterns.

Choose the Leica BLK360 Gen 2 if:

• Your primary workload is interior building documentation, BIM capture, or heritage recording in confined spaces.
• Speed of deployment and minimal setup friction matter more than maximum range.
• You work in a cloud-connected workflow and want preliminary registration results before leaving site.
• Portability is a genuine constraint — you regularly carry equipment up stairs, through tight access, or on public transport.
• You are integrating with Leica’s wider ecosystem (Cyclone, BLK2GO, Leica RTC360).

Choose the FARO Focus M70 if:

• Your projects include large open interiors, exterior facades, or environments where 45 m range is insufficient.
• You need longer battery autonomy without battery rotation during a field session.
• You prefer onboard operation without dependency on a tablet or mobile device.
• Your office processing workflow is built around FARO SCENE or an offline pipeline.
• Budget is a consideration and you are open to a refurbished unit — the M70 has a strong used market with readily available service history.

Buying Used: What to Verify

Both scanners have an active secondary market. The BLK360 Gen 2 is relatively recent (2022), so used units are typically lightly worked. The FARO Focus M70 has been on the market longer, and used examples vary considerably in condition.

Before purchasing a used unit of either scanner, verify the following:

1. Request the date and results of the most recent factory calibration or certified service check. Laser scanners require periodic calibration — a certificate older than 12–18 months should prompt a price negotiation or a pre-purchase independent inspection.
2. Check the scan count (number of scans recorded) if the vendor can provide it. High scan counts do not automatically indicate poor condition, but they inform maintenance history.
3. Inspect the scanner window — the rotating mirror enclosure — for scratches or contamination. This is the most vulnerable optical component and the most expensive to replace.
4. Test the imaging system: request a sample scan with colour imagery and verify that the camera registration to the point cloud is correct.
5. Confirm that all original accessories are present: battery, charger, carry case, and calibration artefacts where applicable. Replacing a missing FARO battery pack alone can add €300–500 to the effective purchase price.

Conclusion

The Leica BLK360 Gen 2 and the FARO Focus M70 are both credible professional tools with well-established track records in the field. The BLK360 Gen 2 is the faster, lighter, more portable option — built for rapid multi-position interior workflows with a tightly integrated cloud pipeline. The Focus M70 offers greater range, longer battery life, and a mature offline processing ecosystem that suits larger sites and teams with an established FARO SCENE workflow.

Neither scanner is objectively superior. The right choice is the one that matches your specific project mix, team size, and processing infrastructure. If you are evaluating used units of either — a sensible approach given current pricing on the secondary market — independent quality inspection before purchase is the single most important step you can take to protect the investment.
