Option A Xgrids

Xgrids Lixel L2 Pro

Handheld SLAM Scanner with Native Gaussian Splatting

The Xgrids Lixel L2 Pro is a 32-channel handheld SLAM scanner capturing 640,000 points/sec with <1-2cm relative accuracy, dual 48MP cameras, and native Gaussian Splatting output via Lixel CyberColor (LCC) software. It carries the only GS-to-BIM Revit plugin on the market plus SDKs for Unity, Unreal Engine, and WebGL, so a single walk-through can produce both an engineering point cloud and a photorealistic splat scene.

Pros

Native Gaussian Splatting output via Lixel CyberColor (LCC) software
Only GS-to-BIM Revit plugin on the market (LCC for Revit)
SDKs for Unity, Unreal Engine, and WebGL — game engine ready
High point density (up to 1M pts/m² at 1mm spacing) without post-processing
Long reach for a handheld — 120m standard, up to 300m on select 32-channel models
Lightweight (1.7kg) with a 1 TB onboard SSD and IP54 sealing

Cons

Proprietary GS format (LCC) — not standard PLY
Processing: roughly 1 hour per 3-minute scan in LCC
Higher price point (~$15,000-$25,000 system)
Requires the LCC software ecosystem for GS features
Centimeter-class accuracy — well short of the VLX 3 millimeter specification

Option B NavVis

NavVis VLX 3

Flagship Wearable SLAM Scanner for Large Facilities

The NavVis VLX 3 is the flagship wearable scanner, combining dual 32-layer LiDAR sensors for 1,280,000 points/sec (2 × 640,000, datasheet v2409) with LiDAR SLAM and four 20MP cameras. NavVis publishes 5mm local accuracy, 1 sigma, in a dedicated 500 m² test environment, with physical control-point support to constrain absolute accuracy. It is built for rapid documentation of large, multi-floor facilities, with output processed in NavVis IVION for digital twin delivery.

Pros

Continuous walk-through capture with no tripod setups
Handles stairs and elevators
Real-time visual feedback on data coverage
IVION cloud processing included
Millimeter-class local accuracy — 5 mm, 1 sigma, in NavVis' 500 m² test environment
Digital twin ready output

Cons

Requires training
IP42 only — limited protection against water
8.5 kg worn on the body versus 1.7 kg handheld
50 m range ceiling limits long-shot capture of tall or distant surfaces

Best For

Large facilities (100,000+ sqft)Multi-floor buildingsRapid documentation deadlinesDigital twin creation

Our Expert Verdict

Depends on Your Needs

This is an accuracy-and-throughput system versus a visualization-and-BIM system. The NavVis VLX 3 is the stronger measurement instrument by a wide margin — 5mm local accuracy (1 sigma, NavVis' 500 m² test environment) and 1,280,000 pts/sec across its dual 32-layer sensors, captured continuously on foot. The Xgrids Lixel L2 Pro trades that precision for centimeter-class accuracy in a 1.7kg handheld with far longer reach (up to 300m on select 32-channel models) and, uniquely, native Gaussian Splatting through LCC plus the only GS-to-BIM Revit plugin available. If the deliverable is a measurable digital twin of a large facility, the VLX 3 leads. If the deliverable includes photorealistic splat scenes or game-engine assets, the L2 Pro does something the VLX 3 does not.

Choose Xgrids Lixel L2 Pro if...

Choose the Xgrids Lixel L2 Pro when the deliverable includes Gaussian Splatting — photorealistic walkthroughs, Unity/Unreal/WebGL assets, or GS data that has to land inside Revit through the LCC plugin — and centimeter-class geometry is acceptable.

Choose NavVis VLX 3 if...

Choose the NavVis VLX 3 when accuracy and coverage rate drive the project: large multi-floor facilities, deadline-driven as-built documentation, and digital twins where 5mm-class local accuracy is the requirement.

Frequently Asked Questions

Which scanner is more accurate?

The NavVis VLX 3. It is specified at 5mm local accuracy (1 sigma, 500 m² test environment) with physical control-point support to constrain absolute accuracy — NavVis publishes no figure for the result with control points. The Xgrids Lixel L2 Pro is specified at <1-2cm relative and <3cm absolute — a 2-4× difference that is decisive for measurement-critical as-built work.

Which captures more area per day?

The VLX 3. Its dual 32-layer sensors capture 1,280,000 points per second continuously while walking, and it handles stairs and elevators. The L2 Pro captures 640,000 pts/sec in its 32-channel configuration (320,000 in the 16-channel model). Neither manufacturer publishes an area-per-day figure.

Which one produces Gaussian Splatting?

Only the Xgrids Lixel L2 Pro. Its Lixel CyberColor (LCC) software outputs Gaussian Splatting natively, and Xgrids ships the only GS-to-BIM Revit plugin on the market along with SDKs for Unity, Unreal Engine, and WebGL. NavVis VLX 3 data is processed in NavVis IVION for point cloud and digital twin delivery.

How different are they to carry?

Substantially. The L2 Pro is a 1.7kg handheld unit (without battery). The VLX 3 is an 8.5 kg wearable system. Over a long capture day that difference shapes operator fatigue and how tight a space you can work in.

Which has the longer range?

The L2 Pro. It covers 0.5-120m as standard, with select 32-channel models reaching up to 300m. The VLX 3 is rated at up to 50m operational range, which is ample for interiors but limits capture of tall bays, distant facades, or open exterior areas.

Are either of these suited to outdoor work?

Both are primarily indoor and building-scale tools. NavVis rates the VLX 3 IP42 for indoor and outdoor use, which offers little protection against rain; the L2 Pro is described as indoor and building-scale focused rather than a solution for large outdoor areas, though it carries an IP54 rating and the longer range of the two. Large exterior sites are better served by drone-based capture.
