Which is better: NavVis VLX 3 or Leica BLK2GO?

The NavVis VLX 3 and Leica BLK2GO are both mobile SLAM scanners, but they target different project scales and quality requirements.

NavVis VLX 3:

• Point rate: 1.28 million points per second (2 × 640,000, 2x32-layer LiDAR, NavVis datasheet v2409)
• Accuracy: 5 mm local accuracy (1 sigma) in NavVis' dedicated 500 m² test environment; absolute accuracy depends on the size of the environment and is controlled with survey control points
• Weight: 8.5 kg (wearable backpack)
• Cameras: 4 x 20MP fisheye (360° coverage)
• Battery: 1.5 hours per set of two hot-swappable batteries
• Coverage: 200,000-300,000 sqft/day
• Processing: NavVis IVION platform (digital twin)
• Best for: Large facilities, warehouses, hospitals, campuses

Leica BLK2GO:

• Point rate: 420,000 points per second
• Accuracy: 6–15 mm relative accuracy (Leica's currently published shop spec sheet, 2025-09). Leica's 05/2021 BLK2GO datasheet instead states range noise ±3 mm and ±10 mm indoors — both sheets are live, so we quote both rather than pick one.
• Weight: 0.775 kg including battery (handheld)
• Cameras: 12 Mpixel high-resolution camera plus a 3-camera 4.8 Mpixel panoramic vision system
• Battery: 45–50 minutes
• Processing: Cyclone REGISTER 360
• Best for: Quick walkthroughs, small-medium spaces, AEC documentation

Key Differences:

1. Data density: VLX 3 captures roughly 3x more points per second (1.28M vs 420K) — denser point clouds for detailed documentation
2. Accuracy: NavVis publishes 5 mm local accuracy for the VLX 3; Leica publishes 6–15 mm relative for the BLK2GO — significant for engineering applications
3. Coverage speed: the VLX 3's higher data rate and continuous operation cover more area per session
4. Imagery quality: VLX 3's 4x20MP cameras produce higher-resolution panoramic imagery for digital twins
5. Form factor: BLK2GO is lighter and more portable; VLX 3 is wearable but heavier

THE FUTURE 3D Recommendation: For large facility documentation (warehouses, manufacturing, healthcare), the VLX 3 is the clear choice — its speed and accuracy justify the form factor. For quick walkthrough documentation or tight spaces, we deploy the NavVis MLX (our handheld complement to the VLX 3) which offers better accuracy than the BLK2GO at similar portability.
