Which Should You Buy?
Scenario 1: Growing Surveying Firm with Mixed Projects
Best Choice: Spectra Focus 30
If you handle a mix of small to medium projects and want to grow without massive capital expense, the Focus 30 delivers excellent performance at a better price point. You'll have the speed and accuracy needed for most jobs, and can add a second unit later if demand increases.
Scenario 2: Large-Scale BIM and Volumetric Projects
Best Choice: Spectra Focus 35
For firms handling complex BIM models, large industrial as-builts, or volumetric site measurements, the Focus 35's superior range (120m), point speed, and accuracy justify the investment. Faster scanning reduces fieldwork time and improves project profitability on high-value contracts.
Scenario 3: Budget-Conscious New Entrant to 3D Scanning
Best Choice: Spectra Focus 30
Starting your first 3D scanning service? The Focus 30 offers manageable pricing while still delivering professional-grade results. The lower investment reduces risk as you build your scanning expertise and client base.
Scenario 4: High-Volume Daily Scanning Operations
Best Choice: Spectra Focus 35
If your team scans multiple sites per day or requires the absolute best in speed and range, the Focus 35's 976k points/second capability pays for itself through improved field efficiency and faster project delivery times.
Frequently Asked Questions
The Focus 35 excels in scanning speed (976k vs 614k points/sec), range (120m vs 90m), accuracy (±3mm vs ±4mm), and battery life (8 vs 7 hours). The Focus 30 offers strong performance at a significantly lower price point—ideal for firms that don't need maximum throughput.
Yes, the Focus 30 can scan up to 90 meters, which covers most construction sites effectively. For larger areas or very distant objects, you may need multiple setups, which adds minimal time. The Focus 35's 120-meter range is better for sprawling industrial sites or open-area projects.
Both models work well indoors. The Focus 30's slightly shorter range is less of a limitation in confined spaces, making it very practical for interior documentation. The Focus 35 adds flexibility for larger interior spaces like warehouses or atriums.
The Focus 35 delivers ±3mm accuracy at 10 meters, while the Focus 30 provides ±4mm. In practical terms, both exceed industry standards for most surveying and construction work. The 1mm difference matters most on precision-critical projects like interior renovations or mechanical plant documentation.
Both models integrate with Spectra Office Suite and industry-standard CAD/BIM software. The Focus 35 includes advanced software packages; the Focus 30 uses a streamlined version that covers most needs. Upgrading software is straightforward on both platforms.
