Tech Data Sheets
Unlike stationary or bulkier systems, the Topcon CR-S2 Portable Handheld SLAM 3D Scanner is a truly portable handheld scanner with fusion-SLAM technology. It captures data while you walk, delivers real-time colorized point clouds and meshes, and maintains centimeter-level accuracy even indoors, in dense forests, or GNSS-denied areas.
Real-time scan registration and processing occurs in the field using the MAGNET Flow app, with later office processing via MAGNET Bridge and cloud collaboration through Topcon Collage Web. The system supports seamless export to standard point cloud formats (LAS, e57, etc.), meshes, and more for integration with your preferred software.
Key Features

Common Questions About the Topcon CR-S2
What is the Topcon CR-S2?
The CR-S2 is a portable, handheld SLAM-based 3D scanner built for fast mobile capture in tight or hard-to-access spaces.
How does the CR-S2 track its position without a fixed setup?
It uses multi-sensor fusion — MLF-SLAM, VSLAM, and RTK-SLAM — combining LiDAR, visual tracking, and inertial data to map its position as you move, rather than relying on a stationary setup or GPS alone.
How accurate is the CR-S2?
About 3/4 in relative accuracy and under 1 13/16” absolute accuracy. With RTK, horizontal accuracy is 5/16" + 1 ppm and vertical is 9/16" + 1 ppm.
What's the range and scan speed?
Up to 230 ft (230 ft) at 80–90% reflectivity, capturing up to 200,000 points per second.
How much does the CR-S2 weigh?
2.87 lbs (2.86 lbs) — the lightest of Topcon's portable SLAM scanners, which is what makes it well-suited to tight interior spaces and long walkthroughs.
What cameras does the CR-S2 use for colorization?
Two 12MP panoramic cameras plus two 1.3MP VSLAM cameras.
What's the CR-S2 best used for?
Tight spaces, progress monitoring, stockpile volume calculations, and combined indoor/outdoor construction site mapping.
What software does the CR-S2 use?
MAGNET Flow for field capture, MAGNET Bridge for processing, with data publishable to Topcon Collage Web for cloud collaboration and review.
How is the CR-S2 different from the CR-S1?
The CR-S2 is lighter (2.87 lbs vs. 4.85 lbs) with a shorter range (230 ft vs. 394 ft) and a lower relative-accuracy spec (13/16" vs. 3/16") — it trades range and precision for portability, making it better for tight or indoor spaces where the CR-S1's longer range isn't needed.
Can the CR-S2 be used indoors and in GNSS-denied areas?
Yes — its SLAM-based positioning doesn't depend on GNSS, so it works indoors, underground, or anywhere satellite signal is unreliable.
What format is the point cloud data exported in?
LAS, e75, and other common formats compatible with standard CAD, BIM, and GIS software.
Is the CR-S2 a good fit for a smaller contractor doing a mix of project sizes?
Its combination of light weight, indoor capability, and stockpile/volume support makes it a versatile all-around choice — the main trade-off is its shorter 230 ft range and lower relative accuracy compared to the CR-S1, which matters more on large open sites.
