Three Topcon SLAM scanners, three different jobs. The spec sheets won’t tell you which one you need, so here’s the short version.
CR-S2 is the lightest at 2.87 lbs, one-handed, 200,000 points per second out to 230 feet. It’s built for tight spaces. Basements, mechanical rooms, parking structures, interior progress monitoring. The places where the GPS-dependent tools quit.
CR-S1 steps up to 320,000 points per second and 394 feet, with three 12MP panoramic cameras for better colorized data. At 4.85 lbs it’s still a one-hand carry, and it mounts to a backpack or pole when you want it. Best for large open sites, infrastructure work, and topo.
CR-M1 is the continuous-capture option. 640,000 points per second, 394 feet, full 360 by 360 coverage, mounted to a backpack, pole, or vehicle. Built for multi-floor buildings, urban mapping, and covering a lot of ground in one pass.
All three track position through SLAM, which means they keep working underground and indoors where satellite signal doesn’t reach.
The honest answer is that most crews only need one of these, and it’s usually not the most expensive one. Tell us what you’re capturing and we’ll point you to the right tool, even if it isn’t the one we’d rather sell.
