The Slamtec Mapper has two models with a detection range of 20m and 40m. It can easily map for home scenes or commercial, light industrial scenes. In the handheld mode, the built-in 9 degrees freedom inertial navigation system of the M1M1 can eliminate the bumps and shake caused by walking and exert super high map construction performance.
