The Leica BLK3D is a ground-breaking measurement instrument. Its integrated stereo measurement camera system generates smart images which allow for instant in-picture measurements. Its design follows clearly defined lines which creates an intuitive user experience. It is robust, powerful and compact. This makes it the ideal hand-held tool for challenging environments, such as construction sites. The vision was to develop a tool which creates a symbiosis of robustness, ergonomic and visually appealing design. As a result, the BLK3D is fit for purpose, handles very well and impresses with high-quality materials.
