Smart Planner is an adapter for the HOZO M-Cube measuring device. It extends the device, facilitates work, and provides new, more advanced capabilities. Its main purpose is to enhance accuracy and convenience when working with the laser tool. Joystick control allows for achieving highly precise measurements. It implements two useful functions: automatic contour closure and auto-leveling. It is equally suitable for indoor space measurements. There is also a One-Tap button on the body, necessary for precise and smooth work with angles and edges. The adapter easily attaches to and detaches from the main measuring device using a reliable locking system.
