It can be used on its own or in conjunction with a RIDGID LM-400 Laser Distance Meter. The app will connect to your LM-400 via Bluetooth® and wirelessly receive the exact measurements from the device. RIDGIDSketch works in both drawing mode and photo overlay mode allowing you to develop precise room plans or annotate measurements within a photo.
