Johnson Level & Tool 40-6705 One-Sided Rotary Laser Detector w/Clamp

This laser detector is ideal for using red beam rotary lasers outdoors, in high ambient light conditions or whenever the human eye cannot see the laser beam by quickly and accurately locating the laser signals. Accuracy is never a problem thanks to the audible and ultra bright LED indicators that allow for precise leveling. And the included clamp easily attaches the laser detector to grade rods for determining differences in elevation.
