Johnson Level & Tool Pro 40-6700 One-Sided Laser Detector with Clamp

This laser detector pairs with red beam rotary lasers outdoors, in high ambient light conditions or whenever the human eye cannot see the laser beam. It quickly and accurately locates the laser signal for you. With a back-lit LCD display for easy reading and fine/coarse detection settings, the detector displays the information you need to get your leveling job done quickly and easily. Accuracy is never a problem thanks to the audible and visual indicators that allow for precise leveling. And the included clamp easily attaches the laser detector to grade rods for determining differences in elevation.
