Precision, durability, and a convenient design make the DEWALT DW0772 digital laser detector a versatile addition to your tool kit. This unit is compatible with all rotary lasers. The detector works regardless of whether the beam is visible or invisible or if you are working indoors, outdoors, or in bright light. This detector achieves accuracy within 1/25-inch (1mm), and it extends the working range of most lasers to an astounding 1000 feet for increased versatility. Other convenient features include three volume settings, a completely waterproof housing, and a dual-LCD design that lets you read results from both sides of the detector, a feature that’s especially useful when you’re standing behind a grade rod. The included heavy-duty clamp is built to stand up to the rigors of the job site, and it makes it easy to mount the detector to a rod or other target point.
