The KAPRO detector is designed for KAPRO Green Line lasers. It is used with pulsed laser tools for extended ranges and also for detecting laser beams in bright light or hard-to-see situations. The detector provides a self-leveling range of ±4°. It is equipped with bright, highly visible indicator lights and a visual and audible warning. The detector switches off automatically and requires a 9V battery to operate. You will be pleased with the built-in spirit level and holder for fixed objects.
