Quickly and accurately locating laser signals even when the beam is invisible to the eye, AdirPro 's LD-8 Laser Detector is compatible with all red rotary lasers in any lighting condition. This allows for use both indoors or out, including installing ceiling tiles, aligning shelves, installing receptacles for power in a home, trenching, laying pipe, setting concrete forms and leveling driveways. Laser receivers can shorten the amount of time needed to find the beam and get on level. Easy to use, the AdirPro features a magnetic strip that allows you to affix the receiver onto any metal surface. The interface is user-friendly, smart in its simple design and the readouts are clear and accurate. Built tough to last, the detector is robust with its hard plastic housing and rubber casing to provide long-term durability and use, as well as protection against weather conditions. For convenience, it boasts a dual-sided LCD display that shows the elevation, grade sensitivity, audio and battery status. A built-in bubble level provides an extra measure of leveling accuracy, while the accuracy mode allows you to switch between ultra fine and very coarse. Both the volume and backlight to the liquid crystal display can be adjusted with the simple touch of a button. In addition to the on/off button, there is an automatic shut-off feature that will power down the device after about 10 minutes of being idle. The LD-8 laser detector comes complete with a compatible rod mounting bracket. Secure the receiver to the clamp with the ¼ thread screw and then clamp the receiver to a grade rod or wooden pole. The non-expanding bolt adjustment system easily adjusts with a screwing motion and ridged edges give extra friction to secure the clamp to the rod.
