Product details:

AdirPro's LD-8 laser detector is compatible with red rotary lasers in all lighting conditions, which allows you to use it indoors or outdoors. The AdirPro LD-8 detector is robust with its hard plastic housing and rubber casing. It has a dual display and a built-in bubble level for convenience. The backlight to the liquid crystal display can be adjusted with the touch of a button. The same goes for the volume. In addition to the on/off button, there is an automatic shut-off feature that will power down the device after about ten minutes of being idle (so as to extend your batteries' lifetime). With two new AA batteries you can get approximately 40 working hours. The interface is user-friendly and smart in its simple design. The readouts are clear and accurate. The LD-8 laser detector comes with a compatible rod mounting bracket. The threading of both the screw on the bracket and the nut in the unit have 1/4" threading. (2) AA batteries included.
