It was somewhere outside Barstow when Will wrote:

anyone have any experience with the Black & Decker 360 deg. Auto Laser
Level? Does it cast a level plane, or does it have a rotating head?

If it's 360°, it's a rotating head. If it's a cross, it's line
generators.

I wouldn't touch any of the current crop (the red and black stuff) of
B&D products.
