Electronic levelling tool swaps a bubble for LEDs

Bubble-type levels have been around for hundreds of years, and even digital models with LCD numerical displays aren't exactly new. A group of Montreal-based entrepreneurs have come up with something a little different, though, in the form of the LED-packin' LumiLevel. Touted as being the world's most accurate level, the tool features a strip of 25 LEDs that illuminate to one side or the other, indicating its vertical or horizontal angle. Initially, each LED represents a slope of 0.2 degrees. Once the device has been approximately levelled, however, the LEDs switch over to each representing one one-hundredth of a degree, allowing for "fine levelling."
