Abstract
A level, particularly a laser level is provided with a chassis simultaneously pivotable in at least a first direction and a second direction under the influence of gravity and a housing surrounding at least a portion of the chassis. The chassis carries a first light source for emitting a first light beam from the housing along a first plane and a second light for emitting a second light beam from the housing along a second plane.
