Our range from Stabila includes self- levelling and ground line laser levels. The self- levelling laser level is a control tool which consists of a laser beam projector affixed to a tripod, levelled and then spun to illuminate a horizontal plane. The laser beam projector has a rotating head with a mirror to sweep the laser beam about a vertical axis. Laser levels where the mirror is not self-levelling have visually readable level vials and manually adjustable screws for orienting the projector. Laser line levels are used wherever accurate verticals and horizontals are required.
