The PM 40-MG is a multiline laser used for the adjustment of walls in drywall construction as well as supply lines and cable runs. It operates with a green la-ser beam, which offers better visibility than traditional red lasers. Even in bright daylight, it is clearly visible from over 25 metres away. To guarantee durability, diodes and prisms are protected against damage and rough handling by the Metal Blade Axicon technology. The rechargeable battery is also compatible with all other 12 volt devices by the manufacturer.
