Laser Level Sourcing MTM330B 1x3D+1V cordless — self-leveling, compact layout tool

The Sourcing MTM330B cordless laser level projects one 3D line set (1x3D) plus one vertical line (1V) to create accurate reference lines for layout, alignment and interior installation tasks. This self-leveling tool generates straight horizontal and vertical lines for walls, floors and ceilings. Its compact body and battery-powered operation allow portable use on construction sites, during renovations and for fit-out work where mains power is unavailable or inconvenient.

Advantages

The device offers automatic self-leveling to ensure precise alignment without manual adjustment, and the projected 3D and vertical lines provide clear reference points for multiple surfaces simultaneously. Its cordless design enhances mobility and reduces setup time. The compact footprint and straightforward controls support quick positioning and faster workflow in small and medium-sized projects.

How to use

Place the Sourcing MTM330B on a stable surface or mount it on a tripod at the required height and roughly orient it toward the working plane. Power on the unit and allow the self-leveling mechanism to settle; the instrument will automatically generate straight horizontal and vertical reference lines. Use the projected 3D and vertical lines to mark positions and align fixtures, tiles or profiles. When working on long distances or in bright conditions, use additional measuring aids or a detector if supported.

Usage recommendations

For best results, set the device on a firm, vibration-free surface and avoid moving the unit while lines are being projected. Check battery charge before starting tasks and carry spare power if extended runtime is needed. Protect the laser aperture from dust and impacts and follow standard safety practices for laser tools: avoid direct eye exposure to the beam and keep the unit out of reach of children.
