Cross line laser level SNDWAY SW-331G — green beam, 15 m range

The SNDWAY SW-331G cross line laser level projects perpendicular horizontal and vertical green lines for alignment and layout tasks with a working range up to 15 m. It features a rechargeable lithium-ion battery, IP54 dust and splash protection, and a compact, durable housing. The device includes a magnetic mount and a 1/4" screw thread for attachment to standard tripods or stands. Green laser lines are brighter than red, improving visibility in brighter conditions and over longer distances.

Advantages

The SW-331G offers automatic self-leveling with a pendulum lock for manual angle positioning, an outdoor pulse mode for use with a laser detector, and fast leveling in under 3 seconds. Its IP54-rated body resists dust and splashes, and the included magnetic mount plus standard 1/4" thread provide flexible mounting options. Rechargeable power and a 520 nm Class II green beam deliver higher visibility compared to red lasers.

Suitable for

• Interior installations such as cabinetry and wall decoration
• Tiling and flooring alignment
• Light construction and renovation work
• Outdoor layout with a laser detector (using pulse mode)

How to use

Place the SNDWAY SW-331G on a flat surface, attach it to the included magnetic mount or to a tripod using the 1/4" screw thread, and power it on. When unlocked, the self-leveling system aligns the beams automatically; lock the pendulum to position the laser at custom angles for non-level lines. For outdoor or long-distance work, enable pulse mode and use a compatible laser detector. Charge the built-in 3.7 V/1400 mAh battery via the supplied USB Type-A to USB-C cable.

Recommendations

Avoid direct eye exposure to the laser beam. Use the outdoor pulse mode with a detector in bright or long-range conditions. Store and operate the device within the specified temperature range and keep the unit clean from heavy dust to maintain IP54 performance.
