2-Wire Laser Level Gauge with 10m Distance and 3mm Accuracy for Wall Sticking and Ground Line Casting

Setting out accurate reference lines is essential for tiling, shelving, and partition installation. This laser level gauge projects a 2mm-wide line up to 10 metres, helping you align materials without guesswork. With 3mm accuracy and a choice of red or green light, it adapts to different lighting conditions and surface types. Compact and battery-powered, it is a practical tool for both professional tradespeople and DIY enthusiasts.

Features and Construction

The gauge combines straightforward operation with key specifications that support reliable indoor use. Its 2-wire configuration provides horizontal and vertical reference lines from a single setup.

Laser Type and Wavelength

The device uses a 635nm laser diode. Two colour variants are available: the SW-311R with red light and the SW-311G with green light. Green light is generally more visible in brighter conditions, while red offers longer battery life in typical use. Both produce a consistent 2mm line width.

Size and Practical Fit

Measuring 65.4x75x76mm, this level gauge fits easily into most tool bags without adding bulk. Its compact footprint means it can be placed on narrow surfaces or temporary workbenches. Two AA batteries power the unit, avoiding the need for a mains cable on site.

Uses and Placement

This tool is designed for marking reference lines in construction and decoration projects. Its 10-metre working distance covers typical room lengths and widths in residential and light commercial settings.

Wall and Tile Alignment

When sticking wall boards or laying tiles, a straight horizontal line helps maintain even spacing. The laser projects a clear reference mark that you can follow across the full width of a wall. The 3mm accuracy keeps deviations minimal over the working range.

Ground Line Casting

For floor installations, the laser can be positioned to project a line across the ground surface. This is useful for aligning floor tiles, underfloor heating layouts, or partition bases. The 2mm line width remains readable even on textured concrete.

Benefits and Buying Value

Choosing the right light colour and understanding the tool's practical specifications helps you get consistent results without overpaying for unnecessary features.

Red versus Green Light

Red light is adequate for most indoor conditions and typically uses less power, extending battery life. Green light is brighter to the human eye and works better in well-lit rooms or near windows. Both variants share the same accuracy and working distance, so your choice depends on the typical lighting where you work.

Why Choose This Product

This gauge offers a balanced set of specifications for general indoor alignment work. The 10-metre range covers most single-room applications, and the AA battery power source keeps replacement simple. Its 2-wire capability gives both horizontal and vertical references from one tool, reducing the number of setup steps required on site.
