2 Pack Three-Head Green Laser Level with 2M Charger | 520nm Cross/Linear Laser Generator | Rechargeable Alignment Tool for Woodworking, Construction & Fabric Cutting (Base & AC/DC Adapter)

Premium Materials: Constructed from aluminum alloy, it is robust and durable. The larger the divergence angle, the longer the laser beam. Additionally, it can be used directly in cold weather without the need for preheating. | Clear Visibility: Featuring a 520nm super-bright green laser beam, it remains clearly visible even in sunlit workshops or outdoor work sites. It supports long-duration operation, making it highly suitable for use in the fields of construction, manufacturing, and interior design. | Rechargeable Version: Equipped with a built-in polymer lithium battery, it delivers an extended battery life and can be used without connecting a power cord. It supports 360 direction adjustment, comes with a USB port, and is controlled via an on/off switch for effortless operation. | Multi-Functional Design: Boasting an exclusive three-mode design (cross-line + single-line + single-point), it outperforms single-head competitors. It enables instant switching between drilling alignment (crosshair) and long-range cutting guidance (linear beam). | Easy to Use: It is fitted with a rear-mounted switch: press once for continuous illumination, and press twice to turn it off, ensuring user-friendly operation (note: do not keep it lit for more than five minutes at a time). A built-in laser module enhances heat dissipation, and the circuit board is designed with collection protection.
