The ML 13x is a semi-automatic Dual Slope Laser. Fast and Easy Setup – Fully automatic self-leveling allows the operator to setup with just the push of one button. No level bubbles or screws to adjust! Large ±9% (±5 degrees) self-leveling range makes this possible! During work, the automatic self-leveling keeps the beam horizontal, even as the laser is exposed to knocks and vibration. The large LCD display shows all setting and the battery condition. Rugged design – The ML 13x is built to be strong and robust, with the rotor head sealed in a glass housing, making the laser 100% watertight and dust-proof. 600 RPM makes the ML 13x perfect for machine control applications as well as use with normal handheld detectors. The ML 13x is supplied in a transport case with batteries, fast charger and Hand Detector HS 10. Staff and Stand is also included.
