The LL1505C Laser Kit System from Spectra Precision is designed to meet the rigorous demands of professional horizontal alignment and elevation tasks on construction sites by integrating a premium rotary laser transmitter with field-ready accessories in one deployment set. The core unit offers automatic self-levelling in the horizontal axis and precision accuracy of ±1.5 mm at 30 m (1/16″ at 100 ft) and, when paired with a compatible receiver, supports a wide working diameter of up to 1,200 m (4,000 ft), enabling coverage of very large job-site spans. Its commercial-grade housing is sealed to an IP66 rating for full protection against dust and water ingress, and the unit is engineered to withstand drops from up to 1 m (3 ft) onto concrete and tip-overs from tripods up to 1.5 m (5 ft), helping maintain uptime and reduce repair costs. Included in the kit are a B10 NiMH rechargeable battery pack and a CH10 dedicated charger, providing reliable power for full shifts without interruption, and a Q104025 tripod offering stable mounting with standard thread interfaces. A 128995-00 system carrying case is also included for secure transport and organized storage of the laser and accessories. The built-in Bluetooth capability allows wireless operation from a smartphone or tablet using the Spectra Laser Remote app, and selectable rotation speeds of 300, 600 or 900 rpm along with height-of-instrument alert functionality, allow the user to tailor performance to specific site tasks and machine-mounted receiver workflows.
