The Spectra LL300N Self-Leveling Laser is ideal for elevation controls, excavations, basic slopes, leveling forms and footers, concrete pours and more. It features a one-button operation, highly rugged design, and a single-axis slope mode that provides grade matching with a self-leveling cross axis for improved accuracy. With a working range of up to 1,650 feet, this rotary laser also includes a laser receiver for enhanced reception outdoors.

Self-leveling horizontally within ±5 degrees, the LL300N has an accuracy of ±3/32 inch per 100 feet and a 600 rpm rotation speed. It has a removable rotor cage that enables unobstructed 360-degree coverage and a 5/8-11 thread that allows you to mount it horizontally or vertically to a tripod. To avoid inaccurate readings, this laser level also features an out-of-level alert that shuts off the unit when knocked out of place.  Designed to work with the LL300N, the optional RC601 remote control allows construction professionals to access the self-leveling laser’s single-axis slope mode up to 100 feet away.

With an IP66 protection rating, the LL300N can withstand adverse environmental conditions, such as heavy rain and dust. Its patented lighthouse seal protects the rotor head and glass and offers superior drop protection. Using four D-cell alkaline batteries, this rotary laser works up to 90 hours and approximately 45 hours with the optional rechargeable NiMH batteries.
