The Spectra LL300S Self Leveling Laser provides accurate horizontal laser reference up to 2,600 feet away. It features single-axis slope mode and a simple keypad for easy grade matching. Ideal for excavations, estimating cut and fills, and general elevation control, this rotary laser also has a highly rugged design allowing operation even in harsh job sites. The LL300S is self-leveling horizontally within ±5 degrees and has an accuracy of ±1/16 inch per 100 feet. For improved precision, the single-axis slope mode allows grade matching whilst the cross axis remains self-leveled.

The Spectra LL300S laser level has an out-of-level alert function that shuts off the unit if it is knocked out of place to prevent inaccurate readings.  It also has a 5/8 x 11 thread that allows contractors to mount the laser horizontally or vertically to a tripod.

Designed for durability and reliability, the Spectra Precision LL300S has a metal sunshade that offers superior drop and weather protection. The IP66 protection rating allows construction professionals to use the rotary laser in dusty environments or heavy rain. It can also withstand drops of up to three feet onto concrete and tripod tip-overs up to five feet. Using four D-cell alkaline batteries, the LL300S works up to 60 hours or approximately 47 hours with the optional rechargeable NiMH batteries.
