Frequently Asked Questions — Spectra Precision LL100N
What is the Spectra Precision LL100N accuracy?
The LL100N delivers ±10 arc-second accuracy, equivalent to ±1/16 inch per 100 feet. This meets standard construction leveling tolerances for suspended ceilings, partition layout, and site grading.
What is the working range of the LL100N?
With the Spectra HR320 receiver, the LL100N covers a 400-meter working diameter. Without a receiver, the visible red laser beam is detectable by eye to approximately 30-50 meters outdoors in daylight.
What is the difference between the LL100N and LL300N?
The LL300N offers an extended 700-meter working range, a faster leveling time of under 3 seconds, and better water resistance. The LL100N is sufficient for smaller projects and interior work where the extended range and speed of the LL300N are not required.
Can the LL100N be used outdoors?
Yes — the LL100N is suitable for outdoor use. It is not rated IP66 like the LL300N, so avoid use in heavy rain. The HR320 receiver extends outdoor usability significantly beyond naked-eye range.
What batteries does the Spectra LL100N use?
The LL100N uses 4x AA alkaline batteries, which provide approximately 75 hours of runtime. AA batteries are widely available on job sites and perform reliably in cold weather.
