Spectra Precision® LL500 Laser Level

Designed for long range measurements across your entire job site, the self-leveling LL500 features a 1, 600' ( 500 m) working diameter and increases productivity by reducing the need for multiple setups. The LL500 allows for easy one-person operation and features a built-in “ out-of-level� shutoff that maintains accuracy over the entire work area and minimizes errors. The laser transmitter sends a laser beam to provide an elevation reference that can be picked up by the included HL700 Laserometer. The HL700 measures and displays beam location and features dual-sided LCD’ s. The HL700 displays how far you are from on-grade, allowing for fast elevation checks without moving the rod clamp. A 127 mm ( 5" ) reception height speeds beam pickup in grade match and alignment applications. The HL700’ s anti-strobe sensor prevents construction lights from setting off the receiver so that true laser beam signals are more easily identified.
