Product Description
The Spectra Precision LL300N with CR700 Receiver Bundle delivers reliable performance for both manual leveling and machine control applications. The LL300N provides 3/32 in accuracy at 100 ft and operates over a 1,650 ft diameter, making it ideal for foundations, site prep, concrete pours, and excavation. Its automatic self-leveling design simplifies setup, while the Height of Instrument Alert ensures reliable results by stopping rotation if the laser is disturbed. With drop resistance to 1 m and IP66 weather protection, the LL300N withstands tough jobsite conditions.
The CR700 Combination Receiver adds versatility by functioning as a grade rod receiver and as a machine-mounted display receiver for mini excavators, backhoes, and skid steers. It features bright LED indicators, numeric elevation readout, multiple deadband settings, and patented light bar technology for consistent accuracy at any range. Together with the included aluminum tripod, 15 ft grade rod (feet/tenths graduations), and rugged system carrying case, this bundle is a complete jobsite-ready solution.
