A tenths rod and tripod round out the kit, giving your crew a complete, calibrated system right out of the case. Whether you're leveling footings on a commercial build, establishing drainage grades on a subdivision, or checking floor flatness on a slab pour, this package has the range and accuracy to get it done.

Job Applications
Site Grading & Earthwork: The 2,600 ft working diameter gives machine operators and grade checkers room to work across large pads without repositioning the instrument. Pair with the HR320 receiver mounted to a grade rod on the blade or bucket for efficient cut/fill operations.
Foundation & Footing Layout: Establish consistent elevation benchmarks across a foundation perimeter quickly. The LL1505C's ±1/16 in. accuracy at 100 ft keeps footing elevations tight across the entire structure.
Drainage & Pipe Installation: Set consistent fall grades for storm drain, sanitary sewer, and utility trenching. The selectable rotation speed and HR320 receiver make reading grade at the pipe invert straightforward even in variable light conditions.
Concrete Flatwork & Slab Pours: Use the laser reference plane to screed and check floor flatness on commercial slabs. The self-leveling function means fast, repeatable setup each time you move the instrument.
