Expensive precision instruments don't always hold up to the extreme use that construction work places on them, but Hilti's new PR 30-HVS rotating laser tries to solve that problem.
Designed for leveling formwork, setting slopes and performing layouts, the 5.5-lb PR 30-HVS claims to be accurate to 1/8 in. at 100 ft, with auto-leveling and an operating range of 7 ft to 1,640 ft. Last fall, Hilti sent ENR a unit to test out.
