Spectra gives you the perfect level meter for site prep and general construction with this Precision Combination Laser Meter (CR600). It can be either rod or machine mounted, making it ideal for a variety of applications.  Designed for tough construction site conditions, it is waterproof and has lightweight magnesium housing, which can withstand up to a 10-ft. drop onto concrete.  Its simultaneous super-bright LED elevation indicators visibly indicate grade elevation information to the operator even in poor light and up to 350 ft. in bright sunlight. Plus, the adjustable bandwidth lets the operator tighten the on-grade band to easily meet a wide range of accuracy requirements with tighter tolerances from rough grading through form leveling.
