The automatic, self-levelling Spectra Precision® LL1505C Laser Level is the most rugged laser level available, tough enough to handle a wide variety of general and concrete construction applications. The rugged laser can withstand drops of up to 1 meter onto concrete and tripod tip overs up to 1.5 meters. This strength, combined with full weatherproofing and dustproofing, reduces downtime and lowers repair costs over the life of the product.
