The rugged Spectra Precision® Laser LL300N is a medium-range, highly accurate leveling solution designed with a metal sunshade. The LL300N provides superior drop and weather protection, having been built to withstand a drop of up to 3 feet directly onto concrete or up to 5 feet when pushed over on a tripod. Performance is maintained even in rainy, dusty or other harsh job site or weather conditions.

Get set up quickly and accurately with the LL300N and its fully automatic self-leveling capability. The LL300N keeps working even with loss of power with a rechargeable Ni-Cad battery pack or alkaline batteries. Maintain accuracy in the cross-slope while grade matching for basic slope work with the LL300N’s single cross-axis manual slope mode with cross-axis self-leveling.

The LL300N comes with your choice of the HL450 or HR320 receiver, ensuring you get the best option for your application. Kits with the LL300N are available, with it shipping in a system case with the receiver, tripod and grade rod.
