Trimble pipe lasers 
The Spectra Precision DG613 and DG813 pipe lasers from Trimble are smaller in length than their predecessors, which is ideal when setting up the units in manholes with precast inverts and a tight radius. Both models have a grade range from negative 12 to 40 percent and are fully self-leveling over the entire grade range. The cross axis is fully compensated for quick setup and ensures the laser will be level. The RC803 remote control provides full function control and utilizes infrared communications when in the pipe at a distance of up to 500 feet. Flexible power options provide up to 40 hours of operation with NiMH rechargeable batteries and 50 hours with alkaline batteries; alkaline batteries can be used directly in the laser without a separate battery pack. 800/527-3771; www.spectralasers.com.
