Trimble Spectra DG511 Lasers & Levels

The pipe laser is an easy-to-use tool that provides underground contractors line, elevation, and grade control for installing storm, sanitary, or other gravity-flow pipe. This system can also be used for tunneling, boring, pipe alignment, or any other application requiring line, elevation, and grade control.

Your job sites involve some of the harshest conditions found in any industry. You need equipment that can stand up to corrosion from acids, chemicals, salts and other destructive underground elements, as well as to the physical abuse typical in the construction industry. The Spectra Precision Laser DG511 pipe laser from Trimble is designed to meet those conditions


Built tough for long-lasting performance and reliability, the DG511 pipe laser is completely waterproof and designed to ensure easy cleanup. They are also easy to assemble with a full range of setup accessories available, and easy to use with straightforward, “no-instructions-required” controls. They even keep track of their own maintenance needs, notifying you at regular intervals (you decide how often) when it’s time for a checkup. The DG511 pipe laser is simply the toughest, smartest tool you’ll ever own!

The pipe laser projects a highly visible red beam of laser light in a direction at a predetermined (grade) for the alignment of gravity-flow pipe. The laser light is intercepted by a target. To align the pipe, you need to position it so that the pipe laser’s beam is centered in the target.
