Product Description


The Spectra Pipe Laser DG711 offers automatic dual axis self-leveling, +/-10 arc second accuracy, -15% to +40% slope, and positive and negative grade lights. The quick grade zeroing, line centering, line set, and line alert features simplify setting and resetting the grade and vertical line on the display and keypad. The DG711’s alignment markers, LED plumb light, and reflective target also make it easy to align the laser’s plumb line. Built for portability, yet durability, this waterproof pipe laser can handle any job.

Self-Leveling, Grade, and Line Features

The DG711 has a self-leveling range from -15% to +40%. Its quick grade zeroing resets the grade to zero while line centering centers the laser line on a reference point. Line set moves the laser vertically to its maximum limit and line alert flashes the laser beam if it is blocked.

Functional Display and Keypad

The large LCD display with a color coded keypad is programmable in 10 languages. It shows the set grade, line position, and battery status. Monitor your positive grade with the green LED light on the right side and your negative grade with the red light on the left side. Program your company name into the laser to show on the display as the laser powers up.

Superior Line System

Alignment markers, a LED plumb light, and a reflective target on top of the DG511 all assist in setting your line. The alignment markers work with the line centering function to align the laser to a distant control point while the plumb light identifies the pivot point and provides a reference for aligning a transit over the pipe laser. The reflective target provides a location for positioning a laser plummet or plumb bob.

Wireless Remote Spectra RC501

The Spectra DG511 pipe laser comes with a remote that adjusts the line and turns the laser on and off. Depending on your position, the remote operates over a range of 30 to 750 feet.

Lightweight and Durable Assembly

Built with aluminum, this pipe laser is lightweight and its handle makes it portable. A protective rubber bumper guards the pipe laser from physical damage. Yet, the DG511’s waterproof structure protects it from water damage with continuous submersion in up to 10 feet of water.
