The DG613G is a green beam version of the popular DG613 from Spectra.

It has a grade range from -12% to +40% and is fully self-leveling over the entire grade range. Even the cross axis is fully compensated - providing quick set up and peace of mind that the laser will be level without having to adjust at the bottom of the invert.

The DG613G works over a distance of 150m providing full operation in a single set-up between manholes. The RC803 remote control provides full function control and utilizes infra-red light in the pipe for up to 150 meter control.
For "over-the-top" setups, the remote utilizes radio communications up to a distance of 130 meters.
Flexible power options provide 30 hours operating time with NiMH rechargeable batteries and 50 hours with alkaline batteries.
Alkaline batteries can be used directly at the laser without a separate battery pack.

The large graphical user interface can be seen easily when the laser is in a manhole. All functions are available via graphical menu which makes it simple and easy to use – no secret button pressing and short learning curve means it can be handed to anyone in your crew with little or no training.
The same graphical user interface is used at the RC803 remote control.

The Spectra Precision DG613G has advanced functions that make setting up and using it easier and more accurate:

Line-Set, check allows the laser to shoot the beam upwards to align to the next manhole from a short, deep trench as the beam will move up to 100% in seconds.
Line scan allows the beam to sweep quickly (left and right) and can be stopped on the target at the bulls-eye position using the remote control. Line Alert is automatically activated once the grade and alignment are set –warning the user that the set-up has been disturbed, avoiding costly errors and re-work.

The DG613G is supported by a manufacturer's 3 year warranty.
