The Spectra Precision DG613G Pipe Laser is built for efficiency accuracy and reliability when laying pipes.The length of the DG613G has been reduced to make it easier to set up the lasers into tight inverts in the manhole. The DG613G 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 (500ft) providing full operation in a single set-up between manholes. The new RC803 remote control provides full function control and utilizes infra-red light in the pipe for up to 150 meter (500 feet) control. For “over-the-top” setups the remote utilizes radio communications up to a distance of 130 meter (430 feet).
