Features & benefits

  • New reduced length allows easy set-up even in tight inverts
  • Large, bright, graphical user interface makes the screen easier to see and use when in or out of the pipe. Same graphical user interface can be seen on the remote – what you see on the laser you see on the remote.
  • Self levelling range of -12% to +40% over the entire grade range
  • Cross axis compensation provides a quicker more accurate set-up as the laser does not have to be level in the pipe – place it in the pipe it levels, you work.
  • Bright visible beam that works up to 150m (500ft)
  • IP68 protection (dust and waterproof)
  • The DG813 has flexible power options that provide 40 hours operating time (NiMH rechargeable batteries with worldwide charger) and 50 hours (alkaline batteries). Alkaline batteries can be used directly in the laser without a separate battery pack. Additional car charger can be purchased to keep you working even when out in remote areas.
  • Line-Set/Check – allows the user to align the laser to the manhole quickly and easily to set direction. The beam will go up to 100% allowing easy alignment even in short trenches
  • Line Scan – provides a quick alignment to the center of the target for the second day setup
  • Line Alert– notifies the user if the set-up is disturbed eliminating costly re-work from errors

With SF803 Spot Finder, smart functions are available:

  • Spot Align - automatically aligns the DG813 to the center of the Spot Finder in the pipe or to the direction of the manhole when used in a deep, short trench or for "Over the Top" set up.
  • Spot Match - a great tool for checking that pipe has been installed to the correct grade or for finding the grade of existing pipe work. Can also be used to calculate the grade between manholes.
  • SpotLok - can be used to easily establish a steep slope reference at mountain areas or to lock the beam in a desired position for applications such as solar farms where the beam could be subject to drift.
  • Spot Search - can be used to manually locate the beam over long distances out of the trench when using the "Over the Top" application
  • RC803 remote works via radio 130m (430ft) or infra-red 150m (500ft) for both "Over the Top" set-up and in pipe/trench set-up.
