ROMER LOK Technology is  our Patented solution to eliminate "Leapfrogging" Error with portable arms.  Leapfrogging technique allows you to extend the volume of an arm beyond its physical reach.  By "Leapfrogging", you can move around an object with the arm and inspect in multiple different locations.  The drawback of this technique is that each time you leapfrog, error accumulates-- the more times you leapfrog from the original position, the greater the error.  ROMER LOK technology completely eliminates leapfrog error with a simple, elegant solution. It's a ROMER exclusive. Nobody else has this patented technology.  Read more about it in this section of the site:
