I have a standard builders transit and a old worn out laser that was a hammy down, it died. I am now shopping for a new one and would like any experience with the leica rugby 100lr. I am just a basic site work contractor doing parking lots, housing developments, restuarnt lots, ect. Is the programable slop adjustment a huge benefit or no real big deal. The old laser had to be manually adjusted and I got efficient at it. If anyone has anything to add I will appreciate it.
