How to read the conditions
Reflectivity is the fraction of laser light the target returns: a white board is about 90 percent, a building about 70 percent, grass and soil 10–30 percent. Visibility limits long-range figures because haze absorbs the pulse both ways. When two modules quote different targets, convert both to the same target before comparing; the open module database lists every vendor's condition next to its number.
