My learning style is confabulation: make something semi-logical up and learn the truth when people crawl out of the woodwork to shoot you down: "The LIDAR function works and really gets close...at distances < 16 feet. Still, nothing you would use to mark a 2 x 4. Quite disappointed at how little the sales people knew about these functions." 
That is BAD wrong! About 50 yards fom my truck yesterday morning with no tape and needed to describe a mile mark from a point about 50' away. Wondered if the 16' LIDAR limit could be used in multiples. Tried it and worked fine BUT also noticed that with the right app, you could keep going. Just now went out into street to my steel taped 200' horseback course and tried it. Fixed one point and started walking. Was admonished to move slower once but at the end, without trying for precision, it said 200' 2". No idea what limit it is but this should work fine for description of miles at least that far.
