Here's a nice little project we just did with the D5K regrading a couple bogs. The first pic is of a 2.5 acre bog that I skimmed about 1500 yds of sand over in 2 days. I basically ended up redoing the bog twice, because we got all the sand graded out once, and then the bog owner decided to save on sand he wanted me to cut the grade down another inch
Not a problem- punched the new grade in and went to town. Gotta love auto-grade systems!
This second pic is of an adjacent bog that a guy with a non-auto laser system on a D4K was hired to do. Since I finished my bog section early, I was asked to help the guy on the D4 finish up his bog section.
