I will use it for topo with trajectories in overgrown fields similiar to what I usually do with my fourwheeler. I also plan on using it for grading work around the farm. I could see it being useful for construction stakeout as well. I get tired of waiting for the dozer man to move the big piles of dirt where the stakes go. JMT has Surface stakeout. I can connect it to an rtn or to tcp corrections from my base.
