I finally saw the difference between old school digging and modern ground-penetrating radar
For years, I thought careful trowel work was the only real way to find things, based on my volunteer time at a local site. Then, last spring, a team near Tucson used GPR before they even broke ground and mapped a whole pueblo layout in two days. It showed exactly where to dig, saving months of guesswork. Has anyone else worked on a site where tech like that completely changed the plan?
