I finally stopped hating the idea of ground-penetrating radar on digs

I used to think GPR was just a fancy toy that slowed things down. Then last spring on a site near Toledo, we spent a week digging test pits with zero luck on a suspected burial mound. The crew lead brought in a rental unit on a Thursday and we had a clear anomaly by Friday afternoon. Ended up finding a small hearth feature that matched the radar signature exactly, so I guess I can't knock it anymore. Has anyone else had a field experience that completely flipped your opinion on a tool or method?

Yeah but did you run the unit yourself or just watch?

Three years back I helped test a pilot unit for a community solar project in Vermont and saw how hard it is to get consistent data without proper load balancing. Most people skip that part and then wonder why their numbers don't match the manufacturer claims at the end of the month. Running the unit yourself matters but only if you know what to measure from the start.
