My hand drawn site map showed a wall my total station missed

Last month I was mapping a small Roman farmstead near York and my total station data looked clean, every point clustered where the geophysics said it should be. But I did a quick pencil sketch of the visible stone lines while waiting for the battery to charge, and that drawing had a faint linear bump running diagonal to the grid. Turns out the instrument was picking up modern drainage pipe reflections, not the actual foundation, the real wall was 1.2 meters south under a thin topsoil layer. I've always trusted the tech over my eyes, but now I'm second guessing every processed dataset from that dig. Has anyone else had a hand drawn plan catch something their equipment completely missed, or am I just being paranoid about old school methods?

Oh man, this hits so hard! It's like how my phone's GPS once told me I was in a pub across town, but my own eyes could see I was actually standing in a garden center, you know? We've gotten so used to trusting the gadget over our own senses, and then when the two disagree, we assume we're the ones who screwed up. But honestly, your hand is just another kind of instrument, one that's been doing fine for thousands of years. Maybe the real lesson is that tech gives you a great starting point, but it still needs a human double check, kind of like how autocorrect never gets my slang right no matter how many times I fix it. I bet half the stuff we "miss" on site is just the machine being too smart for its own good.
