There's a few ways to do it with GPR. Carry it on a back pack and hold a antenna pole while you walk. Planes/helicopters can use it, subs and rovs, and now remote control cars and drones.

We're getting smart about this stuff and it's opened up so much. Making maps of things we can't see like roads and trenches and tombs we never knew were even there.

Still have sooo much to scan but it's an exciting time for archaeology.
