Two 20‑min drone mag flights mapped 40 ha; ‘cost‑efficiency’ held, but we still spot-check with EM31.

We’ve found the ‘cost-efficiency’ really shows up when you plan tight tie‑lines and park a cheap 1 Hz base magnetometer for diurnal correction — adds about 15 min of setup but saves re‑flights and smoothing later. , powerlines and pit ramps chew up the data, so we bump AGL to about 60 m and run a few perpendicular tie‑lines for leveling, then do 25 m infill only where anomalies start to break up — does that match what you’re seeing?
