Refill every hole immediately after digging — that’s mandatory, not optional.
Smart metal detecting etiquette means reading the environment before you break ground. Your survey strategies should prioritize low-impact zones like developed recreational areas and lawns where soil disturbance remains minimal and reversible.
Avoid digging near sand formations, as disturbing sand can qualify as geological feature damage under specific state codes.
