Observing & Recording
Metal Detecting
A high tone in the headphones, and nobody knows what it is until you dig
An entry-level detector and a small trowel get you started, usually on beaches, parks and ploughed fields where you have permission. Early finds are mostly bottle caps and ring pulls; the real skill is reading the tones until your ear separates iron from copper. Check the rules first, since heritage sites are off limits, and always fill your holes.
First stepGet an entry-level detector and a hand trowel, find a beach where detecting is allowed, sweep it for an hour, and sort every find by metal.
