Notes from the bench
What we learn between test runs: what the numbers mean, what the spec sheets leave out.
- Can a metal detector detect gold?
Any detector finds a gold ring. Finding natural gold is a different machine, different ground and a different hobby. What separates the two, and what a beginner should expect.
- How to use a metal detector
Ground balance, sensitivity, swing speed and how to read the tones. The handful of things that separate a productive first session from an afternoon of digging nails.
- How deep can a metal detector detect?
Box claims describe large objects in ideal soil. What an entry-level detector actually recovers on a buried coin, and what changes the number.
