1. Print out this picture on an A4 sheet.
2. Place the nails and a coin in the #1 position on the sheet.
3. Make a few sweeps with the coil in each direction (these ones are marked with arrows).
4. Place the coin in the #2 position, and repeat the test.
Hope your metal detector will easily pass this test. Or it won’t? More recovery speed tests can always be found here. Happy hunting!
