| TESTS |
The following beach metal detector tests were conducted on a clay
sand tidal beach near Herne Bay, United Kingdom.
The tests were done by drilling a hole in the clay with an angle of
45 degrees to the surface.
The hole had to be with sufficient depth to allow maximum depth
measurement to be taken, when the coin is placed later.
The tests target (Silver Six Pence, Bronze Penny) was attached
with a tape on one end of a fibre glass bar (test bar), which end
was first cut with an angle of 45 degrees.
The hole which was drilled in the clay and the cut off end of the
test bar being set both at 45 degrees angle is a design allowing
the tested coin to be placed in parallel position to the ground
surface.
Also, having the test hole at 45 degrees angle eliminates the
presence of ground disturbance in front of the search coil.
In this way the test measurement is almost accurate as it would be
during real search.
The images below illustrate the test set up in full detail.
All measurements were taken in centimeters and later converted
to inches.
