Treasure Locations
A question most new detectorists ask is,
“where do I find treasure”? There are actually
lots of areas in which you can search. It is
best if you research where people have been
in the past, what type of objects they might
have had with them, and hopefully lost. You
can also go to areas people still use on a daily
basis such as the beach or parks, and search
for modern coins and jewellery.
Here is a list of some of the more productive
places to search:
– Your own backyard
– The beach
– Showgrounds & racecourses
– Picnic areas
– Battlefields
– Camping grounds
– Swimming holes
– Parks and playgrounds
– Ghost towns & ancient town sites
– Old homes & public buildings
– Old gold mining sites
– Sports grounds
– School yards and ovals
– Around jetties and piers
– Drive-in theatres
There is a chance of finding buried treasure,
such as coins, relics and jewellery, anywhere
that people have been in the past. In order
to maximise your return, select sites that have
the most potential.
For example, a small park that is just used
as a walkway between houses is likely to
be littered with junk with very few valuable
targets in it. Whereas a larger old park with
picnic tables, playgrounds, etc. would have
had thousands of people sitting around,
playing sports, laying on blankets etc. and
you can almost be certain that there will be
some goodies waiting for your metal detector.
Be sure to obtain the land owners permission
before searching on private property, be sure
to also check local regulations.
Note: Always check your local regulations and
laws before detecting in a public or private area.
Always refill your holes. If you leave the
ground exactly as you found it, you shouldn’t
have any problem detecting the same area in
the future.
Recovering the Target
A trowel, knife or small spade are good tools
for recovering targets.
Once a target has been located, clear the
surface of loose material and check again for
a signal. If there is no signal then the target
is amongst the surface material. In this case,
search the surface material until the target
is located. If the target is still in the ground,
Pinpoint its position.
Using a sharp tool, cut a neat portion of grass
or soil and place it on a plastic sheet. This
prevents the material being scattered around
and allows the hole to be refilled quickly.
Dig carefully to avoid defacing or devaluing
the object.
Ensure that no other targets remain, then refill
the hole. All soil and portions of grass on the
plastic sheet should be returned to the hole
as neatly as possible. Step lightly on the soil
to compact it.
Check the hole for the target. If it is not in
the hole, place the detector on the ground
with the coil flat, pick up a handful of soil and
pass it over the coil. Be sure not to wear rings,
bracelets or a watch which will produce a
signal. Repeat this procedure until the target
is located.
Leaving holes, or a scarred area, may result
in action being taken to prevent the use
of metal detectors. Please ensure that you
remove all rubbish. The aim is to leave the
area of ground exactly as you found it.
