Target Recovery
Target Recovery
Once you have pinpointed the target, it is time to recover
it. During target recovery, it is important to dig carefully
to prevent damage to the buried object, which can
significantly reduce it's value.
It is essential that you carry at least one of the
following digging tools with you while detecting:
• A pick with broad scraping blade (essential)
• A crowbar (for very deep objects in hard ground)
• A small, strong digging spade or shovel (for soft soils,
sand, etc.)
Recovering the Target
1.
Clear the area of loose surface material and check
that the target signal is still there. If it is not, the
target should be amongst the moved surface
material.
2.
Remember if there are other signals close to your
target.
This is important so when you come to dig your hole
you do not heap the loose dirt on top of another
target already in the ground.
3.
If the target signal is still present use your pick to dig
to a depth of approximately 50mm (2").
Note: When digging, avoid sharp edges to the hole as they
can produce false signals, potentially masking the target.
Slope the edges of the hole to avoid any problems.
4.
Sweep the coil over the hole to determine if the
target has been removed. If the target signal is not
heard then the target should be in the pile just dug.
Otherwise dig a little deeper and check again.
5.
Start digging approximately 100mm (4") in front
of the target to reduce the chance of damaging it.
Damaging a coin, relic or gold nugget may reduce its
value.
6.
If the target signal disappears from the hole sweep
the coil over the loose dirt and pinpoint its exact
position.
7.
Take a handful of the dirt and pass it over the coil.
Note: Your hands and wrists must be free of any metallic
jewellery and watches when passing dirt over the coil.
8.
If there is no signal, place the handful carefully in a
new pile, pinpoint the position of the target again,
and repeat with another handful of soil.
9.
Once the target is in your hand, transfer half of the
dirt to the other hand. Test each handful of dirt
across the coil.
10. If the target is too small to see drop the dirt onto
the top of the coil and with your finger move any
suspect objects. A target signal will only be given
when the target is moved.
Note: The GPZ 7000 is a 'motion' detector. This means the
coil must be moving over the target, or the target moving
over the coil, in order for the detector to 'see' it.
tIp
The GPZ 7000 is very sensitive and recovering
a small target from loose, dry soil takes skill
and patience. A plastic scoop allows you to
pass small amounts of soil over the top of the
coil to check if your target is in it. Carrying a plastic scoop
is a great way to speed up the recovery process.
CAUtIoN
Back Fill Every Hole You Dig
Always refill any holes, and scatter leaves
and surface debris, before leaving the area.
Help restore the area to its original condition to help give
detectorists a good reputation, and also disguise your
secret hot-spot! Any rubbish you recover should be taken
away with you and disposed of properly.
Refilling holes and removing rubbish will help detector
users maintain a good reputation. This should lead to
more areas being readily accessible for prospecting.
