Recovering the Target
It is essential to 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.)
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.
