RECOVERING THE TARGET
STEP 9 Keep halving the pile which has the target.
STEP 10 If it is still difficult to find the target, place the detector on the
ground with the coil horizontal.
STEP 11 Take a handful of the diggings and pass over the coil.
• Your hands and wrists must be free of any metallic
jewellery and watches.
STEP 12 If there is no signal, place the handful carefully in a new pile
and repeat with another handful.
NOTE Always refill any holes before leaving, and scatter
leaves, etc. to restore the area to its original condition. Any
rubbish you recover should be taken away with you and
disposed of properly.
Recovering Deep Targets
The ‘GP extreme’ has depth capabilities that will surprise both new
and experienced prospectors. If the target appears to be buried
deeply, it should help to use the following technique:
STEP 1 Use the cross sweeping method to locate the target accurately.
STEP 2 Dig a hole large enough to insert the coil, approx. 100mm deep.
STEP 3 Keep testing the target location as you dig deeper.
STEP 4 Take care that the target is not in the wall of the hole. You
may dig past it. Try pinpointing again to check your hole is in
the correct position.
REMEMBER Removing rubbish and refilling holes will help metal
detector users maintain a good reputation. This should lead to more
areas being readily accessible for prospecting.
When the object has been
recovered, it may be worthwhile
sweeping the hole again to
ensure that there are no other
targets.
If you find an object in a
particular location, search the
surrounding area very carefully. It
is likely that there are more
objects nearby.
If you hear a target signal, keep
searching until you find the
object; it is there and may be
valuable

Salty Environments
The ‘GP extreme’ will find objects at greater depth in salty
environments. However, the interfering signals caused by highly
concentrated salt may not be able to be completely 'balanced out' if
using automatic ground balance alone.
HINT Change Soil switch to Salt setting for salty environments.
To use the salt setting, you will have to use the specially designed
‘GP extreme’ range of coils.
