Some advices
The Golden Mask 5+ comes in a standard set with a 23 cm (9 inch) dual-frequency Spider
search coil. A coil with this size is considered universal - it could be used with success in
every aspect of metal detecting - from gold prospecting to treasure hunting. Of course,
there are better option for these, but the 23 cm Spider also works quite well.
You can buy additional coils with different size and shape from 13 cm to 32x38 cm. The
GM5+ is compatible with all dual-frequency coils produced by Golden Mask. These have
an orange or yellow point on the cable protector at the coil top. Non-compatible coils do
not have the same point or have a white one.
Smaller coils are better for small targets as gold nuggets, jewellery and small coins, while
the larger coils are best for large targets - large coins, relics and treasures.
Larger coils are not always deeper. Depth depends on the target size and the working fre-
quency. For tiny gold jewellery a small 18 cm or 23 cm coil and 18kHz working frequency
will work better than a larger coil. Even more, you could easily miss small jewellery and
tiny coins if you search with the a large coil. Larger coils are deeper on large targets only.
Larger coils are harder to ground-balance, especially on mineralized ground and at 18kHz.
For beach hunting, where a combination of both mineralization and conductivity is
present, a smaller coil will work better and will be ground-balanced easier.
We recommend using the 18kHz working frequency always when possible. At 18kHz the
detector achieves maximum speed and depth for the most common metal detecting
activity - coin shooting. At higher frequency, the detector is more sensitive to low conduc-
tive metals as gold and tiny objects. You can do some air tests for yourself and you will see
this is true.
Speaking about tests, do not try to test the detector at home - in every house or even far
from a house there are always too many electromagnetic interference (EMI) fields that will
disturb the detector and you may think something’s wrong.
On sites with not too many targets, try to use the All metal mode - this will give you 2-3 cm
more depth. If you cannot get used with All metal mode, try to use the Mono tone mode.
On mineralization, decrease the Gain and the PowerBox settings until the detector be-
comes calm. On strongly mineralized ground, a low value of the Gain very often gives you
more depth and more correct discrimination.
Try to swipe the coil near the ground, but without touching it. Do not move it too slow or
too fast. With practice, you will find the appropriate speed.
Pay attention on the sound. With practice you will learn to successfully distinguish differ-
ent sounds. Some experienced detectorists can distinguish different type of targets with-
out even looking on the screen. For example, you can easily distinguish the sound from a
coin and a lead bullet, just have to listen carefully. But to do this, you will have to practice a
lot. This is the same as with car driving - remember your first days driving?
Respect the private property. Do not search in private property without permission - this
could lead to serious legal, financial or other type of punishment.
Respect the law in your country about the protection of historical heritage and archeo-
logical sites. In all countries in Europe it is strictly prohibited to do metal detecting on or
nearby archeological sites.
Cautions
Keep the detector electronics and battery compartment from water and moisture. Be very
careful when placing your detector on wet ground - moisture can penetrate batteries and
brake the electronics inside the battery compartment.
Keep the search coils from mechanical impact - stepping on your coil almost always brakes
it, and the warranty does not cover this. The search coils are water-proof. You can wash
them or submerge them in water - no problem.
Keep the coil connector from dirt and moisture. The good contact between the coil and
the detector is essential for the performance of the machine.
Do not use other charger than the supplied with your machine. Third party chargers may
be very dangerous for the batteries and may cause fire.
Do not forget to turn off your detector after you end searching - this could ruin the batter-
ies and the electronics inside the battery box.
Good Luck!
