84 85Choosing the Right Coil for the JobCommander Coils
Continued...
18” Round Double D
A serious coil for the serious operator. The 18” Double D
punches deep through heavy mineralisation, while running
smooth to allow you to hear those mellow, deep
nugget responses.
8” Round Monoloop
The most sensitive of the Commander series, the 8” round
provides the best depth on sub-gram nuggets in light
to moderately mineralised soils. A popular coil for use on
old diggings, it is also a great coil for detecting in heavy
vegetation, and is excellent on gold jewellery and small
hammered coins.
11” Round Monoloop
A lighter, more sensitive and deeper seeking coil compared
to its Double D brother, the 11” Monoloop is a brilliant coil for
almost any situation. The second most sensitive Commander
Monoloop, it is also one of the most stable Monoloop coils
available and remains stable in most soil types.
15” x 12” Semi-Elliptical Monoloop
On larger targets, this coil has better depth than the 11”
Monoloop and the 15”x12” Double D. It is very sensitive for its
size. This coil is great for searching open areas and also when
seeking out deep targets in areas that are too vegetated to
allow effective use of the 18” Monoloop. It is an extremely
stable coil and runs smooth in all but the worst soil conditions.
This coil has already become a favourite for many operators.
18” Round Monoloop
Superb depth and good sensitivity in low to medium
mineralisation. This coil will find targets in heavily worked areas
where other operators have given up.
There are five main things you should consider
when deciding which coil is best for your
terrain and target:
Coil Size and Depth
A larger coil will typically find targets buried
deeper in the ground but they can be less
sensitive to smaller targets. A smaller coil is
typically more sensitive to small targets, but
does not go as deep as a larger coil.
Mineralisation
A Monoloop coil will often have improved
performance over a Double D coil but can be
more difficult to Ground Balance and therefore
possibly more noisy. A Double D coil is often
more stable in heavily mineralised areas.
Terrain and Vegetation
A small coil can be easier to manoeuvre
through thick scrub or rough terrain. A smaller
coil is also a lighter weight than a larger coil.
Discrimination
In areas where discrimination is required a
Double D coil is necessary for Iron Reject to
work. In high trash concentrations a smaller
coil is preferable.
Search Pattern
A Double D coil will typically provide a 'blade-
like' detection pattern from the toe to the
heel of the coil, which gives excellent ground
coverage. A Monoloop coil has a detection
field that is typically cone shaped, which
requires overlapping of sweeps to ensure
thorough ground coverage.
Note: Third party coils and accessories are
also available. These are not manufactured,
warranted or supported by Minelab. Please
note that after market coils used with a GPX
Series detector in some Soil/Timings settings
such as “Fine Gold” and “Enhanced” are likely
to either not work or produce significant levels
of spurious signals from mineralised soils.
