Are You Walking Over
Nuggets?
Tips
on coil swing speed
BOB DANSIE
I often get calls and e-mails from
beginners who despite many trips to
known gold areas just can't find any
nuggets. They are going to patches where
others find gold but still come back
empty handed. I almost always know what
I will find when they join me for a
lesson. Almost without exception I see a
wild, fast, uncontrolled coil swing.
This will work just fine for large
shallow targets; bullets, nails and the
like respond just fine to this approach.
So will a large shallow nugget. But how
many of these are left on a really
hammered patch? How do some operators
find gold day after day on hammered
patches? The answer: A slow, calm,
plodding approach!
With a PI detector a weak, tiny, or deep
target will not be heard with the fast
swing. It's that simple. Rapid, jerky
movements can also cause false signals.
A very small nugget or a deeply buried
one will respond far more clearly if the
coil is being moved VERY slowly. Being a
motion detector it has to be moving a
little. In fact a target will fade away
rapidly if the coil comes to a total
stop over it. But just like with
medications, more isn't better. I can
make a weak signal totally disappear
just by increasing my swing speed.
Increasing swing speed can also increase
the signal response on hot rocks, hot
ground, and black sand. I can make the
signal response virtually disappear on
these unwanted “targets” by drastically
slowing my swing speed. On the other
hand, a good metal target will increase
in signal response!

This is where the slow swing comes into
play on a hammered patch. You are
looking for that nugget that got missed
by dozens of others who were there
before you. The chances of this
happening increase if the ground has
some difficult factors like those
mentioned above. By decreasing the
unwanted signals and increasing the
wanted signals you will hear that faint
signal that got passed up. The real pros
that use this method often don't even
actually swing the detector. The coil is
placed on the ground or very close to
it, and poked and guided around
obstacles. Taken to extremes like this,
virtually nothing is missed and I use it
often on the once very rich patches that
have really been hit hard. It might not
pay huge financial rewards but if it
gets you that first nugget it can be a
real eye opener.
Finding the first nugget no matter how
small is the most important milestone
for anyone who has recently gotten
involved with the hobby. Going home with
a nugget in your pocket will make you
love your detector and the dear
wife/husband may quit calling you a
fool.
These photos are of some nuggets I found
over the last few days using the
“creep-and-crawl” method on some of the
Bradshaw’s most pounded patches. The 3
smallest combined wouldn't even register
on my digital scales which take 1/10
gram to activate!

Now we'll get to the exceptions. When
hunting for new virgin patches you
simply can't cover enough country
scrubbing your coil on the ground. In
desert situations a new patch will
usually have some nuggets sitting very
close to the surface. It will often have
some large nuggets in the 1/4 ounce
range or bigger. There will be some
“sitting ducks”. The sitting ducks are
what you are looking for while patch
hunting. These will respond well with a
ground covering swing. A few years ago I
stumbled on to one of these. It wasn't
really a patch in the normal sense but a
vast area of gullies with nuggets in
almost every one of them. One gully in
the area had been extensively worked by
the old-timers, but the rest of them had
been totally ignored. I suspect that
this rich gully was so rich that they
never bothered to dry-wash the
surrounding gullies that were not so
rich. Since these poorer gullies weren't
messed with the trash was almost
nonexistent. Once I realized what the
situation was, I hit these surrounding
gullies very quickly swinging only for
the sitting ducks because I knew that it
was only a matter of time before someone
else stumbled onto the area.
By taking the sitting ducks I knew that
someone exploring at a searching pace
would be likely to pass through the area
empty handed. I could then return later
and pick up the smaller and deeper ones
at my leisure. It worked very well and I
still return to the area and get nuggets
on a regular basis despite the fact that
there are now club claims in the area.
As far as I can tell, no one has
stumbled onto it. This now has become a
pounded patch and the low and slow
approach is the only way to pick any
nuggets out of it. The few nuggets that
remain are either deep or very small and
I really have to work for them.
The beginner with no idea about geology
or indicators or how to recognize tell
tale signs of old-timer activity has a
slim chance of finding a new patch with
only blind luck working for him/her. It
does happen but it's akin to hitting the
lottery. They are far more likely to
find gold by carefully working some
known patches. Once they have seen
several of these patches then he/she
will have a good idea of what to look
for and with a few nuggets in the poke
will have the confidence to start
exploring for a new patch of their own.
Those who really pay attention to what
productive ground looks like and are
really observant of their surroundings
catch on fast. Those with their head in
the clouds, wandering around day
dreaming, or worrying about problems at
work or home will have a tough time. |
