Accurate Metal Detectors Gold Exorcist Gold Recovery Unit

By Andy Sabisch

Over the years I have conducted well over 100 formal and countless informal
field tests on new equipment. The vast majority has been with equipment that was
simply an enhancement to an existing product, such as a different type of
circuit or better discrimination capabilities on a metal detector, or a more
streamlined design of a gold dredge. The small number of remaining tests were on
equipment produced by someone that felt they had come up with a "better
mousetrap" when it came to treasure hunting equipment. Unfortunately, most of
these were disappointing at best when it came to real-world performance;
however, every once in a while something comes along that shows there are still
untapped ideas out there and they revolutionize the hobby in some way.

Ron Coen, owner of Accurate Metal Detectors, recently introduced a piece of
equipment intended to fit in the latter category. Ron is an avid detectorist and
multi-line dealer; however, his experience with prospecting was somewhat limited
when he started developing the Gold Exorcist. Despite what some might perceive
as a limitation, Ron had the vision to recognize the potential of a piece of
equipment brought to him and took over the development process. He solicited
input from seasoned prospectors, incorporated technology from the laser-printing
field, and, after modifying a number of prototypes based on his personal
experience and feedback from others, the Gold Exorcist was unveiled.

When Ron and Lost Treasure contacted me to do a field test on the Gold
Exorcist, I was interested to see if it was in fact a revolutionary piece of
equipment or one that simply looked good on paper, as so many other promising
pieces have been in the past.


The Gold Exorcist initially looks like a conventional dry washer and, in
fact, is intended to process material that, for best results, is at least 80%
dry. But other than its outward appearance, that is as far as the similarity to
dry washers goes.

Ron has been involved in the laser printer industry for two decades and, in
his work to improve on equipment available for fine gold recovery, came across
technology used in laser printers that could be adapted and used in the Gold
Exorcist project. This innovative design, currently awaiting final patent
approval, is what separates the Gold Exorcist from other dry washers or
electrostatic separators on the market.

The overall size of the filter (10x15) makes one wonder just how much
material it can process and how slowly you have to feed the concentrate through
it in order to avoid losing any of the fine gold you are hoping to recover.
The blower unit produces about 200 cubic feet per minute and,
with that airflow, it will process your dry, screened material about as fast as
you can pour it into the hopper. That sounds like a mighty tall-tale; however, I
and several fellow gold prospectors had the opportunity to put the unit to the
test and were not able to overload it to the point that gold made it through the
unit due to the inability of the unique filter to remove the gold. Accurates
claim of being able to process 20 tons per day may be dead-on, based on the rate
I observed material being processed through the Gold Exorcist (although I'm not
sure I'd want to have to move 20 tons of anything!).

The entire unit weighs 12 pounds and comes standard with an electric blower
assembly, classifier and a 10x15 filter assembly, which is the heart of the
machine. While the electric blower is ideal for locations such as campgrounds or
ones home where an outlet is available, a gas-powered blower can be easily
connected to allow the Exorcist to be used virtually anywhere.

The manual recommends that, for best efficiency, your concentrates or raw
material be both dry and screened to 1/8-minus. This preparation allows the
Gold Exorcist to process material at a truly amazing rate - just about as fast
as you can feed it into the hopper without overflowing it.

So, how does one operate the Gold Exorcist? First, collect as much material
as you want to process in containers up to 5-gallons in size (the weight gets a
bit overwhelming at that point). Running it from one container to another
through a classifier will quickly allow the material to be processed to the
right size needed to expedite the separation. Then start up the blower and begin
feeding the material into the hopper. It will quickly be passed across the
filter and the rejected material comes out the end. You can run for a good while
between cleanups; however, I (and others) found that 30 to 60 minutes was a good
run cycle. Once you have run the last of the material through, turn off the
blower and empty the filter unit into a gold pan. There may be a small amount of
black sand present, but for the most part you will be left with only the
precious metals that were once in your concentrates or virgin soil. The entire
process could not be simpler!

Field Test

Even the best-laid plans sometimes go awry and this field test was no
different. The day before the Gold Exorcist arrived, I found out that I had to
spend two weeks in Cleveland which put me in a bind to get some decent testing
done on this new device in time to support the magazines deadline. Luckily, a
co-worker, Tom Gaye, who was an avid gold prospector, offered to put the
Exorcist to the test with some black sand concentrates he had from numerous
outings to sites throughout the Carolinas. A few days after it arrived, Tom came
by and, in order to get his full, unbiased opinion, I gave him the box still
sealed as I had received it.

Toms feedback on the Exorcist started with the assembly process. Despite
coming with a rather abbreviated operating manual, the entire assembly process -
including unpacking the items from the box for the first time - took under 10
minutes. Subsequent attempts took a few minutes at most. He started out his
evaluation of the unit being skeptical at best, as he felt it appeared to be
incredibly simple and doubted that something as seemingly simple as the
Exorcist could possibly approach the claims made in the manual and literature.

His first test started with a 1-gallon mixture of black sand, tailings,
concentrates, and small gravel from the Cotton Patch gold mine in New London,
North Carolina. He was sure the material had some gold in it, since he had only
removed the larger pieces during panning and kept the remainder of the material
for future cleanup. The material was about one-third black sand, which he felt
would be a tough challenge for the Exorcist since it is typically difficult to
separate black sand and gold. The entire gallon of material was run through the
system in less than a minute, after which he removed the filter and carefully
dumped the contents into a gold pan. Surprisingly, he found a significant amount
of gold ranging from larger pieces (between 1/16 and 1/8"), missed previously,
down to small flour gold.

To test the efficiency of the unit, Tom took all of the material that had
been dumped out the end and ran it through the system again. This time the pan
had only a few pieces of flour gold, but nothing larger. A third pass produced
less than six tiny specks with virtually no size or weight to them.

Toms overall assessment of the unit was, I'm not sure about the claims in
the literature and on the website that say it retrieves 99% of all fine gold
with one pass, but I was pleasantly surprised that it seemed to work quite well.
One reason I may have gotten some flour gold on the second pass was that the
unit was bumped while dumping material in on the first pass and the instructions
do say not to tap it at all. The bottom line . . . it may not be pretty and
professional looking, but it really works. I'm not sure how, but it works!
[NOTE: The unit I received and Tom tested was a pre-production
unit and some of the edges had not been. This is the basis for the comment Tom
made on the appearance; however, despite the appearance, it still did an
excellent job in recovering the gold in his samples.]

When Tom brought the Gold Exorcist back I spent some time cleaning up a fair
collection of jars containing black sand, from sites I'd worked over the years
in Georgia, Tennessee, Idaho and Alaska. I'm like most prospectors in that I'd
much rather be out there dredging or sluicing than separating the fine gold from
the black sand at the end of the day. As a result, we all tend to collect large
amounts of black sand with thoughts of "someday" doing the final cleanupand for
any of a hundred reasons, that "some day" never comes.

As Tom found, it took no time at all for me to set it up and start processing
the first batch of dredge tailings. Within a few seconds I realized that setting
it up near the open garage door with a breeze blowing towards me was a bad idea,
as the dust began to settle inside the garage (and on my wifes car). I opted
for a better location at the edge of the trees on my property and simply ran a
longer extension cord.

With the Gold Exorcist relocated, I started by dumping a 2-quart container
filled with black sand from dredging I had done near my old home in Georgia.
Extremely heavy and concentrated, I had tried to pan some of the material down a
few years ago, but gave up due to the slow progress. Even with pouring the
material in slowly (OK, I was still skeptical), it took less than 5 minutes to
process several weeks worth of concentrated tailings. After removing the filter
unit and tapping it over a pan, all that was left was a few tablespoons of
material with a good deal of flour and flake gold easily visible. I spent about
30 minutes checking and re-checking the rejected material and was not able to
find any gold of note, even when inspecting it with a loop. Over the years, I
have tried or watched demonstrations of systems and techniques to recover fine
gold, and this was by far the easiest and seemingly most efficient I have come

Over the next few days I was able to process about half of the material Ive
had kicking around for quite some time, and was surprised to see just how much
gold has been sitting on my garage shelves all these years. I did try running
larger, unscreened material and found, even with that, the Gold Exorcist did a
more-than-respectable job in recovering even gold small enough that it would
float in a pan filled with water. The easiest method I found to prep the
material in order to maximize the amount it could process was to dump the dried
material through either a 4 or 8 mesh classifier. The larger material can easily
be checked for pickers and the classified material will flow trough the
Exorcist faster than you will believe until you see it.


While I and others contacted during the field test were initially skeptical
of the advertising claims made regarding the Gold Exorcist, we found it did
exactly what Ron claimed it wouldrecover even the tiniest specks of gold from
dry dirt or black sand concentrates in a fraction of the time other methods
take. In a few cases, the tailings from other separation systems were run
through the Gold Exorcist and additional gold was found in the filter unit that
the others had missed, even after multiple passes.

If you are a prospector and find yourself with an ever-growing stockpile of
black sand concentrates you plan to separate out, waiting for that rainy day
that never comes, take a serious look at the Gold Exorcist. In less time than it
takes to cook a turkey dinner, you will have recovered virtually all of the
treasure, finished your cleanup, and be sitting at the table admiring your
vial of gold (or platinum or silver) waiting for dinner to be served. It can
also be used to process virgin material in locations such as dry riverbeds or
old tailing piles (simply screen the material with a classifier and connect up
the gas-powered blower). In talking to some prospectors who have done just that,
their success confirms that the Exorcist will carry its own in those

The Gold Exorcist in the size tested - 10x15 - retails for $699 and
includes everything you need to recover fine gold once you get back to your base
camp or home. A gas-powered blower is available (or Ron provides suggestions
where you can buy one locally and save a few dollars) which allows you to use it
in even the most remote sites. Accurate also carries additional stock sizes and
units built to your custom dimensions which are available upon request. Another
indication that Ron Coen has confidence in his product and its durability is the
10-year warranty he provides on the filter unit, which is the heart of the
