Lobo SuperTRAQ— The Coin Hunter
Par Excellence
By Gordon S. Gibson
The date had been set and all the plans
were made-except one-what kind of detector should I take to
Quartzsite, Arizona to hunt for gold nuggets. I own several
general purpose detectors, but I wanted to increase my odds
of locating a lot of those hard-to-find nuggets and we all
know that requires a bona fide nugget detector.
But wait! I live 900 miles from the nugget fields and will
probably get to hunt for nuggets once, or if I'm lucky,
twice a year. It doesn't take a nuclear scientist to figure
out that it would really be a waste of money to buy a
detector that just found gold nuggets when I lived so far
from the hunt site. What I needed was a detector that was
very good at finding nuggets and was also very good at
finding coins and jewelry. After doing my homework and
talking to several dealers, I decided on the Lobo SuperTRAQ.
FEATURES

The SuperTRAQ has all the necessary
features to make it a good coin hunting detector-at least
that was what I was hoping for. When the detector arrived I
was anxious to try it out. But first, I needed to carefully
review the instruction manual.
The first thing that grabs your attention when reading the
manual is the Micro Controller ground balancing procedure.
The SuperTRAQ has three ground balancing modes-Normal,
Alkali and Black Sand. These modes, which are critical for
nugget hunting, are just as critical for coin hunting.
The Normal Mode, which I use about 98 percent of the time,
has a range that is smaller (has narrower parameters) than
the other modes. This allows you to keep from tuning out
smaller targets and will smooth out the sound caused by
mineralization.
The Alkali Mode is very similar to the Normal Mode except it
operates over a wider range of mineral signals. In this mode
the ground canceling capabilities may be slightly less
effective than the Normal Mode.
When mineralized conditions are almost impossible, then the
Black Sand Mode will be your choice. However using this mode
will cause a small drop in sensitivity.
As with most detectors that have ground balancing
capabilities, you need to ground balance the detector before
you hunt in either the All Metal or Discriminate Mode. When
I am coin hunting, I start off ground balancing in the
Normal Mode. If there is a problem ground balancing, I
switch to the Alkali Mode. If everything else fails, I go to
the Black Sand Mode. I have never used the Black Sand Mode
and very seldom use the Alkali Mode.
The rest of the controls on the SuperTRAQ are pretty much
the same as the other detectors.
The SuperTRAQ comes with a 10 inch elliptical widescan coil.
Optional coils are also available: 7 inch elliptical
concentric coil, 8 inch round concentric coil, 8˝ inch round
widescan coil and the 11 inch round widescan coil.
For most nugget hunting conditions, the widescan or double
"D" coil would be the choice because it handles high
mineralization the best. However, the widescan coil does not
discriminate as well as the concentric coil. Therefore, I
believe the choice for most coin hunting conditions would be
the concentric coil.
PRELIMINARY TEST
Since I purchased the SuperTRAQ six
months before the trip to Arizona, I decided to take it out
for a short test drive and just see how it operated. I chose
a site that I had hunted for the past 31 years for coins.
Every brand of detector had been used over this ground until
there wasn't anything left to find. I was more interested in
just getting acquainted with the SuperTRAQ than finding
coins.
The site was an old youth campground that dated back to the
1920's and silver coins had been found in large numbers
during my earlier years of metal detecting. I decided to
begin hunting on a hillside that was close to a swimming
area. Using the 10 inch elliptical widescan coil that came
with the detector, I ground balanced in the Normal Mode, set
the discrimination to '3', the sensitivity to '10' and began
to hunt. Immediately, I received a light target volume
signal that indicated something deep. The target sound was a
rounded sound with smooth edges, which for a Tesoro
detector, could be a coin. After digging a plug that was 6
or 7 inches deep, I recovered a 1938-D Mercury dime which
was in very good condition. Not bad for the first find with
a gold nugget detector!
After a few hours I was very impressed with the coin hunting
capabilities of the SuperTRAQ. I found four Mercury dimes,
several Wheat pennies, some clads and most of them were
deep. These were found in an area that provided me with a
very poor prospect of finding anything. It was then that I
realized I had something very special in my hands.
Since I was mainly interested in coin hunting, I decided to
purchase the 7 inch elliptical concentric coil to use in
trashy areas and the 8 inch round concentric coil for normal
use.
FIELD TESTS
In order to get a better overview of the
coin hunting capabilities of this detector, I think it would
be a good idea to take you on three coin hunting trips with
the SuperTRAQ to see how it performed.
The first stop was the beaches of South Padre Island. This
is a very popular tourist and swimming area in South Texas.
The beaches were bright white and the sand was deep. As I
was unloading my detectors (I always bring all my detectors
when I hunt) I noticed that there were not many people on
the beach. This was a good sign because I would have the
beach almost to myself. I decided to work the dry white sand
first.
I put on a concentric coil for better discrimination and
ground balanced in the Normal Mode. The sensitivity could be
set in the MAXBoost range and the discrimination dial was
turned to zero. (The MAXBoost feature is a high gain boost
over and above the normal maximum setting of '10'.)
At this point I wish I could tell you about all the coins
and rings I found, but except for a few new coins, coins
were almost non-existent. I tried all my detectors and got
the same results-no coins. I noticed a maintenance worker
and stopped to talk to him. I found out that the year before
they had very high winds as a result of a near miss from a
hurricane. The beaches were stripped of sand. During the
last few months, they re-sanded the beach with 2 to 3 feet
of new sand.
This called for a new plan of action. I decided to start
working the wet sand at the water's edge. I tried to ground
balance the SuperTRAQ in the Normal Mode over the wet sand,
but I could not get the sound to smooth out. I changed to
the 10 inch widescan elliptical coil and ground balanced in
the Alkali Mode. It worked! I set the discrimination to '1'
and the sensitivity to '7'. Since it was low tide, I worked
down the wet sand until I reached the water's edge.
It was slow work, but I started getting signals. I dug a few
encrusted coins that were surprisingly deep. (It was hard to
really tell how deep a target was because the water flowing
over the wet sand caused the sand to keep rolling back into
the hole.) I started working the side of a cut in the damp
sand and picked up another signal. This time I could tell
how deep the target was buried because the sand was hard
packed. After two big scoops full of sand were lifted up
with the long handle sand scoop, I spotted a man's yellow
gold wedding ring. This ring had to be buried at least 10
inches deep. I continued to work the water's edge for the
rest of the day and I filled my pouch with many coins. The
finds were not spectacular, but the experience indicated
that the SuperTRAQ was very good on the salt water beaches.
The trip to the beach required that I ground balanced in the
Alkali Mode and used the widescan coil to coin hunt. To me,
this was a big plus factor in favor of the SuperTRAQ. I
could change ground balancing modes to meet soil conditions
and change the type of coil (widescan or concentric) to get
the very best possible results. That was quite an advantage
over other detectors.
Our next stop to test the SuperTRAQ was a large city lake.
This lake was so trashy that I sometimes believed they had
built the lake over a trash dump. There was an over
abundance of pulltabs and screw caps. Beer cans could be
found at almost any depth along with foil and every other
conceivable trashy item.
On the plus side, there were some very old coins mixed in
with all this trash. The trick was getting past the trash
and locating the coins. This called for a small coil, so I
decided to use the 3 x 7 inch elliptical concentric coil.
This coil gave a very narrow search scan for target
separation and had excellent depth plus the discriminating
characteristics of a concentric coil.
I elected to start hunting in a picnic area near the water's
edge where people not only ate and played, they fished. I
ground balanced in the Normal Mode and started with the
sensitivity set to '7' and the discrimination knob turned to
'7'. (The discrimination of '7' is basically a "coins only"
setting. It would be impractical to lower the discrimination
to look for rings because of the tremendous trash problem.
Also, I learned many years ago that too high a sensitivity
setting will work against you in trashy sites.)
Working around large shade trees is always a good place to
start when searching a park so that was where I began the
hunt. With the discrimination set at '7', I should be
eliminating most of the trash, but I was getting a lot of
"chirps" and false trash sounds, so I lowered the
sensitivity to '6'. Now the detector was working more
smoothly. One of the first good signals I heard was very
strong. It could be a half dollar near the surface, but when
I went to the Pinpoint Mode to check it out, I found that it
was one of those blasted beer cans. The pinpoint mode on the
SuperTRAQ was just outstanding! Not only did it accurately
pinpoint the target, it also allowed me to almost outline
the target if it was large. The signal appeared to be almost
as big as the coil. This sure saved a lot of digging.
After many false trash signals, I heard that magic Tesoro
sound-a soft sound with smooth edges. I almost knew it was a
coin, and from the volume of the sound, I knew it was fairly
deep. After carefully removing a plug, the beautiful face on
a 1912 Barber coin was looking up at me. If this does not
start your adrenaline flowing you must be in the wrong
hobby! I was so fired up, I almost forgot to recheck the
hole. Again I heard that soft voice of the SuperTRAQ telling
me to look again. Digging another inch or two deeper
revealed a Captain Midnight children's pin which was in
excellent condition. But the most surprising thing of all
was what was lying two inches from the spot where the Barber
coin was located-a large bent rusted nail!
Trashy sites are difficult to work, but we must learn how to
overcome those conditions. I know one thing for sure, our
favorite sites were not going to become "less trashy." The
SuperTRAQ with the 3 x 7 inch elliptical concentric coil
handled the trash as well as any detector I had ever used.
That day I added many Wheat pennies, clad coins and a few
more silver coins to my collection.
Our last stop to check out the coin hunting capabilities of
the SuperTRAQ was an interesting historical site. This site
was located in a wooded farm area where a small creek
meandered between two hills and over a waterfall into a
large pool. The hill on the south side of the stream was the
spot where covered wagons destined for California circled
for the night. The stony surface on the creek just above the
waterfall was the road the wagons used to cross the stream.
This was one of the campsites on the "California Road" which
was the southern route across the Oklahoma Indian Territory
through Santa Fe to California. This was a busy route.
During June of 1849, 1,500 to 2,000 immigrants traveled this
trail.
As ranchers and farmers began settling in this area, they
used this same site to hold their social functions. These
industrious pioneers even built a long concrete, five foot
high, rectangular wall in the middle of the stream to make a
swimming pool. Over the years, the stream changed course and
the pool was filled in with silt. Beside the pool's wall was
a sloping grassy area that was used by the early families to
spread out their blankets so they could sunbathe and watch
their children swim. Later a cowboy dance hall was built on
the north hill which turned out to be a very busy and active
place on Saturday nights.
Three of my metal detecting friends, Carl McBrayer, Dan
Pierce and Tinker Browning accompanied me on this trip. We
were anxious to get to the site, but first, as you must
always do, we contacted the landowners to get permission to
hunt on this property.
It was a beautiful morning when we arrived at the old
campground. I decided to start my search on the hill above
the waterfall where the covered wagons camped. I had to keep
reminding myself that my purpose today was not relic
hunting-but coin hunting. My friends could handle the relic
hunting portion of this trip.
I put on the 8 inch round concentric coil because I was
interested in depth, discrimination and good ground
coverage. I ground balanced in the Normal Mode, turned the
sensitivity into the MAXBoost range and set the
discrimination to '3'.
As I began hunting I noticed that the ground was basically
free of trash, but the grass cover was very deep and thick.
I decided to hunt in the All Metal Mode because the coins
would be deep and then switch to the Discriminate Mode to
check targets. The All Metal Mode gave better depth
especially through this thick grassy carpet. (I should
probably mention here that the sensitivity setting on the
SuperTRAQ not only affects the Discriminate Mode but also
the All Metal Mode.) While searching, I noticed that there
was a flat grassy area on top of the hill. The thought came
to my mind that if I were spending the night in a covered
wagon, I would certainly pick this spot to camp. After
moving to the flat area, I very quickly got a soft response
in the All Metal Mode and then switched to the Discriminate
Mode where I heard a similar signal. I dug down about 10
inches and there it was -a 1879-S Morgan dollar in excellent
condition.
I yelled at Carl to come over and to take a look at what I
found. While showing Carl the coin, I moved the coil over
the hole again and heard another signal which was just to
the right of the hole. About 8 inches down was a beautiful
Barber dime. Wow! It was starting to look like this flat
grassy area would be a real hot spot!
Approximately ten feet away, I dug a 1926 Mercury dime at 8
inches. Then came a long period of no signals. I was just
about to change locations when I got a scratchy, "good
sound-bad sound." A very "iffy" target. Since the
discrimination was set at '3', I first thought that it was
trash because the setting was certainly low enough to detect
coins. But it had been so long since I dug for a target, I
decided to dig anyway. After digging an 8 inch plug, I found
a very dark Buffalo nickel with the date worn off the coin.
About one foot away I heard the same kind of response from
the SuperTRAQ. Guess what! Another Buffalo nickel and its
date was also gone. We all started noticing that the older
coins were very deep. Most coins were in the 8-10 inch
range.
Searching around the grassy tree covered hillside near the
old pool required a new strategy. This area had a lot of
trash so I changed the discrimination setting to '3' and the
sensitivity to '10' and worked in the discriminate mode. It
wasn't long before I received a good signal and at 7 inches,
I found a badly worn 1917 Walking Liberty half dollar. A
little later I uncovered a silver turquoise ring nearby.
The hunt was a smashing success. I found 4 Mercury dimes,
one Barber dime, one Morgan silver dollar, a Walking Liberty
half dollar, one silver ring plus several Wheat pennies. I
should also mention that Dan recovered two excellent finds-a
beer token from the Cherokee Saloon in the Indian Territory
worth 12˝ cents plus a 1914-D Wheat penny in excellent
condition.
CONCLUSION
So there you have it-three different coin
hunting trips using one of the Tesoro gold detectors-the
Lobo SuperTRAQ. Is it a good coin hunting detector? No! It
is an excellent coin hunter! It is very versatile. It offers
automatic computerized ground balancing with three different
modes for all kinds of soil. Is this important for coin
hunting? You bet! As a bonus, you have optional search coils
which are offered in the widescan and concentric varieties.
This really gives you flexibility in your hunts. On top of
all this, you have great depth, accurate pinpointing plus
that famous Tesoro sound for coins. That is an unbeatable
combination for coin hunting. It is truly a coin detector
par excellence!
Oh yes, I almost forgot to mention my gold nugget hunting
trip to Quartzsite, Arizona. I found 5 nice nuggets with the
SuperTRAQ and my wife found one nugget with the Bandido II
µMAX using the 4 inch coil.
