Field
Test by Ron Barnes
Having had the opportunity in the
past to field test several of Tesoro's prototype metal
detectors, to say I was thrilled when I received a phone
call from Heidi at the Tesoro factory would be an
understatement. There was a choice given as to which of
two machines I would prefer to "put to the test." When I
was informed that the new Silver 然ax would replace one
of my two top sellers, I chose the Silver 然ax. In my
mind I just had to have a hands-on showdown with the
detector that was supposed to replace the Cutlass II
然ax.
Since I had the notion in my mind that
"nothing" could replace the Cutlass in its price range, I
was stunned to hear that the retail price of the new Silver
然ax would remain the same price as the old tried and true
Cutlass. Upon arrival of the new machine, the first thing
that I noticed was an improved shipping container. It was
very securely packaged for shipping and reshipping. One
thing to remember about Tesoro-if it can be made better,
they will make it!
As I removed the machine from its
container, I immediately noticed the new faceplate design.
It is a very simple but well-designed arrangement. There are
two knobs and one toggle switch that control this little
lightweight powerhouse. I really like the word system in
place of numbers on the discriminate side of the faceplate.
This will help the new detectorist as well as the "old
timers." I cannot attempt to estimate the number of times I
have been asked by a customer why "they" don't put the words
there (i.e. iron, foil, etc.) and not just numbers. On the
sensitivity side of the faceplate, the number system is
still intact and I think it should be left as is. When I am
demonstrating a Tesoro detector, I always stress to my
customers that they should look upon the numbers around the
sensitivity knob as a speedometer in an automobile. The
higher the number, the faster (deeper) the machine can go
according to the existing ground conditions. On the
sensitivity level there is a "boost" range marked in orange
that can greatly enhance the depth capability of this little
dynamo.

The one toggle switch has three settings.
To the left is a Battery Check, the middle position is the
Discriminate Mode, and the right position selects All Metal
Mode. The Battery Check Mode is a nice improvement. In the
past when doing a show or in my shop, I had to warn the
customers of the loud battery check cycle that was normal
for the Tesoro. Most times, I plugged earphones into the
machine or put my handkerchief over the speaker to suppress
the loudness. A nice improvement!
After approximately 2 minutes (that's the
length of time it took me to assemble the Silver 然ax), I
proceeded out to my test garden which contains a variety of
targets, ranging from a small 10ct gold ring to an Indian
Head cent that have been buried in the test area for
approximately 15 years. The soil in my test area has mostly
a clay type of mixture. At the max sensitivity setting, I
had some chirping but all the targets were clearly
discernible. Now bear in mind, each target was buried 6
inches deep. I backed off on the sensitivity to about #8 and
there was no chirping, only clear signals over every target
especially in the All Metal Mode.
Switching to Discriminate Mode, I found
each target again but the small gold ring might have been
missed if I had not known it was there. It gave a very weak
barely repeatable signal, but the real story here is when I
switched to All Metal, the ring gave a very solid signal. It
was very obvious to me that this Silver 然ax would find the
gold in the All Metal Mode. Keep in mind that the ring was a
solid 6" down!!
The next day I was scheduled to do some
detecting with a buddy of mine that still hunts with his old
tried and true Silver Sabre II. I let him hold and swing the
new Silver 然ax, and he was astonished at its light weight.
This particular field is well-known to local detectorists
and has been "hunted out" for the past 15 years. The
location is an old colonial village that was destroyed by
the British in 1814 and saw some Civil War activity. We both
proceeded to work a zigzag pattern but not a whole lot of
targets were turned up. Part of the area had been roughly
turned over by plowing and it was as hard as concrete. The
total for approximately six hours of hard detecting was a
dozen or so modern brass pistol cartridges, four or five
brass shotgun shell heads, one-musket ball and several fired
.22 caliber lead bullets.
The next day I took the Silver 然ax to a
local salt water beach and spent several hours scooping
modern coinage from impressive depths in the dry sand. I did
note that upon entering the wet salt beach area, I had to
back the sensitivity down to about #4 before it became
completely quiet again. Even at that power setting, I dug
several badly corroded coins from 5" to 8" in depth.
A couple of days later another friend asked if I wanted to
hit "the field" again as he had a couple of hours free. We
met at the village site and proceeded to work our various
patterns. This time I decided to hunt in the All Metal Mode
and use the Discriminate Mode to weed out the trash. What a
shocker! In virtually the same area as previously detected,
I located the marked bowl part of a very ornate tablespoon,
an old brass shoe buckle and several nice colonial
dime-sized buttons. The real kicker was when I hit one
target and switched to discriminate to see if it was junk,
it disappeared. But flipping back to All Metal Mode it was
repeatable. Meanwhile my friend had ambled over to see what
I was spending so much time over (he hunts with a "Top of
the Line" competitor's machine). He checked the target and
got nothing. I disconnected the headphones and let him hear
the signal. He advised, "must be junk." Well, you know we
all have that little voice that sometimes we listen to, so I
proceeded to enlarge and deepen the hole. I felt I was
digging myself into it, as my friend was intently observing
my struggle to go deeper in the concrete-like earth. After
numerous silent prayers and approximately 10" down, what
should come to the surface for the first time in almost 200
years but the remains of an old pewter button with eyelet
still attached. The fertilizers had done their damage over
the centuries and all that remained was the center of the
button, that being less than the size of a dime. My buddy's
comment, "Man, I would not want to dig that deep anyway."
Yeah sure, uh-huh.
To summarize my findings, I am astonished
at the depth this low cost, high quality Tesoro Silver 然ax
can achieve especially in the All Metal Mode. Farewell
Cutlass, welcome home Silver 然ax!
P.S. At the time I was writing this field
test report, I was without a Silver 然ax. I had a customer
enter my shop the very afternoon I finished up the field
work on the Silver 然ax. This particular customer had been
trying to make a decision on which Tesoro he was going to
purchase from me for the past 18 months. Would you believe
he settled on the Cutlass II 然ax! When I gave him the bad
news about it no longer being produced, he became silent
instantly. I advised him of the Silver 然ax replacing it and
offered to demonstrate it out in my test garden. He
remembered from previous visits that the Cutlass had
problems with the small gold ring. When he walked over the
same targets including the small gold ring and got a clear
sharp signal you should have seen the look in his eyes! From
that moment he never took his hands off of my "only" Silver
然ax in stock. He insisted I let him have this one as his
wife had given him the checkbook and said, "Go buy your
detector." Adios, Silver 然ax! |
