Troy Shadow X5 at Crow Creek, Alaska - 9/17/02

Troy Shadow X5 at Crow Creek, Alaska
I became aware of a new detector that
was going to be introduced awhile back. The Shadow X5 by Troy Custom Detectors.
The X5 is not intended as a nugget detector per se, but as a general purpose
high performance metal detector. What caught my eye was the operating frequency,
which at 19 kHz is much higher than the 6-10 kHz commonly used in many coin
detectors. That, and the fact that it has a manual ground balance. This
led me to believe the detector might make a very good all-around detector
for someone wanting to both coinshoot and nugget hunt.
I received an initial unit, and my bench tests confirmed this was the
case. The Shadow X5 is much more sensitive to small gold than most coin
detectors, and in fact I will go so far as to say that it will pick up gold
the vast majority cannot. Its gold performance is right up there with the
best of the dedicated nugget detecting units, and is better than a lot of
them.
Still, what was needed was a field test. I planned on getting out to
Crow Creek over the weekend to test the X5 on small gold. Troy Galloway
was kind enough to send up his new 7" concentric coil for me to use,
so I was raring to go.
Well, my weekend did not go quite
as planned. I ended up working Saturday, got tied up Sunday, and so took
Monday off to go to
Crow Creek Mine to test the Troy
Shadow X5. Then I made the mistake of stopping by work Monday morning, and
got caught. We were short handed, and so I worked again.
By Tuesday the good weather was gone, and a light rain was falling. Plus,
I found I had picked up a cold. But I was anxious to give the X5 a spin,
and so headed off to Crow Creek under gloomy skies and with a runny
nose. The place was empty when I arrived... nobody but Sean around. I set the X5 up with the
7" concentric coil I had been sent, and headed up the creek.
I stopped at a knoll not too far up the creek, and tuned up the X5. In
all-metal mode there are few controls to play with. I turned it on, and
set the sensitivity at max. Set the threshold for a bare sound, then pumped
the coil and ground balanced. Although the ground balance control is a ten-turn
knob, I found it took short adjustments to get the machine tuned for a slightly
positive response as the coil approached the ground.
I started scanning, and the X5 was very smooth, even though I had it
set at full sensitivity. It only took a few minutes, and I got a nice little
signal. A bit of work with my plastic scoop, and there was a small flake
that later weighed in at 0.6 grain (480 grains per Troy ounce). The coil
is very resistant to false signals, as I rubbed it in the soil and knocked
it against rocks with no problem.
In short order I found two more small nuggets, weighing
0.6 grain and
1.0 grain. I then wandered up the creek to a clay layer that usually give
a bit of trouble with high-frequency detectors, and located another small
nugget, weighing 0.7 grain. Also a small piece of lead shot weighing 2 grains.
At this point, my cold and the rain were wearing on me, and I had found
out what I had come for, so called it a day. Without splitting hairs I'd
say I can easily find gold down to about 0.5 grains at up to a couple inches
with the X5 and 7" concentric coil. Very impressive! The machine should
do even better with smaller coils.
Those unfamiliar with nugget detecting may wonder why finding these tiny
gold pieces is important. After all, it's the big nuggets we are after,
right? The fact is that in some areas all there is to find is smaller gold.
Even in areas with larger nuggets, the ability to find small gold can help
prevent boredom from setting in. But the bottom line is that most any detector
can find a very large gold nugget. It's the ability to detect small gold
in mineralized ground that really sets the gold machines apart from the
more common coin type detectors.
Anyone familiar with the Fisher Gold Bug or
Gold Bug 2 will feel immediately at home with the X5 in all-metal mode.
The machine is more sensitive than the 19 kHz Gold Bug, and actually
reacts more like the Gold Bug 2. Small hot rocks and the clay layer were
giving some responses that most lower frequency detectors would not. The
response on small gold is more mellow than the somewhat harsh, loud response you get with the Gold Bug 2.
A very pleasant audio tone, actually, but one that requires a bit more attention
than with the Gold Bug 2.
When run at max sensitivity,
the detector acts more like a higher frequency detector than a 19 kHz machine.
This is good when we are talking sub-grain gold. I also noted that I
was getting faint responses on rocks that normally only my Gold Bug 2 or
GMT with small coil will respond to. I suspect that in more mineralized
ground, or in areas with hot rocks, the X5 will get more ground response
than one would expect of a 19 kHz detector. I'm sure the sensitivity will
have to be backed off in places like that. I'll be curious to hear what detectorists in more
mineralized areas think of the X5. It's a rare area where you can run detectors
maxed out like I do at Crow Creek.
The 7" concentric coil only seemed marginally more sensitive than
the stock 9" coil to small gold. I would pass on it and wait for the
5" concentric due soon if small gold is the goal. There is also a 10"
elliptical DD coil in the works, which may help address some of the ground
response issues at higher sensitivity levels.
I did find a couple nails, and when I switched to the discrimination
mode I found it took a minimum setting of about 2.5 on the disc knob to
get them to audibly "break-up" and read bad. Unfortunately, the
gold weighing under a grain also wanted to be ignored. This is not surprising,
however, as sub-grain gold is smaller than most detectors can find at all.
The X5 is very hot in its disc mode, and for larger gold running more than
a few grains should see good use in iron infested areas. I'll have to explore
this more in the future. But for the tiniest pieces of gold, I'd stick with
the all-metal mode.

Again, I must mention the X5 is not
really a nugget detector, but an all-around unit. It has many features intended
for coin, jewelry, and relic hunting. I have not touched on these features
here, and will leave it to the coinshooting crowd to decide how the X5 works
for them. The machine should really excel on gold jewelry for freshwater
hunters, as the features that make it great on small gold nuggets should
prove valuable for earring studs, small rings, and thin gold chains.
To sum up, my initial reaction to
the Troy Shadow X5 is very positive. It was a pleasure to swing a detector
that only weighs 2.5 lbs. total, and the weatherproof design made for worry-free
detecting in the rain. The nugget hunting features are very basic by today's
standards, however. I don't want anyone to think I'm pushing the X5 as the
latest thing in nugget detectors. But it really is one of the few units
I've used that can really claim to "do-it-all". The Shadow X5
packs real power into a small package, and serious detectorists would do
well to keep an eye on this detector.
