Tesoro 12x10 Web coil
This 12 x 10 tejon coil has been on the market since the release of the Tesoro
Tejon a couple of years back, and I must say it has never really appealed to me
not only the extra weight but the fact that a high frequency machine such as the
tejon is designed for finding small targets in badly contaminated soil, I have
always believed a large coil on a highly sensitive machine would confuse things
due to the search head passing over several targets at once resulting in audio
chaos. This is what I told a friend Kevi when he announced he was going to buy a
12x10 widescan for his Tejon, his mate up in the North has one and was
apparently having great results even on small targets.
It wasn’t long before I got a phone call from Kevi to say I was wrong about the
coil, and to quote “ get one and see for your self”.
His visit had been to an old site mainly looking for a hoard that he believed
was in the area, what really impressed him about the 12x10 web coil was it’s
sensitivity to small targets, claiming a handful of Roman coins and fragments.
I decided to try one on my Tejon and indeed Kevi was right, despite the size
this coil was sensitive to small targets. Later that week I attended the weekend
wanderers rally at Eddlesborough and set up my humble stand, it was really good
to put names to faces. I took along the Tejon with the 12x10 widescan coil and
set up a simple test for all to try.
A small tub of dirt taken from my Roman site 3 inches deep and contaminated with
tiny iron fragments, underneath the tub was a small Roman bronze coin. Out of
all the machines tried only one other managed to locate it with a clean signal,
the Tejon found it 3 inches above the tub even with the sensitivity set at 2.
Jaws dropped and word soon circulated amongst the detectorists. Throughout the
day I was constantly showing the same experiment over and over again.
OK you tekkies are probably saying that’s not a fair test, the coin needs to be
buried which is probably true, I use this test to quickly evaluate a machines
capabilities before field testing, 5 years ago the only machine that gave a
slight target response on this experiment with exactly the same soil and coin
was the Lobo, so things have moved on slightly.
I took the Tejon to my usual site where one field is badly contaminated with
Iron, the machine was a little unstable at first with my standard settings, but
with a little fine tuning the Tejon worked like a dream.
One thing you must remember about this machine settings are very close and a
small control adjustment can make a big difference, so you must work closely
with the sensitivity and discrimination controls on every field to obtain the
During my 3 hour search I had some really small targets, a tiny hammered almost
disintegrated with a hole in the middle this coin gave a very clear 2 way signal
at about 3 inches deep. 2 roman bronzes, a strap end, and a very nice Roman
brooch. Not to mention some buttons and the usual non ferrous junk, I dug 4
pieces of Iron including an Iron ring and buckle.
Yes a very
sensitive and well behaved coil, I can honestly justify paying the price.
A little heavier but well balanced, still lighter than the Explorer and XLT.
Iron identification very good, in fact better than the web coil.
Without a doubt deeper than the standard coils on all sized targets.
Fantastic build quality.
Price £170.00 inc coil cover, cheaper than a hoard hunter !!!
This is the only coil I use
on the Tejee now and running the sensitivity at zero puts this machine into a
class of it's own.

The optional coils will fit other 4 pin Tesoro's but works best on the
Laser Trident II
Laser Trident Extreeme
Will also fit but may need re calibrating
