The French company XP Detectors, also known as XPlorer, released two new white coils in 2017, both high-frequency. Do you want to know why the superfrequency 56 kHz? I’ll soon go to the mine, to the place where the guys lifted the scales, so my thoughts are cherishing the rise of Medieval silver small things with this new coil for my XP Deus metal detector, which I will share with you will answer the above question. A high frequency is needed specifically for collecting small things from fields that have already been walked and crossed with conventional low- and mid-frequency devices in the range from 3 kHz to 20 kHz (more rarely).
I bought the reel in the store «At Grandfather Mitya», it was sent by Russian Post, everything was very neatly packaged and the reel arrived without any dents or problems! And quite quickly — I was even surprised at the work of the Russian Post, but it’s still better to play it safe and insure the shipment, after all, almost 20 thousand rubles is good money for a new reel.

Coil configuration

For now, let’s take a look at the set:
Regular box. In these black boxes with the XP logo, the company supplies everything — from metal detectors to pinpointers with coils. Let’s discover this beauty. 🙂
Inside is a complete set that is necessary to use — new lower rod, battery for the coil and the coil itself with a supply of seals and bolts for the coil!
The stock, of course, pleases — prudently, in case they break or get lost, you won’t need to order new ones. The kit also includes instructions with a clear description of what and how to do, as well as a small training loop to help pull the coil wire through the rod, and then attach the battery to the connector in the wire. After this, the battery is conveniently hidden in the lower rod and has a small loop to make it easier to get the battery out in the future (probably for easier replacement). I would not recommend immersing such a kit in water.
The result is such a simple design. No charger included — use the standard one from your Deus metal detector kit.
Coil characteristics
The coil is round, with a diameter of 9″ or on our — only 22.5 centimeters. The reel weighs 349 grams, as seen in the photo below.
Weight, of course, without barbell.
The coil supports operation at three frequencies (not taking into account the frequency offset) — 15 kHz, 30 kHz and 55 kHz. If we take into account the frequency shift, then the frequencies are 21!
The 850 mAh battery ensures that the coil operates on a full charge for almost 28 hours. Not bad for a cordless coil with battery.
Although the manufacturer says that the reel can be submerged to a depth of 6 meters, but looking at its price, I won’t risk bathing it anywhere. Maximum in the rain, probably.
Productivity
In indoor conditions (it had already snowed outside), I conducted a small air test on three targets: a gold ring, the scales of Ivan the Terrible, 5 kopecks of Catherine II.
The frequency was 56 kHz, the settings were custom for mining coins (twisted for maximum productivity while exploring a new place). The result was interesting — 25 cm is stable for all three targets, but! Huge «BUT!» — frequency shifts VDI readings! Be especially careful with this and check the main possible targets in your location for VDI before the cop. For example: my gold ring at a frequency of 56 kHz showed 81-82, the scales showed 89-91 VDI, and 5 kopecks E2 showed 98 VDI! Wow. It turns out that the high frequency of the coil allows you to better see interesting targets that need to be dug. Unfortunately, I have not yet had the opportunity to check for a large silver coin (99 should be off the charts, probably) and for the gold 5 rubles of Nicholas II (the reference target).
I will soon add an update based on the results of the first dig at the place where the scales should be!
The first cop with a coil in a broken place!
I really wanted to go to the first spot with a new reel as soon as possible. Even despite the bad weather (snow and storm), I went and made no mistake — because the weather suddenly somehow miraculously became better! The snow was melting, there was no wind, a light rain was pouring, which could not disturb the cop on the field.
Finally arrived at the place. Usually a course that I have beaten for almost three years in a row! No matter how many coins were found there, it seemed that there would be nothing left to find! However, the hope of picking up a couple of scales or some other thin and small Medieval silver coins warmed my soul very much. That’s what happened, here’s the whole course of events:
At first I went from the edge of the field, the place was completely littered, there was a lot of modern and not very metal trash of different sizes, I carefully listened to every signal. I walked at a frequency of 54 kHz, and at this frequency the VDI is very strongly shifted, all the small metal rings like Catherine the Great’s Five Kopecks! Horsemeat rang first. And it rang exactly in VDI 97!
It’s strange, we often walked through that half-garbage dump and more or less all the large and not so copper signals had already been picked up. The horsetail turned out to be beautiful and in very good condition! At least hang it on a panel right now.
Then this silver token came out. The admixture was of very low quality, the signal was also incomprehensible, but at least at a high frequency it was clear that there was an object, although it was thin as foil, it lay at a depth decent for a high frequency — 20 cm. My inner instinct told me «dig» and for good reason! Nuremberg counter, 16th or 17th century.
Further, at a shallow depth, a small silver piece was raised, which in the end turned out to be a broken off small medieval coin. Again, at a normal frequency such a signal will go to waste, but in this case it was possible to catch the signal and accurately identify it thanks to the high frequency of 56 kHz! There is no photo of the rise, but in the general photo of the finds below this piece of coin lies in the middle of the block.
Then I came across a beautiful button. Interesting pattern, good condition, the depth was also quite large for 56 kHz — about 25 cm. The target in the headphones screamed very loudly!
At that time I had already moved quite far from the trash can and decided to switch the frequency to 14 kHz. What is the bonus of this reel — it’s very versatile! If it only had two frequencies — 20 and 54 kHz, then it would be very difficult to decide to buy it, but having in addition a third — 14 kHz, this coil can easily be used for ordinary coin digging and terrain reconnaissance. It will be very good in the forest, and in the stubble field too, and all thanks to its size — 9″.
Switching to 14 kHz, I almost on the surface picked up this second token for today. Also a Nuremberg counting token, but released later than the first — XVII century. It’s a pity that it has holes, it looks very nice for a token that is already over 400 years old!
Then there was a series of digging up various dubious signals, which did not bring anything meaningful. In general, even with such a coil, the Deus is a very loud device, you need to get used to its sounds and get used to it, because this cacaphony of different sounds can plunge any beginner into shock and horror! Of course, especially in a trash can, you quickly get tired of such an abundance of sounds, which is why it’s difficult to work in a trash bin for more than two or three hours. Or even less, depending on who you are.
But in the end a standard copper signal emerged — both the sound and the VDI (94) indicated that there was an old copper coin under the coil. A very good signal, to put it bluntly — reference for any metal detector! The coin turned out to be Swedish 1/6 öre, 1667. Beautifully preserved, the field did not disappoint!
A short summary of the cop. A small silver coin, which appears to have been broken, is in the middle. Then a copper Swede 1667, two counting tokens from Nuremberg — centuries 16th and 17th, various buttons and horsenecks. There is also one kopeck from 1973, which also came out from a fairly large depth for it.
The coil showed itself quite well! I was even glad that at one time I didn’t buy Deus with 9″ coil, because now there is no need for a regular black coil at 9″. This option will suffice: white HF coil 9″ and large 13″ coil, at this point the number of coils for the Deus will be optimal for a permanent cop — With a large black coil, you can walk through the fields and find places where coins are concentrated, and then use a white high-frequency to finish off the place itself. I’m thinking about selling 11″ coils for Deus and buying a big one because 9″ It’s even more stable and you can walk with it at a sensitivity of 95 or even 97 without any strong phantoms or fatigue.
