ENGLISH: New XP 9″ DD HF coil/detector – Simply AMAZING!!!

(c) 2017 by Leonardo Ciocca – AMD Tech Team

It’s being a few months since the french manufacturer XP has launched the new HF 9″ coil for its flagship detector, the DEUS. The french company, very kindly, has sent to me a complete unit (including a remote control, 9″ HF and 11″ Standard coils/detectors, a MI-6 pinpointer and a WS4 wireless headphone) updated to 4.0 firmware release, needed to use the new high frequency coil.

For everyone who was astonished by the article’s title “…coil/detector…”, I’ll go straighforward to the explanation of that expression.

For years, majority of metal detectorists (Deus owners or not) has had always considerated the its coils…just coils… but this is not completely true!

TEST: Detech Ultimate 13” for Garrett AT PRO: more power!

by Leonardo Ciocca © 2016 AMD Tech Team

People who use the Garrett AT PRO since a long time know very well its potential. With the stock coil, a DD “Smudged” 8.5”x11”, you have very good performances on different soil conditions. Obviously you cannot expect “spectacular” results from a coil that, even if very well designed, is made for general purpose treasure hunting, and fits well to beginner and expert users at the same time. It has a good depth, good target separation and, after all, it is not so heavy.

But what could we do if we want some more?

Here they come some third party manufacturers, especially from East Europe, that started making some alternative coils that could be mounted on the Garrett’s hi-end VLF machine. We, at AMD Tech Team, have already tested and reviewied a couple of them with very nice results. Now is the time to test the Detech Ultimate 13” DD, flagship coil of the Bulgarian company run by Eng. Rumen Kanev

XP ADX 150: Lots of power, simplicity and lightweight… for everyone!

Spring has finally come and rainy days seem to have gave us a little peace. I was impatient to go back on the field because, as you may have read in the blog, during this period the AMD Tech Team was literally “loaded” of metal detectors to be tested and reviewed.

In between all those machines that were kindly sent to us, we had the XP ADX 150, distributed in Italy by Detector Center of Cervia. It’s the entry-level machine from the French manufacturer XP that, till now, was somehow a little bit neglected in comparison to its “major brothers” GoldMaxx, Mito, G-Maxx and, obviously, top of the line DEUS machine.

As we speak, XP brand is usually tied to its medium-high and hi-end models and it’s easy to forget their lower end products, especially the “little one” ADX 150…

Finally I had the chance to complete my tests of the last Detech machine, the RELIC STRIKER.

Even though a new, top of the line model has been announced, the Detech CHASER, Relic Striker is still on top of the list of Detech’s “deep-seeking” catalog. This two word expression, in the treasure hunting jargon is related to specialized metal detectors, for hunting not so small and very deep targets, usually larger than a coin. In othedetech-relic-strikerr words, these machines are biased toward big targets (e.g. militaria and caches) at great depth.

Detech  Relic Striker is a single-frequency VLF/IB running at 4,8 kHz with a “monster” SEF (Symmetric Electromagnetic Field) 18”x15” coil. These simple informations, read by an experienced hunter, will be immediately recognized as a evident clue of a deep-seeking detector, high conductivity target oriented (copper, bronze, silver etc), great for not-so-tiny, very deep buried things and especially in highly mineralized soils.

Garrett Pro-Pointer AT: A.mazing T.echnology!

As announced last week, Securitaly (one of the official Italian Garrett’s distributors), kindly sent us a sample of the new  pinpointer made by Garrett Metal Detectors: the Pro-Pointer AT.

Compared to its predecessor, named Pro-Pointer, that had an incredible best-selling success, this new model is not only different in color, with an ultravisible orange, but it also introduced new exciting features that, in my humble opinion, could not be missed in a top of the line device like this.

Being lucky enough to own, with great satisfaction, the old Pro-Pointer too, I had the chance to test the “Old” vs. the “New”.

In arrivo il Minelab GPZ7000?

GPZ7000In questi giorni si sono rincorse numerose voci circa la prossima uscita di un nuovo modello dell’australiana Minelab. In numerosi forum internazionali sono circolate informazioni frammentarie ma sicuramente interessanti su questo detector. Iniziamo dal nome in codice, Jupiter (Giove) e dalla sigla che gli è stata assegnata, GPZ 7000. Chi conosce le macchine prospecting della Minelab avrà già intuito che probabilmente si tratterà di uno strumento orientato alla ricerca dell’oro nativo. Fin’ora infatti, tutte i modelli GP(qualcosa) come GPX4500, GPX4800 e GPX5000 sono state macchine Pulse Induction per uso specialistico nella ricerca dell’oro nativo.

Si è iniziato a parlare del GPZ7000 quando qualcuno, facendo ricerche nel sito dell FCC (Federal Communication Commission – l’agenzia federale americana che si occupa della certificazione dei prodotti che emettono radiofrequenze) ha trovato qualche documento dove si attestava, appunto, la richiesta di registrazione e certificazione FCC di questo nuovo modello.
Da qualche giorno però circola un’immagine pubblicitaria nel web, che vi riportiamo, dove (ammesso sia autentica) si può vedere il nuovo modello e leggere alcune caratteristiche.

Si tratta quindi di un modello pulse induction immergibile fino a 1 metro, dotato di connessione wireless per cuffie (e dati?), dotato anche di GPS e di sistema a menù grafici. Continue Reading

THEORY: Metal Detector, Oro e Prospecting…UPDATED!

Nell’introdurre il tema principale dell’articolo, per semplicità, iniziamo col distinguere quali possano essere i target d’oro rilevabili.

Possiamo facilmente distinguerli in OGGETTI NATURALI e OGGETTI ARTIFICIALI.

Tra i primi possono essere identificate ad esempio le pepite, le vene aurifere e i cosiddetti fiocchi d’oro, i secondi saranno tutti quegli oggetti creati dall’uomo con la lavorazione dell’oro (monete, gioielli etc).

Normalmente nel linguaggio gergale dei metal detectoristi, per definire la ricerca del primo tipo di target si preferisce usare il termine inglese PROSPECTING (in italiano PROSPEZIONE) che spesso ricorre tra le impostazioni di fabbrica di numerosi modelli di MD.

Quali sono le caratteristiche fisiche di questo prezioso metallo?

credoddmdisplayFor a long time I’ve desired to put my hands on a Nexus metal detector. This English brand, on the market since 2004, was always tied to high power products. Previous generation of Nexus detectors’ users always confirmed this axiom, with special highlight on their detection depth capabilities. Alas, the same customers were sometimes disappointed about difficulty to control stability of those machines, especially on the field. We could indicate the Nexus detectors as “Throughbred Stallions” that need to be tamed with patience and perseverance. Mr. Georgi Chaushev, chief designer and Nexus CEO, that we will soon interview, ante up with a new generation of even more poweful metal detectors with innovative and very interesting features.

INTERNATIONAL-MODS: E^5BOOSTER, enhance your pinpointer performances with a simple click!

Foreword by Leonardo/”Bodhi3″

As announced some days ago (LINK) , Sergio/”Xergix”, AMDTT senior member and electronic expert, just sent me his article on the E^5Booster (read it ‘E to the 5th Power’ Booster) project. I’m so happy Sergio decided to share his intelligent idea with all the blog readers who, I have no doubts, will really appreciate his work. I want to thank Sergio again for his excellent work and also I would like to thank Mauro/”Mauroki” for the extra photos and bench and field tests of the prototypes Have a nice reading!

AMD Tech Team Director
MODS: Project E^5Booster to enhance handheld pinpointer performance.
Project and Article by Sergio/”Xergix”. (c) 2014 for AMDTT
Extra photos and tests by Mauro/”Mauroki”

1. Introduction


The official E^5Booster Logo

Its a well known “trick”, in the detecting scene, that moving a small coin or any other small metal object closer to the base of the probe (Note by Bodhi3: the probe is something like an antenna, and it’s the sensitive part of the pinpointer) of any handheld pinpointer, you will have a sort of performance boost, in detecting distance/depth, on inspected buried targets. You will easily find some videos on Youtube about this trick and I will give you some links in the ending appendix to this article.

From the electronics point of view, the explanation is quite easy: the little coin just “tunes” the probe that fundamentally is a coil with a ferrite core inside. As well as with old radios that could be tuned by manipulating a coil with a ferromagnetic core (ferrite), the pinpointer probe can be “tuned” by placing a piece of metal at the coils end, gaining sensitivity.

Leonardo/”Bodhi3” Tech Note

By placing a ferromagnetic core inside a coil, the emitted electromagnetic field will be amplified. This is due to the increased electric inductance, since it is proportional not only to the coil windings number but also to the ferrite core magnetic permeability that is much greater than the one measured with air core.

Schermata 03-2456743 alle 15.29.22In this formula we can see how inductance “L” is proportional to the windings number “N”, to the nucleus area “A”, to its length “l” and the forementioned core magnetic permeability (greek letter Mu). In simple words, the iron core increases the electric inductance that will produce a more intense electromagnetic field.

2. How E^5Booster works?

The E^5Booster essentially is a virtual small coin but, compared to this one, has the great advantage it can be “activated” by just pressing a small button without the need of moving it. This will allow to easily fix it on the pinpointer in a stable way without any mechanical moving parts. Fundamentally the E^5Booster is just a coil and a mini button that closes the circuit when pressed. Let’s try to explain the technical difference between the “coin-trick” and the “coil-with-a-button” booster. From an electronics point of view, a coin is essentially comparable to a closed coil and could strongly interfere with a LC circuit (L=Inductance, C=Capacitance) as the pinpointer probe, in the same way a ring could do. You can use a common ring instead of a coin and the result will be the same: if the coil is “open” (read “interrupted”) won’t interfere with the probe, but if we shortcircuit it with a switch button, we will transform the coil in a sort of ring that could be compared to a coin. Easy, isn’t it?

3. Let’s do it!

Everything we need to produce an E^5Booster is a coil and a switch button: the more convenient coil shape is the planar one, since it can be easily adapted to any surface, rounded as Garrett’s Propointer, Minelab’s ProFinder, White’s TRX or flat ones as with DTS Sherlock or White’s Bullseye II. The switch button should be as small as possible and I suggest to use a 0,25 mm electric wire to produce the coil. It could be varnished or insulated. The coil I’ve made has 5 windings but the number is not critical. In the first prototypes (see photos) I used a small matrix board but it wasn’t flexible enough to be applied to the pinpointer in the right way.

So I had the idea to use something flexible and I’ve placed the coil and the switch button on a floppy plastic strip taken from a blister envelope. But I wasn’t satisfied enough. So I’ve transfered the circuit on a self-adhesive neoprene strip and the result is a flexible E^5Booster that could be easily applied on any pinpointer.

4. Let’s take a look at it


This is a magnified pic of the swich button: you can buy even smaller ones but I had a lot of them at home… so I saved some money…

Primo prototipo fatto su scheda millefori

The first prototybe on a small matrix board


5. How to apply the E^Booster to your pinpointer

Applying the Booster is very easy: you just need to place it on the base of the probe when the pinpointer is turned on. Then you slowly move it along the probe (toward its tip) keeping the switch button pressed until the pinpointer will start to beep. Then you just slightly move it back until the pinpointer beep won’t stop. That is the correct position!

You can now fix it with an adhesive tape (just the coil area, leave the miniswitch uncovered).

The E^5Booster, when the switch button is pressed, will almost allow to double the pinpointer sensitivity. I’ve, together with many friends, have done many tests on different models having really brilliant performances. Obviously, if you have a cheap pinpointer that can only detect things that are very very close (some cannot detect coins over 1 cm away!) the E^5Booster will maybe allow you to extend the sensitivity to 2 cm, but on good models that are able to detect a coin 3-4 cm away, the results will be amazing!

And think about it… No batteries…No special electronics…and soooo cheap and easy to be made!


Addendum by Mauro/”Mauroki”



Yesterday, during a hunt with my Spectra V3i, I had the chance to test the E^5Booster on the field on my Propointer. Its intuitive and easy use will enhance the already great performance of the Garrett pinpointer. You just need to press the mini-switch to detect targets at greater depths well over the original capability.


PRO: E^5Booster will almost double your pinpointer performance

CONS: If not correcty fixed or protected from moisture and mud, this tiny circuit could be easily lost or have some malfunctions.

I think the perfect solutions could be, and I know that Sergio is already working at it, to have the E^5Booster in a neoprene ring that could be fitted around the Propointer, with a well protected and waterproofed mini-switch. Mmmm… I think manufacturers should work on it. Don’t you agree?

Foreword by Leonardo/”Bodhi3″ (Director AMD Tech Team)

telecomandoEven if today two active AMDTT members are happy and proud owners of XP DEUS, our group was sometimes criticized for not giving enough space to the French manufacturer’s machines. Actually, in addition to the interesting article written by Alessandro/”Supermetalsandro that let him being awarded with our AAC prize in 2013 (see this LINK), we have analysed XP and DEUS machines more than one time with the exclusive interview to its founder and chief engineer Alain Loubet (in dual language Italian and English! LINK1 + LINK2), with the nice article by Sergio/”Xergix” on the DEUS “secret” features introduced since firmware 2.0 (LINK) and lately with a full review of Andy Sabisch “The DEUS Handbook” (LINK).

Now it’s the time to talk about one of the most amazing new accessory produced by XP for their top-of-the-line machine: a new 11″ DD coil.
Lot of users often complained about the small size of the stock coil (9″ DD) and about the excessive weight of the 11″x13″ DD spare coil.
Alain and his staff, as usual, have listened to the worldwide users’ requests and put themselves to work to manufacture what was really desired by many.

“Voilà”… Here it comes a 11” DD round coil!

Almost as light as the stock 9″ coil and… more performing!
After being informed of the existance of this new coil, I’ve immediately sent a email to Monsieur Loubet who, very kindly, after a very few days, sent us a brand new sample of the coil. Obviously I forwarded it into Sergio/”Xergix”‘s wise hands. He, helped by the precious support of Gianni/”Linux-Ubuntu”, immediately started a very rigorous series of  tests and analysis.

I won’t bother you anymore… Have a nice reading!

Piastra_28Finally Xplorer has launched on the market a so long awaited 11″ DD coil, a size that has become a sort of de facto standard on many hi-end detectors.

piastra_grande_deusWhen the 11″x13″ DD was introduced, most of the users were very happy for its enhanced depth but, on the other side, they were also disappointed by its excessive weight that unbalanced a detector who has in its light weight one of the biggest assets. Since then, a big demand of a new, somehow “intermediate” coil, grew up.

Xplorer, who is very famous worldwide to listen carefully to its customers’ desires, fulfilled this request in a very brilliant way!
They produced a nice 11″ coil (stem and fixing kit are included), weighting just 458 grams (including coil cover), exactly just about 15 grams more than the stock 9″ coil. Amazing, isn’t it?
Probably this will be the most appreciated feature since the metal will stay balanced and, I could confirm it since now, it allows users to hunt for hours without any arm fatigue. The bigger size, naturally, gives a greater soil cover and promises to bring an enhancement in depth compared to the other 2 coils.

Evaluating depth enhancements is always difficult and critical since too many variables must be faced. The easiest way should be doing some air test but, a part from being personally against those kind of not so reliable test method, it implies the lack of soil that surrounds the examined target and everybody knows the importance of this key factor during technical tests.


Weight in grams

Test Bed

With the cooperation of Gianni/”Linux-Ubuntu, we prepared a testbed to allow a first performance comparison between the new 11″ and the stock 9″ coil.

The ideal soil conditions were found in a olive tree grove that featured a nice vertical ground  cut without any containment wall. This allowed us to drill some holes, with a powerful battery drill, on the vertical face, placed at 14.5, 16 and 19 cm from the horizontal plane. As reference target, we used a bronze coin sized 22 mm fixed on the top of a flat wood stick that could be inserted and removed in and out the holes.

For our tests, we used two DEUS updated with firmware 3.2. To avoid differences, all the tests were made with the three most performing settings: Mito, DEUS Fast and Relic, without any setting modification, just turning on the machine, and ground balancing it over the soil (both machine measured a mineralization level of 72).

It would sound obvious to you that with those settings the DEUS is not at its maximum and we cannot demand spectacular performances; We agreed to keep these settings to keep the machines’ stability as much as we could. Also, we have choosen those particular depth measures (14.5, 16 and 19 cm) in order to have a comparable reference when testing the two coils.

General results show an advantage of the 11″ coil of about 3 (three) centimetres (1.18 inches) over the 9″ one. It may seem a little difference, but, in the analysed conditions, it’s a very good performance result.

We also made some target separation tests and, as we’ve being expecting, the 9″ coil showed up a little better performance than the 11″ one. You know… the bigger the coil…the less target separation precision you will have…


Some of these tests were recorded on a series of video we’ve uploaded on our YouTube channel . You could see them here (LINK)

Beach Test

The second test session was performed on a local beach. This time I pushed the machine a little bit to evaluate depth maximum limits. To place targets in position, we used a PVC pipe diagonally buried (45° degrees) in the sand. Then we used a second internal pipe marked with centimeters notches with a target holder on one end. This method allowed us obtain precise measurements of targets’ depth.

In these conditions, performance differences grew up and we measured a gap of about 5 cm (2 inches) between the 9″ and the 11″. The same 22mm bronze coin (used in the previous field tests) was now detected at about 33 cm (13 Inches) with a “diggable” sound

Tech Analysis

Strongly encouraged (Note by Bodhi3: You could tell “stressed to death” 😀) by Leonardo/”Bodhi3”,  I wanted to go into a deeper tech analysis.

My idea was to try to “visualize” the electromagnetic field shape, emitted from the coils. Obviously, with my lab instruments, I couldn’t aspire to high precision but, honestly, I think my experiments could give a quite reliable scientific representation of reality.

The analysis I performed, derived from my radio-amateur background (but also very common in other electronics measurements fields), was about measuring the electromagnetic field intensity emitted by the coil. I’ve thought the best way was to place a sort of “antenna” in front of the coil and to do a kind of horizontal/vertical “scanning” reading the values on a oscilloscope. My antenna was a Shure professional high sensitivity dynamic microphone (20-20.000hz frequency response) tied to a Fluke 123 portable oscilloscope.

The scanning steps were 2cm (about 0,8 inches) horizontally and the distance from the coil was exactly 5 cm (about 2 inches): so we had 150 measurements for the 11″ and 114 for the 9″ coil. They are a not large but sufficient sample to have a quite reliable analysis.

The results, as shown in the 3D postprocessing graphs, showed up a clear evidence that a different EM intensity diameter do exists: the 9″ has a more concentrated emission while the 11″ coil tend to have a wider pattern. Please note a peculiar dip of the signal toward the middle of the coil. My hypothesis on that anomaly is tied to a probable interference of the built in battery that is placed in the spoke where resides the transmit coil.

Bodhi3’s Tech Note: By carefully examining the electromagnetic patterns, you may be convinced that the 9″ coil, especially in the middle zone, could have a stronger intensity that could contradict field tests where the 11″ reaches better depths. One possible explication of this apparent inconsistency could be related to a better “nulling” between the TX and RX coils that lead to a much cleaner detected signal (lower S/N ratio) that allows a more efficient identification analysis even on very deep and weak targets.

I think it’s also very interesting to focus on the difference between the two coils (RX and TX) areas and the overlap point (where you can notice a signal nulling) and the maximum sensitivity area.

To perform a complete analysis, I would have had the chance to also make some measurements on the 11″x13″ coil but the one I had was not updated to 3.2 firmware release. As soon as I will upgrade it, I will repeat the measurement for my own curiousity.


Some targets found with the new 11" coil

Some targets found with the new 11″ coil

At the end of my analysis I can boldly state that true qualities of the new 11″ coil could be really appreciated on the field: first of all, its light weight, then a precise accuracy in target pinpointing and, with a good setting, you can gain up to 5 cm (2 inches) more depth compared to the stock 9″ coil. In real search I had the chance to compare the new coil with my mates’s DEUS mounting a 11″x13″. The new 11″ is definitely lighter and have almost the same excellent performance of the bigger one. VDIs were always coherent and only on few cases the 11″ was unable to show VDI but anyway it allowed to produce a solid and diggable audio tone.



This coil, without any doubt, brings the machine to a higher level and, I’m sure of this, it will be the perfect substitute of the stock coil for any demanding hunter. I can also add that, with the introduction of this new coil, XPlorer almost completed the coil set to face almost any possible request but I’m also sure that the French manufacturer will continue to surprise us with new innovative and amazing projects.



Note by Bodhi3: If I could find a single, but unfortunately not negligible, defect: the price… It is now sold at about 360 Euro (including VAT). We hope that the price will fall down as soon as possible allowing more and more people to buy this awesome coil without particular sacrifice.

TEST: Pala da mare Predator 2.0


Mauro/”Mauroki”, l’ormai conosciutissimo vice-direttore di AMDTT, sta accumulando nel tempo un bagaglio davvero importante di esperienza sugli attrezzi da scavo utilizzati nell’ambito del detecting terrestre e marino. E’ stato infatti autore di numerosi articoli su piccozze, digger, sestole e pale da mare. Oggi ci parlerà proprio di uno splendido modello di quest’ultima tipologia di strumenti da scavo: la pala Predator 2.0. Si tratta di un prodotto artigianale ma di livello qualitativo assolutamente al top di categoria.
Vi lascio, da buon “terrestre”, a chi ne sa molto più di me… Buona lettura!

Pala Predator 2.0

Markwollas, costruttore della Predator 2.0

Durante il mio continuo provare, testare e “combinar casini”, mi sono trovato recentemente a girovagare nel forum Romagna Metal Detector (LINK). Da un po’ di tempo avevo notato le pale create da un utente del forum che usa il nickname Markwollas. Negli intenti del costruttore, le sue produzioni si contrapponevano a quelle di un’altro celebre costruttore dell’Europa dell’Est. La gentilezza e il modo con cui entrava nelle varie discussioni mi avevano convinto a chiedere un preventivo per una pala da affiancare alla mia che, seppur valida, iniziava ad avere alcuni segni di cedimento. Tra le varie pale che Mark propone, quella che più si addiceva all’uso che gli volevo destinare era la Predator 2.0.

Dopo alcuni contatti in privato per definire alcune personalizzazioni che è possibile richiedere, ho dato l’OK e dopo appena due giorni mi è arrivato a casa un pacco imballato in modo impeccabile e molto professionale . Una volta aperto ho potuto apprezzare a pieno i tanti pregi dell’attrezzo che qui vi vado a sintetizzare.

foto 1

La pala pesa 1,3 kg, ed è costruita con acciaio INOX 316 dello spessore di 1,5 mm. Le parti di cui è composta e i fori, sono stati eseguiti con taglio Laser . Le saldature sono eseguite a TIG (Nota di Bodhi3: E’ un tipo di saldatura di elevata qualità che richiede l’utilizzo di apparecchiature professionali da parte di personale specializzato. Vedi WIKIPEDIA). Come se non bastasse, la pala viene trattata con micropallinatura (sabbiata) con polvere di vetro che rende esteticamente uniforme tutto il corpo.

2014-01-08 15.07.03La forma della pala è stata studiata con meticolosità dal costruttore e devo dire che è veramente ben riuscita. Oltre ad un estetica gradevole l’attrezzo presenta tutti gli accorgimenti che la fanno essere una super pala !!! Niente è lasciato al caso. La foratura del corpo è fatta con fori di 8mm, mentre il fondo e stato forato con buchi di 6 mm .

Questo accorgimento permette un ottimo drenaggio e consente di poter setacciare meglio oggetti di piccole dimensioni, che con fori sul fondo più grandi rischierebbero di ricadere in acqua, causando non poche arrabbiature al cercatore . La piccola “costola” anti-schiacciamento posta nel retro della pala, dal lato interno,  oltre ad irrigidire il fondello funziona anche da “rompizolla” favorendo l’operazione di stacciatura .

2014-01-08 15.07.41L’attacco per il palo è realizzato con un tubo (diametro interno 35 mm) sul quale vengono inserite due farfalle che consentono un sicuro e rapido bloccaggio. L’angolo di attacco dell’asta-manico permette un comodo inserimento nella sabbia e la successiva estrazione senza fuoriuscita laterale

 di materiale.  Io personalmente prediligo i pali da badile in vetroresina perché galleggiano, sono elastici e impermeabili. Mark mi ha proposto quindi di adattare il tubo per le mie esigenze …. niente di meglio. Il retro della pala ha una sorta di piegatura  che offre un comodo appoggio per il piede facilitando il suo inserimento anche nella sabbia più dura che si possa trovare. In realtà, la geometria della pala e così ben riuscita che, su sabbia mediamente morbida, può essere fatta sprofondare foto2anche solo facendola opportunamente vibrare.  Una volta conficcata nell’arenile, appena si inizia a sollevare, la pala inizia subito a drenare sabbia e il “manichetto” che Mark fornisce insieme alla pala, agevola e non da poco l’estrazione e la conseguente setacciatura della sabbia .

Considerazioni finali 

Si tratta di un ottimo attrezzo, veramente resistente. La sto utilizzando da settembre e non sono riuscito nemmeno a scalfirla e vi assicuro che ci ho messo tutto il mio impegno !
Complessivamente la ritengo una pala superiore a qualsiasi attrezzo che ho visto in rete sia di costruttore europeo che USA.

Se proprio vogliamo trovarle dei difetti, o meglio, suggerire alcune piccole migliorie, io proporrei foratura a foro rettangolare (ma mi rendo conto che realizzarli complicherebbe la vita non poco al costruttore), alzerei i bordi laterali di un cm e farei un piccolo foro sul tubo “porta palo” per il drenaggio dell’acqua . Per il resto, mi fa piacere ribadirlo, la ritengo il Top per la ricerca in mare, e la consiglio a tutti coloro che cercano un attrezzo di alta qualità e dal prezzo più che interessante.

Che dire quando gli italiani si mettono a fare qualcosa non li batte nessuno !!!
