Pocket Metal Detector Picosens

Recommended Posts

Hi All,

Today I found this "introduction" of a mini/pocket md on the YT channel of "Sondelsüchtig". 

A "new type of" metaldetectorsensor/coil with a smartphone app/screen.....  Is this the future? Don't know, but I thought some of you might find it interesting to view.

It is in german, but the video "speaks" for itself.  Sondelsüchtig means "addicted to detecting".  And € 399,00 = us$ 448,60. "Handy" is a smartphone.

The YT link to Stephan's/Sondelsüchtig's channel: https://youtu.be/B7XLdSk0guE

The basic idea is actually very old. One of my first detectors was a coil printed on a circuit board and a few components. You would take an AM radio and tune to a certain channel. A coin waved under the toy... and that is all it was... made a signal on the AM radio.

The XP Deus is proof an entire powerful metal detector can be built into a coil with a remote that actually is just a controller. All the heavy processing is done in the coil. The only reason we have not seen much of this with phones is the connection speed, but new phones with low latency connections will no doubt result in a very good detector... sooner or later... that uses a cell phone as a controller.

I don’t expect it much from the traditional manufacturers however as it gives them less to sell. XP really wants to sell you that controller. It will probably take a newer party to make this really happen the way it needs to be done. It really is inevitable.

My thoughts and some of the reasons I didn't buy an XP: 

EMI with wireless everything is an issue where I live and detect. Even running my pinpointer on full sensitivity causes it to fault in some areas.

Putting all the guts into the coil makes the coils too expensive and limit the options other manufacturers have with choices in sizes and even 3rd party brands ie Nel, Coiltek etc.

Display is too small. (in the case of using a cell phone then battery life is an issue)

XP specific having the coil battery in the lower shaft I assume limits how deep it can get wet.

I think it's a novel idea that needs much more refinement. If I were to have a dream machine I would put the brains in the shaft shielded from EMI with coils that snap in using the shaft as the conduit for the wires. Have the display that can used remotely or clip in for underwater use. Headphones should be the same unit with the ability to plug into the display box or upper shaft for undewater use or retract the cord and go wireless. And lastly all using a rechargeable battery system.

I think to properly critique the Deus, you really have to try one out to discover whether there are real shortfalls in the design/operation for your requirements.  In theory the wireless design may seem to some to be prone to EMI when really it isn't, my Explorer and Etrac with a wired connection were a lot worse in that department, especially around buried electrics and transformers.  The Deus is no different to other VLF detectors in that respect, with main EMI derived from using physically larger coils and lower frequencies rather than the actual wireless connection between components - can't say I have ever had an issue.  Even then you have multiple frequencies and offsets to chose from if EMI is prevalent on a specific frequency.

Despite the coils being expensive, combined with huge adjustability of the Deus they prove to be very flexible over different sites negating the requirement for several coils, the 11" and 9" is pretty much all I require.  Some other VLF's will require multiple coils due to the lack of inbuilt adjustments like recovery speed, where changing out the stock coil for a smaller one is the only choice for improving target separation, or if a larger coil is required for increased depth performance (ie. no ability to reduce the recovery speed).  Having to change out wired coils can also be a pain, on Deus it takes just seconds to just slide on a different coil, start it up and off you go.

The battery and connector in the lower shaft of the HF coils is waterproof, so no issues there with water ingress.

Initially I too thought the display was going to be hard to read due to the size, though that hasn't proved to be an issue when compared to other detectors I have used in the past.

I am sure the Deus and Orx are fantastic machines, just not a good upgrade for me as I tend to use more all terrain machines. I even looked at the Anfibio, Equinox and AT MAX. For any water hunting the XP machines fall short for my use unless I pick along the shoreline.

I really considered the Orx but the stock 9" coil is a little small and as soon as you go for the larger coil then the Equinox is more competitive and better performer in poor soil conditions where it is a true multi frequency.

XP has their niche and great innovations, just seem a little pricey when compared to the latest lineup of machines out there.

The Deus is one of my favorites and I still have mine although I dont use it as much as I did with the Nox being out. It is one of the best built detectors I've ever had the pleasure to use. It is not as effected by EMI as one might guess...the Nox suffers more in that regard. A month or so ago my buddy was using his Deus and Me the Nox and we were not far from some power lines and I had bad EMI problems. He got like 8 coins and I only got one or 2. The only thing I never liked about the Deus is the menu on the controller...we just never really clicked...I still find it confusing some times. The Nox is nice and simple.

I would have snagged the Orx but the biggest reason I didn't was it wasn't fully submersible as my AT is. I really liked the idea of the machine being so lite and ability to change frequencies. The stock 9" coil is also bit of a downside though probably a better choice for relic hunting in the woods. I tend to lean towards larger coils if possible.

I think an important point is just how flexible a cell phone or tablet based system is.  As a sometimes iOS programmer I am frustrated by the limited information displayed on my detectors.  There are wonderful things I could do if I could import data into one of my iOS devices.  As it is easy to import the audio, I am toying with what I might do with it including 3D maps, vertical profiles and trace stacking to reduce noise.  There are technical issues, but I think I could overcome some of them.  Maybe next winter.

I'm hoping to someday see a mainline detector with data-out streams.  I'll geek out if I do.

Not to go too off topic and not to make this about just XP but only using XP as an example since they seemed to have done this first in a production sense is having the brains in the coil only really adds to the cost of the coil. Any performance gains are probably negligible.

If my Tesoro dies then I will consider an Deus or Orx as machine wise they are more similar than an all terrain machine.

      What is this Deeptech VISTA X ???
    • By phrunt
      Well, after reading JP's review on the QED followed by Reg and Northeasts review and the occasional QED user popping up I decided it's time to get one.  I didn't need the full package and was on a budget so bought a new one but without the 11" coil it comes with, also with the different shaft more like my Gold Bug Pro shaft.  I'm quite used to that shaft style and like it.  I'm yet to get my wireless audio kit for it, I ordered the Quest Wirefree mate kit from Phase Technicial yesterday. It's meant to be good for the QED but I'll use it for my other detectors too, it can make any detector wireless using 2.4Ghz, nice fast audio.   Once that arrives I'll be completely wire free from my QED. 
      The QED feels so light, super easy to swing.  It's just using 2 x 18650 batteries so really there is just no weight to the detector at all, the only weight I notice is the coil.  I was surprised how small the control box is, it's tiny!

      On the floor next to it is my little Sony speaker, it's powered by 2 x AA batteries and makes the audio nice and loud on the QED until I get my wirefree kit and then I'll start using my Steelphase SP01 booster with a SPK08 GME like I use on my GPX, only difference is I won't be tethered to my detector.
      It was raining when it arrived so I played around inside with it.
      I fired it up and was surprised, even inside my house it was hardly bothered by EMI at all, I adjusted the Threshold B to suit the coil, simple to do, move the numbers down until it makes noise, move it up until it makes noise, in my case down went to 48, up went to 58, here you can either favour smaller targets by going to say 49 or 50 or you can favour larger targets by going to 56 or 57, or you can leave it smack in the middle at 53 for an even balance between both.   That's why understanding anyway, I'd hope some experienced QED user would correct me if I'm wrong.   As our gold is mostly small and the only gold I have to test it with is small I settled on 50.
      I then moved my gain up to 10 (the maximum) and it was running nicely, even inside my house there was very little false signals.
      The QED has a mode as well, between 1 and 16, 1 for mild ground and is more sensitive to small gold, up to 15 for mineralised ground, and 16 for the beach.   I of course wanted to be in 1.
      Still the QED was running pretty quiet inside my house, very little false signals at all,  my house is full of EMI, a very powerful long range WIFI router and all the usuals, plus my house is only a short distance to high voltage power lines coming from some Windmills.  To be able to run the QED maxed out inside with minimal issues shocked me.
      I tested my various coils on it including the 12x6" X-coil which ran like a dream, then the Coiltek Joey 10x5, and the same settings as the X-coil and worked just fine.  Then the Nugget Finder EVO 14x9 was installed, I had to adjust my Threshold-B after installing this coil, so moving the numbers down till noise, then up till noise then picking the spot you want it... no big deal, takes about 20 seconds even for a first time user.
      The EVO had a bit more falsing inside due to it's size I guess, lowering the gain down to 7 from 10 fixed it up, tested with a shotgun pellet and the depth difference from gain of 10 to gain of 7 was hardly noticeable.   The other thing i tried was moving off Mode 1 onto Mode 5 and then I was able to run at gain of 10 again with very minimal falsing.  I was getting between 1 and around 2 inches on shotgun pellets with all coils I tested in an air test.
      The rain stopped so I headed away from home to a more remote location (3 minutes drive) away from the EMI of my house and put on the X-coil.  Now it was completely silent, not a peep from the detector unless I went over a target.  I ran on it on the default threshold which is silent, I turned the threshold up and found I had a nice smooth threshold but I was happy with it on silent, It was like using my Gold Monster, only noise if there is a target,  On my basic tests it didn't seem to hinder it's performance running silently but I'll test further in the coming days.
      The QED has a default ground balance of 100, I didn't need to do a ground balance, I could raise and lower my coil all I wanted with no noise, Auto ground balance didn't do anything as it was already balanced, I ended up lowering my ground balance to 70 manually and it was still silent pumping my coil so I just left it there, I tried as low as 50 but noise started to come in then so 70 seemed a good spot.  This is where I will differ from a lot of people so take into account my ground is VERY MILD so my results will likely be different to someone in higher mineralisation.
      I tested over various nugget sizes and was pretty amazed by the results, it felt like I was using the Gold Monster, very sensitive to small gold, I was detecting bits as small as 0.02 of a gram, 0.04 of a gram was giving me over an inch.  A shotgun pellet was also over an inch, more likely 1.5 to 2 inches.  I wasn't accurately measuring of course.
      The small gold ability of the X-coil on it to me seems far better than on my GPX 4500.
      I could move around the ground and never get any false signals, nothing caused me issues, if there was a noise it was a target.  This was pretty good as I was running it in the settings I believe are maxing it out.  I might be wrong but that's how I understand it being a first time user.  To me it feels like a Pulse Induction Gold Monster 1000.
      The only negative I have is the audio without some form of amplification is too low for my liking, I like loud audio.  With the SP01 booster it's brilliant, with my Koss UR30 headphones plugged in directly  I found it was pretty quiet, although I'd never use them on it anyway as I want wireless.  Once I get my Quest Wirefree kit I am sure it will be resolved as that's a powered unit, I think anything powered will work well on it but non-powered speakers/headphones will be too quiet for me.  My little AA battery powered Sony speaker works great on it.
      Obviously I've got a lot more to learn and a lot more hours on it to be able to even consider leaving a review but these are my first impressions.  All the outdoor testing was done with my 12x6" X-coil, I hope the weather is good to try my NF 14x9 EVO and Coiltek 10x5 Joey on it tomorrow.  I hope this post makes sense...
      So far I'm very happy with my purchase.

      Hello all.  I was wondering if it's possible to customize the tones on the VX3.  I know you can assign tones to all the vdi #s on the V3i and even change the tone pitch on the XLT and DFX, but I did not see where you can alter the tones on the VX3.  Maybe i missed it in the manual.  Does anyone know?  thanks.
