    Haha, if you believe that there is a guy willing to sell you a bridge in up state NY. Believe none of what you hear and only half of what you see. I’m sure everyone has heard that adage.

    Well I've not been a member here long enough to tell you what I think of that 🤪 but my post above was just word for word what the dealer told me this afternoon when she called me on the phone.

    Hoping it'll get resolved soon as they rang to take payment as soon as they thought they were on the way to the store, and this delay has come along unexpectedly.

    Oh, that has got to suck!  Customs must think there are drugs in the waterproof control module.  LOL  That's probably what's going on here, too.  Are they taking the Manticores apart looking for drugs?  :unsure:

    So, little did Minelab know when they named the detector, Manticore, that they were giving it a name used by drug dealers for their product?

    I've noticed on the TnSharpShooter videos that the name, Manticore, has been removed from his control module face.  I wonder if that had something to do with getting it through customs without scrutiny.

    The tester preproduction units didn’t have the final printing on the module which would explain that. Or to fool the drug dogs at the border one of the two 😝

  3. Back on the manticore deliveries - just had a call from my UK dealer and apparently the whole shipment of manticores are stuck at customs being investigated/checked. The shipment of 7/900s which was sent later has landed in the uk fine though, seems the new product name or whatever has flagged it for additional checks 😞

    Thank you for explaining, what you said makes sense with positioning on the screen depends on their metallic composition. I have seen videos where objects bigger than coins and rings had a bigger blob on the screen and I think that would be helpful knowing its less likely to be a good target.

    There seems to be a lot to it as well as purely composition, including orientation in the ground (on an angle can make a more 'smeared' TT shape) and anything irregularly-shaped such as trash or a broken item which would always give a jumpy/erratic TID on a detector will also have a larger/more irregular shaped TT blob.  Some good info in the manual PDF which shows some bottle cap examples and how they can create various TT blobs 🙂

    My last comment was misleading. The shapes of the pull tab and gold ring wont tell me its those objects but rather there is a difference between the two, enough for me whether to dig or not. If I'm on the beach and cherry picking targets, I could ignore odd shapes which are more likely to be objects other than coins and rings.

    On that we're agreed - anything that helps discern the differences between what's down there is a help.  Tones will give much of the same data with jumpy/fuzzy signals but I for one am quite a visual person so the TT screen should hopefully be a help.

    Guess we'll find out soon but it'll be practice practice practice for a good old while before ignoring stuff becomes commonplace 🙂

    I'm sure what you are getting at?. What you mentioned doesn't change my observation that the pull tab and gold ring were of different shapes on the screen. My comments were based on whether target trace gave additional infomation, compared to numbers and audio on making a decision whether to dig or not. It allows me to distinguish between a pull tab and gold ring.

    I'm just pointing out that TT will not "show the shape of an object" as you stated which is being misquoted in a few places.

    Objects will have different shapes (and positions) on the TT screen depending on their metallic composition, but that shape won't necessarily be that of the object being detected - and if it does it's more a coincidence than by design.

    The target trace screen shows the shape of an object which is extra information. I've seen a video where a gold ring is displayed on the screen as a round blob and a pull tab showing as slightly elongated shape, something numbers or audio tones can't do.

    No it doesn't.  An elongated/irregularly shaped plot MAY correlate with an oddly shaped object, but it's just the plot of its 'jumpy' TIDs plus its level of ferrousness vs conductivity.

    Have a read of this page on the main MC thread:

    Digalicious, here is a new video that provides a better understanding of how the Target Trace 2D screen presents various objects scanned.  It might help you answer some of your concerns.

     

    I think that'd have been a more useful video if he'd left the iron audio on throughout.  Interesting to see some of those traces though 👍

    So, your UK dealer has received his shipment of Manticores?  Or they are on the way from the UK distributor?  Do you know how many he received?

    They're in transit from distributor to the dealer, so they were ringing the folks on their preorder list to take pay with the intention of getting them back out the door the same day they come in.  

    I didn't ask how many they were getting but they confirmed I was in the first batch so likely to be one of the first UK customers in the wild to lay hands on one 🙂

  10. The site formatting gets messed up when you browse around via the navigation links (at least it does on my browser due to security controls), I recommend removing the s from https and the www. from the page address bar when you change pages, i.e. changing https://www.dankowski... to http://dankowski...

     

  11. I've set the cash aside so I'm pretty much at the "Shut up and take my money" stage in my Manticore adventure 😄

    Was out with the Nox at the weekend again and it's still a wonderful machine, picked up some tiny targets even in amongst the trash but would really benefit from a bit of better 'what's under the coil?' type discrimination.  I'm hoping the Manticore can help with that (and if it doesn't then it should be an easy flip to sell on and I'll go back to ol' faithful as if nothing ever happened 😛 )

  12. Not sure if this info has been shared yet, but taken from a post I've read elsewhere:

    "2D ID Mapping
    The CTX3030 from Minelab, is a highly-regarded coin and treasure detector, maintaining its status as a high-performance metal detector for 10-years now. And one of the features that made this machine so popular is its visual XY, 2D presentation of targets. The FeCo system, or Ferrous and Conductivity to the uninitiated visually plotted the two different attributes on display, allowing the detectorists to analyse and decide on what a target could be due to the plotting position of a target. Very cool! However, Minelab have taken this system and made it even more sophisticated. The Manticore has a new 2D mapping system which has a horizontal line running through its centre. Targets which are plotted along this central line are non ferrous and the further they stray from it above or below mean they contain a higher iron content. That covers the targets position along the y axis, and this leaves the left to right, or x position which then covers conductivity, with low conductors on the left and high conductors on the right.

    But here’s where it reaches the next level, the shape of the indicator on the map also related to the target. A solid, concise object, like a coin will most likely be represented as a nice, clean dot on the screen, whereas a more erratic object will be represented as a more irregular shape. For example; a silver coin would show up along the centre line, as a tight dot, and towards the right side of the screen (due to its high conductivity), whereas a small iron nail would show up far from the centre line, as an irregular shape, and further towards the left of the screen (due to its lower conductivity). That’s a hell of a lot of information about a target before you even dig it. We will say though, it’s not going to be perfect every time, obviously environmental factors and target position will play a role in determining how precise signals are displayed."
     

    Target Separation
    Here’s something we have to tell you, as it blew our mind. Ensure you’ve read the above about 2D ID mapping to fully understand this bit.

    Craig Allison met Mark Lawrie, The Chief Engineer at Minelab and this demonstrated how good the Manticore is at target separation. Mark first showed us how the Manticore would communicate a hammered coin. He waived it left to right above the coil, and sure enough as described previously we saw a nice, tight dot, on the centre line of the Manticore display. What was really impressive however was when Mark added a second target into the mix. On the second demonstration Mark waived the hammered coin again, but also a large piece of lead with his other hand, both passing from left to right over the coil. We once again saw the hammered coin’s dot in the same place, but now saw a larger, messy splodge in the far-left corner of the screen. This easily illustrated that two targets were present, and that the Manticore is easily able to separate targets and reduce masking. This is a real game changer in terms of knowing when to dig, particularly in trashy sites like Roman settlements where lots of iron may be present and would therefore sometimes cause detectorists to doubt signals and decide not to dig.

    Is the 2D feature suppose to outline the physical shape of a target?

    I was under the impression it is more of a plot based on conductivity over several passes of the coil. Akin to the Whites Spectrograph.

    Garrett had size imaging 20+ years ago but it used a special coil. A good ear can do that on a modern detector by the proportional audio response.

    What I'd seen so far suggests that the 2D screen is meant to show what sort of ferrous vs conductivity the target has, with the top/bottom being to allow you to see what type of ferrous target it is (small nails vs deep iron) and the middle of the screen being less/non-ferrous 'good' targets.  

    The cleaner/purer the signal then the tighter the blob on the screen.  

    In a few of the videos shown though the demonstrated 'good' target has been something like a silver coin which shows a nice tight round blob, so I guess some folk have taken that to mean it shows target shape.  Likewise a rusty nail with a mix of solid iron and rusty bits has a more stretched TID range and has been showing on the demos as an elongated blob.

    I'm not expecting any real-world shape indicator from the Manticore myself.
