  1. Thanks Phrunt. Seems to be different variations (bundle, spiral, spiral/bundle, GPZ modded) of these coils around & some don't appear to know what variation they've even purchased? Would be interested in one for the GPX but would also like to see some more Aussie feedback & manufacturer transparency around what your purchasing etc.
  2. Possibly QED with PI X coil? Any news on the PI coils being sold/used in Australia. I had seen the prototypes did have issues here? Are the PI coils just another spiral wound option or different again?
  3. Minelab coils have 3 years warranty. Same same though - a lot would now be close to or out of warranty. Just something I haven't seen, what is the X coil warranty & is it return to Russia or return to Aussie distributor?
  4. It's not all that uncommon Phrunt. Most detectorists that use both VLF & PI detectors will have similar stories. It's a known fact that a higher frequency VLF (LF) like Whites GMT, Gold Bug, Gold Monster etc. will see some gold better than a PI will. I had a small bit of gold that my GPX5000 (or a mates) couldn't see even on the coil but my Whites GMT picked it up no worries. At the time I was a bit perplexed as I had only recently shelled out for the then top of the range 5k. I soon found there was quite a few examples of this around & mainly on specimens where the gold was finely disseminated through the host rock or small prickly bits. I tend to agree with Jason above that your bit may have fractures/breaks in the gold making it a difficult piece for a PI. The QED likely gets it due to the very low pulse delay utilised in mode 1. From memory it is somewhere in the range of ~7us - as a comparison the lowest pulse delay on Whites TDI Oz Pro was 10us. I believe there was a TDI mod for more sensitivity down to 8us. Of course there is more to the QED than just mode but a short pulse delay on those types of gold would be a big factor. Be interesting to see if kiwijw's SDC can see it at all as well as his GPZ.
  5. I can't see anything on the ACMA website where the use of ferrites is a requirement. They do recommend the use of both internal ferrite beads & RF chokes (or filters) on external leads made from ferrite material - like the clip on ferrites used on coil cables - for equipment that is having RF transmission interference issues. Given that detectors can both emit & receive RF then they probably recommend ferrites as being a good preventative idea?
  6. I might be corrected here but I'm pretty sure when I got the QED wayback then I was trying to find out more about the coil cable ferrites & came across some info that during the ACMA (Australian Communications & Media Authority) accreditation they recommended that they are fitted? In my experience with these Government Authorities if they recommend something it's usually a good idea to do it or at least recommend it yourself. They like that but it was a while ago so they may have also made it a requirement of accreditation? I used coils on the QED both with & without the ferrite. Couldn't really tell much if any difference but didn't do comprehensive testing + usually tend to stay away from EMI sources/interference as a habit. In saying that they certainly do have an effect on some things. I had fitted a new set of LED driving lights to my 4wd but when switching them on couldn't listen to the local AM station coming home from work (I like the 5am fishing report on the AM station). The reception is poor/already minor static out there on the AM station but the lights made it a lot worse. Reception on the FM station is strong & it wasn't affected by the lights at all? Just for laughs I put ferrites I'd purchased for QED coils on my driving light cables. I can now listen to the AM station in poor reception areas (still some static but tolerable vs previously not tolerable) - until then I was fairly sceptical that they did anything to be honest. I now think they could have some positive effect in higher EMI/interference areas & could even be worth trying with coils on the GPX? More likely though that they are dampening the effects of the lights not restricting the incoming interference to the radio.
  7. Looks like it will be a top unit in the mild NZ ground Simon! 👍
  8. Somehow I don't think an X coil is going to improve your score against KJW Phrunt. You've got good coils already. 😉
  9. That "Minelab Vanquish" video isn't on Minelabs proper YouTube channel so I'll take it with a grain of salt https://www.youtube.com/user/MinelabDetecting
  10. True - I was just pointing out that whatever it is it didn't make the half yearly report but a countermine detector release did. I'm thinking it's not something that will interest most that already own topline machines? MultiIQ but possibly cheaper version of Equinox? All speculation until Minelab release something factual.
  11. There were no gold/recreational detectors announced in the Codan half yearly report issued 20th February 2019. There was however a new countermine detector announced: "After two years of development, Minelab’s new countermine dual-sensing detector is in final testing and will be released in this half. This detector was partially funded by the Australian government and combines ground-penetrating radar with simultaneous multi-frequency metal detection in a compact, lightweight, high-performance dual-technology detector. It will be the best dual-sensing detector on the market." Been in development since around 2016.
  12. In my experience/opinion the QED will behave like that for 2 reasons - 1. Because your ground balance isn't right (assuming other things like bias, Threshold A, gain & mode are set for the area/coil etc.) 2. The ground is very mineralised & upsets it (+ other machines). The only reason I commented was because it has also been my experience that more mineralised ground has balanced at a higher number for me with the QED i.e. 110+ vs. 89 in the video. That isn't to say that the operator doesn't have it set up as required but it was only my opinion that it may not have been 100% due to the low ground balance number - it wasn't my intention to pick holes in the video or the QED. Infact my intention was to indicate that it can & does operate better than any video will likely prove or disprove. Perhaps some reactive ground does indeed balance to lower numbers but it's not something I've experienced myself with my QED. Another QED user has previously told me he gets low (in the 80's) ground balance numbers in his area on ground he describes as high mineralisation which is several hundred kilometres from my area so it is feasible just not something I've experienced or seen before. Hope that clears it up a bit.
  13. From what I can gather the PL2 updates haven't changed a lot, if any, since the video apart from the addition of the beach mode. They should operate fairly similarly. The reason for my recent updates was mainly to change the outlay of the detector so software was done while there. There's no constant need to be sending it back/forth for upgrades phrunt - it would only be ever required if some improvement were made that you just had to have. I'm no operational expert but to me the ground balance is fairly obviously not 100% although the operator in the vid may prefer it like that? I've never been a bloke to shoot a video & probably never will be but would try to offer any operating advice to the best of my knowledge that I could. Goldenoldie I couldn't really careless what anyone thinks of the QED or how it operates but as a user for close to a year felt I may be able to add to this QED topic. Why are you here??
  14. I don't know that the above video is a good representation of the QED? To me it's still sounding off on the "hot patch" even after adjustment (just before he says thats ground noise then there's a cut in the video), although it is diminished in broadness it's still there. It then continues to make spurious noises as he moves forward after going back to the original balance of 89. My opinion is it doesn't sound very well ground balanced for that area. Mine is a PL2 & has been recently fully upgraded & includes the new beach mode. There are only a few areas, even after the updates, where I've been able to get a ground balance figure below 100 (lowest 92 from memory) & these were fairly mild spots so I think 89 for what he says is hot ground might be too low? When ground balanced well the "trick" of moving the balance +/- 4 depending on whether it's a rising or falling signal does work well but in some very variable ground can become a chore or leave you wondering if the signal only diminishes & doesn't dissappear - upside is when I've dug these any diminishing or dissappearing signals have been ground not targets so it is worth the effort. I've witnessed first hand a GPX pick up a "signal" that I couldn't get with the QED - turned out to be ground noise so getting the essentially manually balanced QED spot on to the ground conditions is very doable. Kiwijw - my QED is numbered just over 500 & getting close to 12 months old. I did see somewhere a user had said theirs was numbered in the 600's so if they are numbered in order of manufacture there is getting to be a few around now. It would be interesting to get one in NZ to see what you guys think of it in your ground. My thoughts are it would be very good & being so lightweight ideal for the mountainous country. They find gold but like any detector you need to swing over it in order to find it.
  15. I do (but not the reviews). There are a heap of fakes on the Australian used market & despite attempts to educate people some still believe that there's a chance these counterfeits will work properly + they'll get a bargain. Once they work out all is not well with their bargain they try to on sell it. If buying used on eBay, Gumtree etc. always check ALL details not just the serial number (many fakes have duplicated correct numbers on them). Also ask about time/date of purchase, place of purchase & double check ALL info with Minelab. Best bet if unsure is to buy from an authorised dealer who will also offer some shop warranty on a used machine.
