  1. You can experience the latency if you plug one earphone into Nox and other into the WM08. Personally, I did not experience any problems with the WM08, except that I do prefer how direct connection sounds, as in, quality wise it is cleaner, more analog kinda sounding to me. I detect wired for this reason. The other reason is, when wired, I do have to remove headphones when digging out the target, which allows my head and ears to rest a little and appreciate what is happening around me. Just overall experience is less tiring and more enjoyable this way I find. The other thing, I'm not sure what effect wireless transmission has on the machine itself - if you ever try to bring coil near wireless router, you'll see what I mean...
  2. It's probably correct to assume there are not 19 channels, but 19xFrequencies Nox operates in selected mode. As you may know, what we call channels are simply frequency offsets from base frequency. Nox operates at multiple frequencies, but offsets (channels) are the same? Say, if Nox worked at 5, 10, 15 khz simultaneously, channel 1 could be 5.1, 10.1, 15.1 khz and so on. What Nox does when 5.1 khz is noise free and 10.1 is full of it is hard to tell...
  3. Apologies. For some good reason ML decided to put a DC blocking capacitor on the output stage to drive the coil. As you may know, these age with time and may present an extra impedance on the signal path, potentially lowering coil emissions. How they degrade and when it becomes a problem is hard to say, but it is a gradual to a point. Can be 2000h, can be 20000h. It's Panasonic OSCON, it seems, they have in there, but not sure which series. They are highly regarded and reliable component. Potentially new Nox may outperform one few years old in some scenarios where raw power is needed. Driver is AO4882 if anyone is interested.
  4. Equinox coil driver is run through a DC blocking cap, which can potentially age and, perhaps, exhibit losses. It's a very good cap though.
  5. I find that Park1, as name also suggests, is a lot better in trashy ferrous environment, better at discriminating ferrous. Field1, I feel, is better where ground is cleaner and you don't expect ferrous targets to dominate. In other words, with Field1, I tend to dig a lot more iron, at least with 1.7.5 firmware.
  6. Perhaps a silly question, do MDs have to comply with any EMI restrictions? Any reason they emit similar amount of power? Looking at the EQX, it seems like it is working at about 70% of what power components could possibly handle.
  7. I've heated mine a little and bent to the size that works for me. 10 min job...
  8. Apologies for off topic a little, but, perhaps, related a little. Did anyone notice Nox performing different - "better" when left motionless on the ground for some time, coil face flat. It would be not first time I meet walkers while detecting and after having a few minute chat I find Nox starts picking up things a lot clearer suddenly. Is it just my mind having some rest or Nox performs some on the fly adaptations?
  9. Would be nice if they introduced menu items and modes back and forth buttons, bit annoying to loop through all modes and menus to come back to adjacent items. Say, to do Noise Cancel after GB needs lots of button clicking. S-shaft or off-center coil ears, and stronger ears too. Make more user friendly adjustable items scaling and ranges. Say, volume, sensitivity, etc, 0-10 (or 100), not 0-25. Who actually detects with sensitivity 0-10, why have this range at all. Perhaps have some sort of accelerometer to detect when detector is still (say, on the ground) while user is dealing with the find or locating an item, so it doesn't chatter or scream in PP mode during that time. Maybe reduce emissions and reception too during still time, to save battery, etc.
  10. Some sports energy gels packages give 1. But mostly 1 is coke in my area.
  11. My detecting buddy once asked me if he should get a coil cover for his Deus. He didn't realize he already had one 😀
  12. I bang mine now and then and thankful the cover is there. I look at the cover and see it has plenty of dings and scratches, so it does a good job. ML coils are not completely filled with epoxy, there are structural voids underneath that would collect dirt and would be hard to remove I think, and these some dirt can really upset how detector works. This plastic cover is transparent to the magnetic field, there is probably no gain to be had, besides some small weight off?
  13. Thank you for trying. That's strange, on both my laptops this is the path it places files. You can also try to access it by entering %localappdata% in Run menu (or Windows+R buttons), perhaps it is somewhere else.
  14. Apologies for a bit off topic. Was looking at minelab update utility, in fact, I may have them all, just out of curiousity. There will be lots of assumptions later. ML firmware binaries are embedded into single files, which are named same as their MD5 hash. 1.0.4 - file: ef4e7d9f630334e8d1a7d98860d488a1 - versions 1.5, 1.7.5 1.1.1 - same as 1.0.4, perhaps update to the utility only 2.0.1 - file: d950cbc77e6db16755d13f7fc04bc4d5 - versions 1.5, 1.7.5 and 2.1.12 3.0 - file: 50c28cc3311890dd718f2f64ea861f83 - all previous versions incl 3.1.3 Strangely enough, or maybe not, for example, same firmware 1.5 in binary looks different in all update utilities. Could be many reasons for it. But I am inclined to delete the folder below (on Windows) if you are rolling back and use earlier update utility (see above). <C>:\Users\<user>\AppData\Local\Minelab\Minelab Update Utility Their firmware config file indicates there may be 3 hardware revisions of both Nox 600 and 800, but they all receive same corresponding FW. May explain rather inconsistent Nox performance and user experience for different people. There is potentially a possibility to flash 600 with 800 firmware and other way around with some juggling with file content, file names and permissions. If I had 600, I would definitely exploit this. Question I wanted to ask, do both 600 and 800 users have the same warning message in the update log, on Windows: <C>:\Users\<user>\AppData\Local\Minelab\Minelab Update Utility\log_<N> "MLB "<path>" block 3 is not of the required type "PTPSCBM1"" Looks like PTPSCBM1 is only applicable to Nox 600 and its firmware. On Nox 800 it is PTPSCBM2 and hence the warning. Could, perhaps, be the reason Nox'es need reset after updates... Thanks!
  15. I gave v3 another try today. The Nox was stable, but unfortunately first impressions are not great - this is probably the first time I come back empty handed, and that place always gave something. I even tried digging all iffy signals. The contrast with 1.7.5 is that Nox was unusually quiet over mineralization, very little negative grunt, and I know it is there. Bit better with EMI. I think it falses more around iron. And it made me to dig 2 cast iron pieces, that were giving solid 20-21, this I did not like at all. It used to be 13. On those grounds 20-21 would usually be a coin under the coil. Something to think about.
  16. So after few days of struggling with the Nox even after rolling the software back, being overly sensitive, unstable, picking unusually a lot of EMI, finally narrowed it down to coil itself. Looks like it picked something odd inside the coil cover and after cleaning it everything returned to normal. I don't think I ever cleaned it or thought it can have any effect. Lesson learned.
  17. Chase, thanks very much for a detailed answer and time to reply. In regards to settings, I only wanted to say, that after having a lot of hours with the machine, any deviation from usual behaviour is noticeable, to me. I generally prefer to run the machine hot and don't mind a good bit of sparkiness, but this time it was noticeably much more of it that got my mind tired rather quick. By it I mean how Nox reacts when swinging over edges of rusty ferrous stuff, when IDs jump all over the range, but rather without any repeatability or pattern. Firmware wise, I went up and down countless times, spending a good bit of time in each. When I mentioned F2, you are right, it was my experience using v2 before going to earlier versions. Curiosity wins and I start juggling firmwares again, but tend to return to familiar 1.7.5. Thanks again
  18. Have to say I forgot to reset prior the update, but did it few times after. Updated from 1.7.5. Rolled back and will go there again.
  19. Of course. But I wasn't comparing different things, I always run in same modes and behaviour in my experience has changed. I usually detect in Park 2 or Field 1/2, multi, speed 3-4. I rarely use Noise Cancel as it is never an issue (I mean, I even run external gain amp without EMI issue), but had to try it few times, it didn't help to reduce EMI even with stock sensitivity 20. Field 1 was always very different to 2 - 1 being a good bit more cleaner/quieter, while Field 2 quite revealing and sparky, especially on rust. However, yesterday they performed pretty much identically - both sparky jumpy sharp. I don't use FE or F2 rejection (always 0, somehow I have no problem with iron), however F2 yesterday seemed unusable (way too sparky on every ferrous object and there is a lot of it there), while FE was more or less usual behaviour. The field with very porous soil (rain worms heaven) that I went to always used to GB to about 1, but it has a lot of coke in it, yesterday it balanced to 68!? Ah yes, the coil bump was very apparent too! In my area, 5KHz always picks up lots of EMI, however 4KHz were quiet, nice. I only gave it a short run, the Nox was reacting to coke a lot in 4KHz, so I switched back to multi. I wonder if it didn't update correctly, I didn't expect to get such a different detector.
  20. Just tried V3 myself for the first time. Not sure what to think of it. Did they make it more sensitive? Anyone got worse results in regards to EMI with it? I couldn't make it shut up all evening, it was chatting pretty much all the time, less so with coil closer to the ground, and very sparky on rust. I usually run it on 24 to max sensitivity no problem, but yesterday 19 was the highest I could go in the same area I checked dozen of times. At the same time, I picked few small shallow things, that I somehow skipped over and over, as they were right on the path I always take and check. Can't quite understand if I like it or not. Definitely different to V2!
  21. I find most countries have similar laws, strict laws in fact, in regards to detecting. Where I live, "good" detectorists and, generally, ones respecting the heritage, try to stay away from such sites. Fortunately, we have online maps that highlight such areas. Good way here is to check the map, ask for permission if possible, then go. Different countries have various descriptions of term "archaeological item", which can be vague at best, but generally excavating "archaeological" items is forbidden. Musket balls are few centuries old and may qualify as archaeological items, and if found in large quantities, the place may carry significant historical value. Excavating in such places, simply put, distorts and, even, wipes clues and the picture of the past of that place. So... it is not surprising archaeologists are not fond of detectorists 🙂 Hiding it makes even worse. It actually takes the joy detecting away. Do some research of the place, ask permission if possible, and enjoy detecting. Have a look through comments in this link. It gives clues about the law in various countries. https://md-hunter.com/list-of-countries-where-metal-detecting-is-allowedbanned/
  22. Just to add, worth checking detecting laws, archaeological zones in Sweden. If you find a lot of musket balls, the site could be of an archaeological/historical interest and one can get into trouble detecting there. Some countries are stricter than others.
  23. I was long advocating the 1.5, but have to admit 1.7.5 is probably the one I would always go back to. Didn't have a chance to test the v3 yet, but it sounds like it is more or less similar to v2. I liked the upper versions due to their ability to handle EMI better, especially after adding artificial gain circuit.
  24. They feel different, but as others say, hard to tell how exactly. On my floors full of nails, Park modes seem to see coins, but Field modes do not, just a bare squeak. However, Field modes while outside, at least here, seem to be able to pick faint signals from depth better, at a cost of being a little chattier.
  25. I thought it will never happen to me, but 1 ear on mine has broken. Glued it back and it holds it seems. I think the problem is rather with the rubber shims that are inconsistently grippy in dry wet or dust, putting too much strain on the hinge. Have put thin plastic shims to reduce the friction and so far it seems ok and easy to flatten the coil against the ground if needed. Fingers crossed.
