  1. That intro video is hilarious. Like comically overblown hype with similarly comically bad CGI. Lol! Guess the coin and relic crowd is a bit different than the gold crowd.
  2. Maybe a tiny amount of material would leach out but only the outermost molecules in the nugget would be exposed to the environment. I'm more referring to the depositional environment - the bedrock or clay or whatever acts just like a sluice to catch gold particles. It also catches heavy materials like iron-rich minerals. Those other materials are concentrated along with the gold contribute to the response. When you dig, you disperse all the other stuff and the response is no longer the both gold + nearby concentrated minerals, it's mostly just the gold, hence a lesser response.
  3. Nugget halo makes sense to me. You'd expect iron-containing heavy minerals (ground noise) to settle in along with nuggets. It's not that the gold itself is interacting with its environment, but that the process that guides nuggets to their resting place also accumulates materials that give a bit of a signal. When digging, you break up the previously concentrated and defined volumes of metalliferous material which surrounded the gold. I'd be confused if a nugget in its "original" spot *didn't* sound different than the same nugget buried at the same depth, with same orientation, in the same now-disturbed ground.
  4. That soft, low-pitched whomp is just screaming "dig me"!
  5. Talk about Real Hard Yakka™️ country! I suppose prospecting style picks will do pretty well on ice.
  6. A major lesson learned after moving to Australia is that friends here use words that, in the states, you don’t even use for enemies (much less suitable for this forum). JP’s post was actually quite warm and fluffy relative to the usual vernacular.
  7. Gerry, Might wanna slow down there buddy. There are some older folks on this board that need to watch their blood pressure.
  8. Great results Simon. I expect ML will replace the 11" coil. Hopefully they take responsibility on a larger scale for the apparently quality issues with the coil and detector.
  9. I’m sure the individual employees are decent people, just the company policies which are lacking
  10. Yeah the 6000 & its headphones use aptX low-latency. Best case scenario with aptX LL is 40 ms latency. Not many devices implement this codec and few do it well, many are closer to 100ms latency than 40ms (50+ ms is unusable for realtime anything IMO). Non-LL aptX bluetooth latency is usually ~200ms, definitely unusable and laggy as hell. The 6000 headphones implement this codec properly so they aren't laggy. This is a rarity, kudos to ML for doing it right. Miners Den has clearly just made a deal on Alibaba for this product with no design input. Compare to the Quest wire-free kits. They use a totally different, lag-free wireless technology, good build quality and retail for less than this Miners Den kit. They also offer kits for 40% less that let you use your own headphones. Their devices are clearly designed by them for metal detecting, though I'm sure manufactured in Asia. Miners Den has a reputation here for poor customer service and cash grabs like what this BT setup looks to be. I don't know anybody who has had a good experience with Miners Den.
  11. Thanks JP. I have a stock 14” and month-old 17” CC x-coil, believe it is bundle wound (edit: tis spiral, thanks Simon). Out bush in reefy country with a lot of ironstone or red mudstone type bedrock I often get a fairly loud signal on the ferrite but on alluvial gravels or paddocks it’s less intense. I’ve been running auto but understand the advantage of semi auto - I’ll try that and your suggestion about elevating the ferrite today.
  12. I can "balance" the ferrite out in Difficult using the QT button but cannot balance it out in Normal. I've done the octopus (as described by @Jonathan Porter ) manoeuvre for 1 to 2 minutes over the ferrite, still hear it. Especially if the ground is hot. Am I doing it wrong?
  13. This is the big shift with machine learning (what we are, for convenience, referring to as "AI"). Computers are no longer only as good as the programmer. Computers are better than the programmer - much, much better. Perhaps disturbingly, the programmer has no functional access to the logical process an AI uses to make a given decision. It is too complex and abstract, humans generally cannot understand it, despite being able to analyse that decision-making process. Put a coil on an AI and you could have a detector that rivals and even surpasses the work of human genius. Just one example of machine learning revolutionising a data analysis problem (which humans have spent a very significant amount of time and money on): https://www.escardio.org/The-ESC/Press-Office/Press-releases/machine-learning-overtakes-humans-in-predicting-death-or-heart-attack
