  1. Unexpected Way To Pay For The 19" Coil

    Great result Bada Bing. Might be a good idea to go back to where you got it and start digging. The " floating gold" reminded me of what an old pro said to me once: " If you get floating flour gold in your pan, dig straight down, it could indicate a supergene" Further to this, here is an extract from one of the "Gold and Ghosts" series of books written by David De Havelland : Does anyone know more about this?

  2. Minelab Military Discount

    Minelab Australia doesn't offer this discount to Australian ex-military members (when I last asked).
  3. GPZ 7000 Display

    I purchased my Zed in mid-2015, and since then I have complained about the display being difficult to see clearly. Then yesterday I realised that it is a "sunlight-readable" display, presumably similar to what is used on some of the later Garmin GPSs. That is, when the display is in full sunlight it can be seen very clearly. I'm assuming most people here probably already know this, but I've mentioned it in case there are one or two others out there who are as smart as I am and taken nearly two years to work it out. Col
  4. Hello JW, Have you used the 19'" coil with the Pro Swing harness. Thanks. Col
  5. G'day Jen, Just been playing around with that harness at Clermont, and comparing it with a properly set up hipstick. There are pros and cons for each, but significantly JP is of the opinion that there is too much metal in it especially, with the 19" coil. I think you'll find that it is made of stainless not aluminium. Certainly with the 19' coil I had to reverse my gaiters because it was picking up the little clip on the front; also had to mount my pick further behind, because it was being detected on the LH swing; car keys in the pocket was also an issue. At the moment I'm going with the hipstick but will do more testing when we get to WA. Good luck with it, you'll love the Zed. Regards, Col
  6. Some Big Loads ! & Some More !

    These ones were in a rest area in WA. I think they are only able to travel at night because of their size. I apologise for the average quality of some of the shots
  7. This is like yarns around the campfire. Great stuff. I have one: It was October 2008 and my wife and I had been scratching around looking for gold at Maryborough, which is a lovely little old gold mining town in Victoria, Australia. We were on a trip around the county (commonly called “doing a lap”).The day before we were due to leave, I was returning to the car near Blackman’s Lead late in the afternoon after about three hours swinging. It had been a hot session and I was worn-out from digging up countless pieces of junk and only a couple of very small bits of gold. However, as I swung the coil half-heartedly when nearing the car, the signal that stopped me was clear enough but not really welcome because I “knew” it was only more junk. But you can never be sure, so I wearily commenced digging. After I’d got down about 18 inches through the hard gravel and clay I’d reached the maximum depth that my small pick could achieve without widening the hole some more, so I decided that I would return next day to finish the job. So I re-filled the hole, but before I left I sneakily put a small piece of rusty tin on top of my dig to hopefully dissuade any other prospector who might happen to wander by. However by next morning we decided we’d had enough so we packed up and headed west, leaving the undug target behind. But of course a prospector (even an amateur one) can’t forget about something like that, and countless times over the following couple of years I thought about the unfinished business in Maryborough, and questioned my hasty decision to not go back and finish the job. You might have left a valuable nugget behind? Has someone else (not as lazy as you) already retrieved your nugget, and is now driving around in a new Landcruiser? You’re an idiot, what were you thinking? You could have been rich instead of wandering around with your bum out of your strides. Anyway in late 2010 we were once again at Maryborough and I was anxious to put this issue to rest. I was much better equipped now, with a bigger pick, a Garrett Pro-Pointer and a new crowbar that I’d just bought. Locating the spot was simple enough and incredibly the decoy piece of rusty tin was still sitting imperiously on top of the old dig; more importantly the signal was still there. So I started all over again, and after digging down about another 10 inches beyond my previous effort, the Pro-Pointer was telling me that that target was just below, and some careful scraping revealed the “nugget”: A very rusty tomahawk head that some early-day prospector had left behind. So it’s now 2017 and we are soon to head west again to resume our relentless search for the elusive metal. We are still not rich, my bum is still hanging out of my strides (figuratively speaking), but at least I don’t worry anymore about “the nugget I left behind”.
  8. Poured My Own Gold Bars

    Some time back when we had some smelting and melting to do we used the GPK Company in Arizona. We couldn't find anyone in Australia at the time.This is a two person company (Patrick Moulton and Caren Seabeneck). Patrick makes a range of propane kilns from the mini up to the KK12 (12 inch diameter). Also microwave kilns.We used the KK8. We were complete novices at the time and the pre-sale and after-sale support we received from GPK was outstanding. We have no connection with this company, just very happy customers; couldn't recommend them highly enough. If you are interested check them out here: http://www.gpkcompany.com/ Col
  9. Gold Hound On Noisy Detectors

    I think the problem many of us older blokes have is that our hearing is just not good enough. I understand exactly what Goldhound and you, Steve, are saying, and as usual it makes a lot of sense. However if I run my 7000 too noisy the targets don't "jump out" at all but are mixed up in the noise and barely noticeable because the target frequencies involved are beyond my hearing range. Because of the poor response of my ears to the higher frequencies I have to rely on the target amplitude variations which is obviously less than ideal, but the reason why I keep going to High Audio Smoothing on the 7000, or winding back the Stabilizer on the 5000. What I would like is something like the BZ booster with a facility to crank up the higher frequency response in particular to compensate for this hearing loss. Some sort of mini synthesizer that could be adjusted to have a "reverse" response to that of one's hearing would be ideal, but even just a simple "treble" control would be probably help.

    Thanks Dave for putting up the link, and thanks Jase for a great video and for taking the time and effort to share your hard-won knowledge.
  11. 3.8 Ounce Gold Nugget Dig In Australia

    Thanks for sharing that flakmagnet. My hearing is so poor that I doubt that I'll ever have much of an edge on any reasonably efficient operator; just hoping not to be too generous to those that follow over where I've been. Appreciate your help. Col
  12. 3.8 Ounce Gold Nugget Dig In Australia

    Hello flakmagnet. I am wondering how repeatable were these "chirp" signals? I'm always very interested in warbles, but I can't remember a signal that I've dug that I would call a "chirp". Thanks.

    It's not as bad as it sounds; even a coastal taipan won't attack you unless you are silly enough to corner it, or try to catch or kill it at close range. Then it behaves in the manner that Gold Hound described. There was a myth that taipans would actually stalk humans, but no snake is going to waste its venom on a prey that it can't eat. Now the talk of bears, mountain lions etc., in another post here, that is scary!

    That's a great photo. It took me a while to find him. It's surprising how few snakes you meet while out detecting but I guess it's because they feel you coming and move out of the way. Not so this little fella. He stays put and wiggles the end of his tail as a lure (not for prospectors but for edible prey): In Australia I consider this Death Adder to be potentially the most dangerous of our many venomous snakes because you are more likely to accidentally step on him. He ranks about fifth worldwide on the list of poisonous land snakes, and is not very aggressive but takes offence when trod on. I didn't meet this particular one while detecting , but when I returned to the vehicle. He eventually moved out of the way, but was there each day when we returned to work what we unsurprisingly called the "Death Adder" patch. Still I like that "rattle" system; wonder if it could be retrofitted to our snakes.
  15. If that's the case Steve maybe the rechargeable AAs (1.2V) will work. I can't try it because I don't have mine yet. We use the Sanyo Eneloops successfully in just about everything else we have.
