  2. I don't see any Eastern Brown Snakes, Tiger  Snakes, Crocodiles, Wild Camels, Pack of Dingos, Hoards Files and not the last, the DROP BEAR .... There is always some good points with these Creatures they scare many non Australian Residences away from OUR GOLD.  😁

    Yes, maybe. But the weight of gold to size ratio is the give away to any body familiar with gold. Even compared to the weight of lead, gold is close to twice the weight. Gold being something like 19 grams a cubic centimeter & lead about 11 grams a cubic centimeter. Bit of a fun fact but quite mind boggling.

    Happy New Year.

    D4G

    Or over 10 ounces to a cubit inch, and that is Troy Ounces.

  4. Eric it was  like that on the gold fields when most prospector started to using the brand-new Whites and Garrett VLF (late 1970s early 80) and the holes took 10 minutes or more to dig, with a crowd of newbies watch you dig up a ground noise. ☺️ The earphones were a must in the early days even on the beach with kids wanting to dig up your treasure, A hundred of them fighting to get it first. I must admit I had one kid at a certain beach do the work and keep the non $ coins. As a matter of fact I could not get on the sand for more than 5 minutes and he would appear from nowhere. I found out a lot later that he was the only child of a single Mother so those coins were appreciated I'm sure.

  5. A good look at Aus. circumnavigate.

    I have been to all of their National Park location and done a lot more of bushwalking/hikes that they show. 

    It is a hot country so it might be a chance to forget your USA blizzard and warm you up. It is in English.

  6. The Spanish Dollar were used a lot in that era. The one I want is the 1751 minted in Mexico that the Australian NSW converted to the  1813 Holey Dollar and Dump. I would settle for any holey dollar in any condition. 🤑

    What is a holey dollar worth?
    Image result for Why was the holey dollar made
    SOLD IN 1997 FOR $37,000 & NOW VALUED AT $500,000.
    Created from a Spanish Silver Dollar that was struck at the Mexico Mint in 1757, the coin is unique. It is the only Holey Dollar created from a dollar struck during the reign of Ferdinand VI. No other privately held examples exist.

    Yup, poor guy has a faulty GPX, along with a risky helicopter, those R44 things crash like crazy.

    A guy I know runs Heli detecting tours here, ends up worthwhile too as even for NZ big gold can be found once you're off the beaten track.  He picked this one up on a Heli detecting trip around here in the mountains.  I think even an Aussie might classify that as a nugget, surely it's too big to be a flake.

    It looks like 3 penny weight next to the speck 😉

    As usual a lot of good foresight in this opening post of yours. Way back in 1979 the wife wanted to try detecting, but my choice was dredging. Anyway she got her way so we were given a Whites Coinmaster 5000 to try out at Wedderburn Vic 350 mile away. Carol was hooked so I had to go along with her detecting. The pro detectorists said the Whites or Garretts were the best for chasing gold. As the Garrett ADS Deepseeker was the newest, that what I got her. It required a lot of effort to learn and was not her cup of tea. So guess what, I inherit the Garretts and I had to get a Whites Coinmaster 6000 for her. As it was a lot easier to master I had a happy wife, and my dredging took second place to detecting. As my job was in a Power Station Control Room fiddling all the controls I took to the Garretts like a house on fire. When Minelab came on the scene I was not impressed. When ML went from VLF to PI my brother in-law got a SD2000. He had little chance of getting more gold than Carol or Me at the time as the gold size was small and he did not have the "trigger time" or knowledge of using it to it best advantage. It took 10 years for me to up grade to ML PI (brought 2 of the lastest PI then) even those I had built my own PI a few years before ML SD 2000 hit the market.

    Trigger time Hours or should I say Days, Weeks or Years spent at it.

    Location is more important than the best/newest detector. That is not flogged, appropriate to your equipment (depth and size of target) or finding virgin patches.

    Choosing Terrain which comes from experience of finding targets in many spots.

    So as usual F350Platinium you are on the ball again. Detecting is for fun, the hourly rate in dollars is usually low, so justifying a new detector has to be based on the FUN and love of TECHNOLOGY and the only thing money is good for is spending.
