  1. I have found several tiny nuggets in the .03 gram range with my 7000, but I am not certain of their weight. My $20 .01 gram eBay scale gives inconsistent results with these little guys. Wow, the 7000 is an amazing machine. 

    When I am working a patch and get a distinct surface signal I will often give a quick check with my GB2 to eliminate the obvious iron flakes. However, the 7000 does not like the GB2 and goes wild whenever it is near. I use a trick. When I am in a remote area without RF/EMI interference I run my 7000 start-up routine with the GB2 turned on. The 7000 picks out the 72KHz signal, cancels it  and the two machines are compatible. This allows me to use my GB2 as a discrimination tool with my 7000.

  2. The 705 with the 18.75 kHz coil is a fantastic gold machine. In Alaska last month one fellow left his GPZ home and took a 705. He found nuggets of all sizes including a 1.8 ounce solid gold nugget. At one-tenth the cost of a GPZ and less than three pounds you can swing it all day ..... and all night in Alaska. The extra $160 for true full-metal mode, automatic GB and a back light is worth it. You can not go wrong with a 705. If I were to get a fourth machine I would probably get a 705.

  3. Steve, well done, this is a comprehensive summary of Minelab's patent filings.

    Minelab's last two major patent filings 2/11/16 and 8/6/15 are bold intellectual property grabs covering all mathematical modelling methods and techniques (with any number of variables) for metal detection and discrimination.  The breath of these patents is staggering. Competitors will be boxed out of much innovation if these patents are granted. I doubt any single competitor has the resources to fight these patents although a strong case might be made they are too broad and cover an infinite number of techniques that have not yet been reduced to practice.

    Minelab anad Bruce Candy are lapping the competition on the IP front.

     

  4. Gold has responded well to the Brexit vote and the fear the whole EU could be effected. However with China's growth slowing and their demand for commodities decreasing, the world is wondering if a recession is near. Gold retreated with the other commodities last fall. Gold and Silver are now recovering. Silver was particularly hit hard with the gold/silver ration getting very wide. The big gap is beginning to close. With the British pound closing at $1.29 there are many Englishmen tonight who wish they had bought gold.

    If it was not so sad it would be humorous to watch the battle of the fiat currencies. Holders a particular currency want to see their money stay strong. However, each nation's "economic policy makers" want to see their currency devalued to make their exports more attractive and maintain full employment. We now have a Federal Reserve that has a goal of 2% annual inflation.

    Gold's future as a store of wealth is strong.
