  1. Hi Paul and Condor, just catching up. This is devastating. So sorry to hear about the theft and Paul, the insurance issues can be salt in the wound. I am not sure where you are now, but I live in La Quinta, CA, I am two hours from Quartzsite, AZ and two and a half hours from Yuma. If you want to borrow my GPZ please let me know, and I can meet you half way.

  2. "In the absence of the gold standard, there is no way to protect savings from confiscation through inflation. There is no safe store of value. If there were, the government would have to make its holding illegal, as was done in the case of gold. . . . The financial policy of the welfare state requires that there be no way for the owners of wealth to protect themselves. This is the shabby secret of the welfare statists' tirades against gold. Deficit spending is simply a scheme for the confiscation of wealth."

  3. Tom, you have some great pictures of your amazing nuggets. Well done! The guy who is arguably the best mineral photographer is Jeff Scovil. He has a website, http://scovilphotography.com/  ,with examples of his work and also teaches a class at the Tucson Gem and Mineral Show in February. He often uses a glass top platform. This allows him to set up lights and reflectors as well as use colored backgrounds. Here is a picture of his set up:

  4. I am not an expert in this area but in general higher ohms will give you less distortion. However it is more important to match the impedance of your source and earphones. I believe the GPZ 7000  has an out put of around 100 ohms. The standard Minelab Koss headphones also have an impedance of around 100 ohms. Given the narrow frequency output range of the GPZ 7000 I would guess that higher ohm headphones do not add much. However, individual hearing might prefer and possibly benefit from  higher ohms. 

     

    Go go with Gold Seeker's advice and compare signals with your buddy's high ohm earphones.
