I have added up my zinc and clad for the past 30 days and it was really good. As stated in other post I am looking for a new detector. I couldn't help but think that the areas I have hit and the amount of digging I have done there could have possibly been more. So I did an air test with different jewlery and the results were dissappointing. Most ear rings had to almost touch the coil before sounding off. A large mens ring like I used for the first air test ran as a zinc, the ladies rings were pull tabs, scrape and foil. All needed to be very close to the coil. So my question is for the chains that don't sound at all and the ear rings are they considered as flakes or small nuggets? Should I by a detector for gold? Or is there a good detector for the small stuff? I know it takes patience and proper grounds, I have both but with the air test it just strikes up the curiosity. Thanks for your help.
