Thanks for all the replies guys.
I downloaded a Geology and Gold mineralization USGS report for Gold Basin and lost basin. I used that to pick two spots to hunt, one north of Gold Hill Mine and one south of Golden Rule Peak. Both areas had exposed quartz veins and pieces of iron stained quartz spread about. The ground phase readings on my Gold Bug Pro were in the range of 82 to 84, typical of other gold fields. I found very few trash targets once away from roads so that was a nice change. It either means there was very little trash (bullets and fragments) to begin with or it has all been cleaned out by metal detectorists. The area south of Golden Rule Peak has lots of dig holes so it looks like it has been pounded hard for many years. Not too many hot rocks in this area so I used my GB-Pro with the DP coil. The few hot rocks I did find had the typical boing sound and after digging a few, to see what they looked like, I stopped digging those. I did not find any nuggets but still recovered about a dozen bullets or associated copper/lead fragments, some very small, so it tells me that the GB-Pro was doing its usual job.
On the last day I hunted another spot closer to Senator Peak (old volcano?) and many more hot rocks there so I used the SDC 2300 there. Also no nuggets but again recovered bullets and fragments. I am 5'10" - 150 lbs and the SDC is pretty heavy compared to the GB-Pro. I might look into buying or making a Hip Stick, like I did for the ATX when I had that years ago.
Before I did any hunting I did some testing with the SDC-2300 by burying some targets in the ground at gold basin. I have BB size and #8 lead shot test targets. The SDC-2300 and the GB-Pro+DP coil saw the BB lead shot at about the same depth of 4 inches. The SDC-2300 did not detect the #8 bird shot at any depth while the GP-Pro+DP coil sees it at about 1.5 inches. I also have a small gold nugget for testing purposes. The SDC-2300 did not detect the gold nugget at any depth while the GP-Pro+DP coil sees it at about 1 inch. I dont have a scale so I dont know the weight of the test nugget. I have attached a picture of the test nugget on a dime. I read that the SDC-2300 is known for finding small gold so I it is not clear to me what the term "small gold" means. I just want to be able to determine if my SDC-2300 is just as sensitive as all the others or if it has a defect.
So the restart of my detecting adventures are still the same as previous years, with no gold found, but I want to learn more about how to find areas that have gold. I like to think that I have the right tools and methods so I need to find ground that can yield. My goal has always been to get to a level where I am able to at least find a few nuggets on each outing. I like getting out in nature and desert camping but if you swing all day and for years on end without finding any nuggets then that become a big skunk to kill. I have discussed my dilemma with other detectorists in the field and they have all told me that as long as I'm finding small bird shot then my equipment and techniques are good and it is just a matter of getting the coil over gold.
