Dear Julie,
I feel exactly the same way. As I live in Germany I don't have many opportunities to detect for nuggets. Last year in March my friend Joe and I detected several LDMA claims at Stanton,AZ. What a breathtaking area. I found lead to cast new bullets, Casings to load them up, sheet metal to put a roof on my house and wire to have it fenced in.... but no gold. Even found a burro shoe way over 100 years old. That was using my SDC2300. Both of us were using the SDC2300 and did not find gold. If you don't swing your coil over gold you're not gonna find any. Just put your time in (I will do too as I'm going back to CA in Sep2019) and the busy will be rewarded one day.....hopefully :-) Try to check spots which are not comfortable at all. Thorns, thick bushes, hard to get to places, cracks in bedrock. For a little over 2 months now I am using a Nox800. I am having big fun with it and found my hunting buddies wedding band which got lost over 1 year ago. So I found gold just not a nugget. It came in at 14 being 4.5 grams in weight. Good luck to you maybe we meet out there in CA one day.
