I'm really liking this modded Cibola. You can see my settings in the picture below. I had the threshold set to a slight hum, the discrimination was set where Gatorade sports foil caps just break up, sensitivity was wide open, ground balance was set to a slight negative response. The Cibola was running quiet and smooth at those settings. I only detected for about 2 1/2 hours, because of the heat and lack of energy for some reason. I dug a few a rusty nails but that's because there were some good targets in the hole with them. A couple of them just fooled me though. I ended up finding three wheat pennies (1935, 1943, 1936), part of a silver necklace, a earring, a 1941 quarter, a 1917 mercury dime and a few clad coins. The silver necklace was about 3 inches deep and gave off a real soft but smooth audio response. I thought it might be a deep silver dime. I'm happy that the Cibola is sensitive to fine necklaces. Finding a silver dime and quarter in the same hole is a first for me. I did however find a couple of mercury dimes stuck together awhile back. Swinging a Tesoro is really fun because you just never know what you might pop out of the ground. Gold, silver or relic. It's all fun to find.
