I normally don't park hunt, I detect a lot of older homesites and on occasion a tot lot near my house. For bigger parks and such should I not have to worry about the Vaquero missing gold jewelry, especially rings? I have both the stock and 5.75 concentric so i will use both. Does depth of a ring make a difference on how the Vaquero will pick it up compared to detectors that are more dedicated to park hunting. I'm just curious as to that and if I should limit sensitivity or if that doesn't matter any tips are appreciated.
