I use park 2. I figured out that in a dense trash area, turning the sensitivity down quites the nox down and allows you to pick up fresh drops more easily. The nox goes so deep running it hot, that it combines many more targets. Layer by layer, I get the goods. Besides, the competition here generally look for the easy retreivals, so I have to be quick about the fresh drops. I can always dig the deep and iffy signals. Last time I was out, I ran sensitivity at 12 and still heard targets plenty loud to probably 3-4 inches. Lots of masking goes on in dense areas(with high sensitivity)especially when there is a lot of bits of iron and such.
Less for the nox to sort out, and much easier for your ears and mind to take focus.
