I like Park 1 for dry sand. I seem to get a bit more depth and stability with it. Beach 2 for wet sand and water. In both modes, I run the Sensitivity up as high as I can, but, still keep it stable. This translates on my beaches to 20-22 on average. I run 50 tones, Horseshoe on so I can hear the low iron grunts, Iron Bias on F2 @ setting 6 for bottlecap identification, and I'll vary the recovery speed depending on how target rich the area is or if I need a bit more depth. In the water, you tend to need a slightly faster recovery speed to keep the chatter down. Dig everything that isn't a dead nuts iron sound. I've found some amazing jewelry that read 1 and 2, so, I'll even dig targets that dip slightly into the iron range if they also have some non-ferrous tones mixed in. You'll get fooled by some deep rusty iron from time to time.....the price you pay to the detecting gods!
