As the Colonel mentioned, each beach is going to be a little different. That's why they made these machines adjustable. As a starting point, I use Park 1 in the dry. I just seem to get better depth and stability in that mode. Usually with a 3-5 recovery rate if it's not too junky or riddled with iron, 50 tone, all metal, Iron bias on F2 @5 or higher for better bottle cap rejection, and Sensitivity as high as possible without making it unstable. 0 ground balance, and noise cancel if needed. In the wet, I almost always use Beach 2 with a faster recovery speed......5 or higher to keep the falsing down. All the other settings I keep the same starting out. Sometimes the sensitivity gets dropped down a couple of points. With your sugar sand, mineralization free Florida beaches, you may be able to turn some settings more extreme. YMMV.
