Beach conditions are going to determine most settings. On my beaches here in SoCal, I like Park 1 for dry sand and Beach 2 for wet and water. Sensitivity as high as you can and still be stable. Target volume all the way up. Low threshold hum (whatever is comfortable for you), iron on with a low tone, 50 tones, recovery speed dependent on target concentration, and whether you're in the water or dry sand. Sometimes raising the recovery speed will get rid of water falsing. Around fire rings and tables, I use 8. regular dry sand with few targets, I use 3. The more targets, the higher I set the recovery speed unless I'm in an area where going deep is a priority. In the water, it just depends on how chatty it is that day. Salinity and rougher surf can change that setting. You get into black (magnetite) sand, volcanic sand, brackish water, and you may have to play with some other settings. As for ignoring iron, just ignore it. It all sounds the same tone. I'd rather know it's there and may be affecting a non-ferrous signal than to pass up a sketchy good target as junk when it's just the iron next to it causing that. If 50 tones is too much for your untrained ears, go with 5 tones, or even two if you have to. I just like the nuances of 50 tones land hunting, and just never change it when in the water. Doesn't bother me a bit at this point. If everything sounds the same, I go "ear blind" after a while. I like all the different tones to keep me on my game. Oh, and I scoop every non-ferrous signal at the beach. I've had some amazing finds that read 2. You'll dig sh*t loads of gum wrappers and tiny foil in the dry sand, but, just one gold/platinum diamond ring will make you a believer. In the water, you usually don't have that problem with tiny foil.
