HEY MARK – Jump in here. I went from the XS to the SE and never tried the EX 2,Does this have iron mask. I run in iron mask on the beach. Manual sensitivity around 22 - 24. Go into menu and x out nails, pull tabs, screws. Check in jewelry, coins etc. I run this same setup in the old fairgrounds up here. I turn my iron mask down to about 1/4 screen. This should give you a place to start. I run digital up here but smart screen on the beach. Also with the Explorer series you have to swing a lot slower than you do with other models. They hunt deep and slow.
I'm late to the party! Been sick with vertigo and couldn't take looking at screens. Tinks set up looks a lot like what I did. Sometimes I would run open screen and iron mask. I would run sensitivity as hot as I could get away with for the site and day. It didn't take long to ignore zinc pennies if I was tired of digging deeeeep holes!
