This time I worked with my settings practicing metal discrimination. Avoided all the junk and spent a lot of time on coin-finding instead. Almost got silver. That quarter is just one year off when the silver quarters stopped. The filtering worked pretty good but a dasterdly rogue piece of scrap rebar had me going for 30 minutes on one dig. Kept all my fingers. Good to go next week while I'm in Hawaii and sand-detecting next.
