Just lots of gridding Wally, maybe digging a few more different types of signals, haven't really changed my approach, just lot's of people about this year. I think I've been spending way more time at beaches than parks too and it's paying off, I've never done so much beach detecting.
Cheers Art, I think these precious metals can be any TID depending on alloy, I got a 23k gold ring once that was more like a sterling silver signal at 12:44-46. I thought this ring was silver at first until I saw the fineness mark. Then I thought platinum but it's not heavy enough for platinum, SG test puts it right near 850 palladium.
I know there are quite a few different alloys they use with palladium and platinum.
