It was cold! Frost on the windshield this morning. I subbed chest waders for a wet suit. Glad I did....water was cold and there was a strong south wind. The MAX is such a pleasure to use in true all metal mode. ground balance it, swing it and wait for the beeps. Low 20's are bobby pins. 40's read aluminum foil, bouncing signals 40-60-80 are bottle caps, smooth 50's in all directions gets gold, signals in the 80's to 90's get silver. Deep whispers are always a trump card. You just never know what will pop out.

Here are the rings.....I got more rings today from this old beach then I got in the previous 2 years! The extra depth on the MAX is really paying off for me. I dug up a couple of fishing lures, and made a ring out of the one with the nice designs on it. It turned out kind of FUNKY!

I was pulling old bottle caps with the cork on the back, and some had a small round aluminum disk still attached to the cork. It makes them sound like a coin.They are posted below. I included my oldest

Fantastic finds for you! Like the bottle caps. All bottle caps I've found are the twist off type. Those really cleaned up nice. Great job on the rings, too.

I guess being buried deep in the sand kind of protects those caps from the environment. I put on a thin layer of mineral oil on them, which highlighted the color a bit more. The caps faded once out of the water and dry.

but I know that rings of white read at a different i.d. point than yellow gold (similar size & shape.)
What's the numerical difference in your experience?
