I bought a Garrett XL500 Underwater Metal Detector in the early 80s and carried it all over the world looking for treasure in my spare time. On beaches in the Pacific, especially Guam, I found lots of very old ammunition and casings.
On beaches in the Med, Carib, Socal and the East Coast of the US I found pull tabs and broken eye glasses and every once in awhile I found a cheap bracelet or necklace.
No diamonds, no Rolexes, no significant coins.
A friend who was an avid treasure hunter, as in devoted his life to it, always had 30-50 tubs full of jewelery and coins that he was cleaning.
He had a huge safe that he kept the most valuable items in until they could be turned into cash.
His name was Scotty Slaughter he was a retired Underwater Demolition Team member. I met Scotty when I was 18 and right out of UDT training. His office was like a museum and I could spend hours in there just reading the memrobelia on the walls. He had a framed National Geographic cover showing him spearing a 10 or 12 foot shark while free diving and many many articles about his treasure hunting and shark killing exploits. He had a great photo of him and his wife being crowned Mr and Mrs Nude America also. Sometime in the 60s I think.
He told me how to get started hunting treasure and finally after about 6 years of dreaming I took the first step. It didn't take long to realize that it required more than just walking or swimming along the beaches.
You have to do it for hours and more importantly you have to do it in the right places.
One thing I figured out quickly was that most popular beaches have regulars who are up early every day and treat it like a job.
Diving with the metal detector wasn't hard but you can only cover a small area during each dive.
I still try it occasionally and I still haven't made any significant find. I'm still hopeful.
