Things you've found under water

[WeRtheOcean]

top ones are sand dollars

Type of sand dollar called a sea-biscuit. They are in a lot of ways intermediate between sea urchins and the regular flat sand dollars.

Yesterday, myself and my two regular buddies had a good day at our usual lake. It was cloudy with not many boats out so we were able to get to some of our favorite treasure hotspots. Our haul included: two heavy gold necklaces, one heavy silver necklace, one gold men's wedding band, six (yes 6) apple watches, a Gopro, along with the usual anchors, fishing pole, junk jewelry and bottles. The best find was my friend's clay jug in great condition. We were also flagged down to find a lost set of car keys. We were able to find them and save the guys day. Then we were flagged down to recover a ladder that had fallen off a dock. Again we we successful.
If you or anyone you know swims or dives with a Gopro or Apple watch, put your contact information on it. It's amazing how many we have found over the years. If we can, we return them
.

Great finds

I found a Flexofold sailboat propeller
That someone didn't tighten properly...
It was sticking out of the zebra mussels on a bit of a sand bar. When we where doing a drift dive...
It's even got the barcode on it. And there is zero wear on the teeth.
I don't have a sailboat so maybe someone is interested in buying it. Looks like it at least 2500$us new

If anyone is interested these are the specs on it.

16in x12p LH propeller
17spline 28mm dia.
Will fit Volvo or yanmar saildrives

What tailors aren't frustrated? A sewing machine getting suck, breaking a thread, or tangling is a regular occurrence at least for an armature like myself.

Once when I was still a Navy Diver, while diving about 2 o'clock in the morning in Long Island sound looking for some missing pieces to a Submarine which had hit bottom, in the middle of this vast flat, sandy area I found a lump of coal. It was just sitting there all by itself. I searched an area of about 150 yards by 150 yards. Just a flat sandy bottom as far as I could see and 1 lump of coal which after 20 years I still have in my own little diving museum.

Oh! You finally found my long lost Christmas present!

Some good finds from today, 3 of the corked bottles still had liquids in them. Not sure how to identify the wood pieces.

The bottom photo could be a top portion of a sliding door. Usually from a barn or a factory that might have had it on a fusible link to act as a fire barrier.
