has anyone done anything like this? I was thinking about getting my snorkel set and a screen bucket and start sifting out the ocean floor at around 4 to 5 feet deep where everyone swims? Think this will work??
I think it depends on your definition of "work". Are you talking about randomly picking a spot and not using a detector? If so... you're definitely in for a lot of work. You can get the same results as picking a random spot on the beach and start sifting... you'll stay drier and the work is a little easier. Of course, you can increase your chances of good finds by picking good spots: end of piers, underneath floating docks, small swimming holes.
Your best bet is to get a water machine. It is a lot less work, a lot more productive, and more fun too

Back in the days before underwater metal detectors existed. I wrapped my Garrett ADS machine in plastic and floated it on a sifting box and with a long 9 foot coil cord and 8 inch head, I was able to hunt in water 5 - 6 feet deep. There used to be a booklet out that Kellyco carried on how to build a pull sifter. I had one built and pulling it is a chore as I altered the design from 12 inches wide to 18 inches. It costs $100 to have it built in 1979. Its real handy for sifting a trashy swimming hole full of pull tabs and other metal junk before switching over to my Excalibur. Its real handy around fishing piers that are nortoriously trashy with hooks, sinkers and lures. Always find clad change and jewelry mixed in with the garbage.
I plan to use it again at Daytona Beach when the water warms up again. I've never been able to battle the incoming waves while detecting. Alway get knocked off my feet by a big roller. So I'm going to try my old sifter once more and see what I can sift up.
I'll post a photo one day when I'm at Daytona with the sifter. I'm thinking of having one made out of stainless steel so it doesn't rust and drop it back to 12 inches wide.
used to do this as a kid under the seaside board walk in like 1970s only found change quarters dimes nickels under the stands, rides in the sand not the water.
