Floating Screen
The fishing thingie may be a good idea. Regular inner tubes don't last long in the sunlight.
I made one using a wood frame, about 3" high, whatever size you want. Use 1/4" hardware cloth for the bottom. Then using 3" thin wall PVC pipe make a frame to fit as snug as possible around the wood frame. Four straight lengths and four elbows. I even filed the center of the wood frame corners so that the pipe elbows could fit even tighter to the wooden frame.
Attach the pipe frame to the wooden frame with plastic wire ties. Attach a plastic container like a butter dish (with cover) in one corner for your finds. I punched four holes in the bottom and tied it to the screen bottom. Cut a slot in the cover so you can just slip your finds in without removing the cover.
The plastic foam floatie things may also work well to keep it floating. I haven't tried them but they would be much lighter to carry.
To carry it to the water I got some 1" webbing, D rings and adjustable buckle from the hardware store. I connected each end of the strap to opposite ends of the pipe frame. The strap length is adjustable. I make it very short when I am using it in the water, let it out a bit and throw it over my shoulder to carry the whole thing.
Last thing, make a tether about 2' - 3' long. Attach one end to the frame. Put a snap on the other end and attach it to your belt or belt loop. I used a rope the first time and didn't like the way it snapped when even the small waves whipped it around.
Using this I can scoop and dump. I recheck the hole and if I don't get a tone I go on the the next find. You never even have to look for your find. Very fast. The wave action will move it around enough to drop out the sand and leave your targets.
You will have to stop when the screen starts to load up with targets, junk, shells. If all of the above, take it out to the shore and pick out the things you can see. Then dump it on the sand and run your detector over it. I can guarantee you will find things in the pile of shells and stones that you could not see.
This is not good in there is very much surf. The screen will bounce around too much and if waves wash over the frame it may even wash some of your targets back out. Excellent for fresh water lakes and rivers.
