Both of my parents used the old coinmaster and I don't think they left many nickels. They would come back with a pouch full of pull tabs and bottle tops every time. They dug everything. My aunt did the same thing. Maybe there wasn't that much discrimination going on?

Just use the "tap" method to get all your gold(and shot) to one side of the pan then roll the shot out with your finger. I do it all the time.

Can't get your pic to open Steve

Nice finds... (couldn't have been much of a lawn with that hole!)

You might check and see if your connection, coil to machine is tight. Sometimes that will cause goofy problems. I've found mine will work loose occasionally. You do have an adjustment on your threshold...... should be able to adjust it until sounds good.

I was detecting at Pismo one day and I hear this giggling above me...... looked up to see a couple teens throwing pennies ahead of me.

Anyone who has Ray's book knows it has a chapter on the GB Pro....

They found the ship, not the gold as your heading to the thread says. Maybe it will be there.... make a good story.....

What will you be swinging?

Since you are new to detecting and are heading to a park, you might ask here about some advice on digging signals in public parks. I know you'll get some.

Yep, most likely at the mint.

Only way that could happen would be if another dime was pressed into that dime.... another dime left in your hole?

let's see the other side.....

Nice........

More than I ever want to know....

Some people want it handed to them on a platter.... grin

They vary depending what a person wants to use. Short ribs, tall ribs, miners moss and screen or a combination as shown above...

My misunderstanding..... I thought that being so small (3.5"), you were classifying your concentrates. "This will take trowels full of dirt, and separate black sand and gold from the rest of the larger and lighter materials." This is assuming that someone installs the correct recovery system. My thought is that you should design the recovery system(s) also. Seems incomplete without it. "Classifying only takes a few seconds, so it's not really a burden". That would be assuming that you have a classifier(and sprayer if material is wet) attached to the sluice to spoon feed one scoop at a time. Classifying is time consuming and a burden. I've classified many cubic yards of material to "scoop feed" a Gold Cube.

My thought that 1/4" thick plastic is heavier and, maybe more expensive than aluminum? Have you compared weight and cost? Aluminum is a lot thinner. Once you have classified your material, you can pan it down in just a few minutes. A pan is a lot lighter than a recirculating sluice.... You still have to pan it after it goes through your setup. Have you considered that? Sorry if my comments seem towards the negative side. But, you need to think about all aspects.

Not really a folding sluice.... more like a "recirculating sluice" setup with two sluices. 3 1/2" wide is really tiny. Why so small? Since there will be no recovery riffle/mats/screens, how do you propose a person hold their recovery setup to the bottom of the box? Keep at it........get it right.

There a bunch of threads on coils down in the "Garrett metal detectors" section (where your question will probably be moved to) Too many to list.

Sounds like a great place to detect.... but, there are probably a ton of active claims there??

Nice buy for $8 Not sure why they put a "D" handle on a long handle though........ No leverage.

They have been for years, haven't they?
