Now copper I could see...
I have deep crab pot pieces give me a null, then a scoop I get broken tone.. another scoop or two then back to a solid null. But had gold rings do the same.. except that third scoop I get a nice (non-broken) tone.

Good insight from youz guys, thanks

I dig all broken tones many times they turn out to be gold or little pieces of a gold ring... when I get a null if I get a small squeak of something I will investigate... I don't want to leave any good targets for the next guy...
possible compact/tight formation of rust that sounds off at first, but when you scoop it, it breaks up and is no longer concentrated enough for the detector to detect. Or a small object that was the right angle/surface area for the machine to get a read on at first, but then the angle changed after you scooped and the machine doesnt have enough surface area to detect it. On land, I've had a signal disappear - only to eventually find out it was stuck to my shovel!
I have had that dirt digging as well when I found a cut hammered silver stuck to my shovel

We could start a whole new thread on treasure stuck on our shovel tips. It's part of my routine to look at my Sampson shovel once the hole quits and the dug pile doesn't get a hit. In my case, it's usually a ring tab of a can, or I speared dead into middle of part of a aluminum shard.
Some signals just vanish to the metal detector, and I figure it's a broken halo. Are there halos hunting beach sand?
I first thought it was a piece of foil until I rubbed
I didn't have any water with me... what is one more scratch anyway lol... https://metaldetectingforum.com/album.php?albumid=5329&pictureid=83200

This...you are taking away the conductive sand above the target. All the above is true as well target sinking...fresh salt water flows over target reduces conductivity...target changes orientation etc... happens a lot with my nox

I started this thread and was out on the beach today and the same thing happened. Signal was strong with a high number.
After a scoop or two the signal completely disappeared. More scoops and still no signal.
This time i had a pinpointer and it started chirping in the hole. Turns out it was a skinny wire tent stake.
Initial digging must have changed its orientation enough so the detector could not find it again.

That's why I carry my pinpointer at the beach. I can go through a pile quicker with it than I can trying to sift it and small objects are easier to find.

It sounds like you are trying to be too precise on your target and the initial hole you dig. Expand it by 1st , taking a scoop out on each side of the target. A slightly bigger hole for the entire coil to fit in will help. Until you have it mastered ( if this happens often to you). And I never use a pinpointer !
I use them in my sifter our pebbles are the same color and size as bits of lead or 22 cal bullets.

The sand in this area doesn't flow through the holes in the scoop very well. It just clumps up when you dump it out. A pointer definitely helps locating small bits.

You can't knock it down and spread it with your foot ? Is it clay or something...hmmm

It can be spread but unless you make it paper thin small objects are hard to see. It is just quicker to pull out the pointer and drag it through. It's just sand but not like that sugar sand that just shakes through the holes especially if it's damp. It's more of a coarse grit. I don't know how better to describe it but a coin will have a full coating unless you dip it in water. Of course in the water it's no problem.
