I am having the same problem. Where I live I think it's more a matter of the ground being dug by machines and changed. I've had my 250 since Xmas and have yet to dig a silver or wheatie. Also, the places I've been searching contain a tremendous amount of trash. I suspect coins are sitting there with the trash and the detector is hitting the trash. I bet if I cleaned an area I would start to find the good stuff. I did detect a piece of rebar almost 12 inches down in my front yard, but I had the detector on max sensitivity.
Well, statistically.....the deeper you go, the less targets there are. Nearly all my coins are found in the top 6 inches, inckuding old silver ones too.

Never pass up one way signals where silver is known to exist. " Twitch" over the target and many of those one-ways will turn into keepers. Old coins with a patina or corrosion will give one-way signals. You've probably passed up more than a few keepers.

If you have a lot of trash hunt with low sensitivity and the coil an inch or so off the ground.

Well, to be honest, I consider 8 inches to be about the limit on a coin
using the stock coil. In air testing that coil, I get appx 7-8 inches,
8 inches being right on the edge.
But...Sometimes coins will show hotter due to leaching, so it's
possible to find ones slightly deeper. In that case, the coin "looks"
a bit bigger than it is.
But on the other hand, if the coin is fairly fresh, or on marginal ground,
it's possible to have trouble doing 7 inches..
But here, 7 inches is quite likely an easy mark, being our ground is
fairly good.
Most all really deep coins will tend to be sporadic, and often one way
beepers, so I agree with Uncle Willy, I bet you have passed a few by.
They can be on end, or at weird angles, and also the footprint of the
coil pattern at the deepest levels is fairy slim. So you could beep once,
and move over a couple of inches, and possible miss it on the 2nd swing.
Most deep coins will still ID pretty close. So if you get a deep one way
hit, that rings as a coin, I'd check it carefully using the twitch, and
also fast swings over the same area. If you can get any repeats,
dig it. Also, the pinpoint mode can help on these. In most cases,
if you have a true deep target, it should show up in the pinpoint
mode as long as you are not too detuned. Press the button a few
times to make sure you are getting good sensitivity. If it also shows
up in pinpoint mode, usually something is down there.
The 9x12 coil is good to 10-11 inches on good ground, and I
get about the same on air tests.
I've found coins at 5-6 inches with the little sniper coil.
In a trashy area, I'd clean all the surface junk out before declaring it a
no coin zone. Junk can mask coins.
For trashy areas, a sniper coil can really be worth it's weight in gold..
But if just the stock coil, I just start clearing all the easy shallow stuff,
junk or not, and just gradually keep getting deeper and deeper as the
place gets cleared of trash.
And yep, if you want max depth, you will need to run the machine
as hot as you can stand it. It does make a difference in the maximum
depth it can go.
This shows up quite a bit on the big 9x12 coil. I'll lose a couple of
inches if it's set back 2-3 notches. In fact, I can't get the maximum
depth of 10-11 inches unless it's almost all the way up.
Course, you can't always run like that, but if you can, do it.
I'm used to the chatter, so I can run mine pretty hot most anywhere
except the worst places. Chatter doesn't repeat. Real objects will.
After a while, you can tell which is which.
My $2.31 worth anyway... :/

I've pulled quarters at ten iinches out of damp bark chips. Just depends on the circumstances. There is no given.

That is if the mineralization is low otherwise it is self defeating.

the mulch here is frozen solid here, I was at a tot lot yesterday and could only get at the coins within the top inch. so I have to go back once everything thaws around here (Chicago).
