Just came back from a site that was about 100 years old with a stone house. I found a hand full of clad but here's the "rub"......most of the clad was at about 6" and the dirt was almost like sand. Very soft and a lot of roots. My question is .....Do coins have a tendency to sink in soft dirt ? If true then there is a good possibility that silver is deeper than I can detect. Any ideas ? Is this a location for a bigger coil ? I've seen this before and now I'd thought I'd ask the people with more experience .

Not an expert, but gravity does work underground as well above ground. Here where I live most of the coins aren't that deep. The only reason I can think of that might cause this is the huge rocks and roots that are common in my area. Remember: when you step on soft dirt your feet sort of sink. When you step on hard packed dirt your feet don't sink. Same thing happens with coins, it just takes longer for then to sink.
I was thinking along the same idea. I guess I'm going to spring for another coil. I'm going back tomorrow and go over the area again. I was getting a lot of "hit and miss signals" which suggest trash but it also may be deep targets. Given the soil type, I'll try again. It started to rain (again) so I pack up and went home.

You should do the "twitch" over those iffy signals and some will turn to good ones.

What's a "twitch" ? I tried sweeping the coil in several directions, unable to lock a "repeatable" target. I even tried "stamping" the area with my foot to get a lock, thinking of that "halo effect"......... even though that has to do with size, I thought it might work in this scenario.
There are a lot of theories on how coins get to the depths they are. Personally, I doubt if they sink at all. Fill up a jar with dirt or sand, place a coin on top and watch it for a couple of years. Did the coin sink at all? No it didn't. In the woods, coins get covered with leaves, which turn into the humus layer. It can be thick. However, I have also dug 80 yr. old coins in the woods at 1/2". Finding coins at houses is a phenomonum on it's own. All that watering and fertilizer on the grass, plus worms coming out at night spreading dirt + gue on top tends to get them buried a little quicker. And then there is the old settling of the house. What does a home owner do to compensate for this? Well, he spreads more topsoil on top of the low lying areas. And,a quick cure for a bad lawn is to add 6" of topsoil on your lawn and seed it. It's no wonder that coins sometimes are found at incredible depths around houses.
Well, that's been my experience. And I too have added lots of topsoil on my lawn too.

You said you left when it started to rain...............that's ok, BUT:
If you go back and detect after the rain ends, you'll find you're getting maybe one or two extra inches in depth
due to the wetness of the ground. Also, usually easier digging in most soils when wet.
I still only have the standard coil but am saving for both sniper and 6x12.
On Social Security and with the price of medications, can't go and buy like I used to do!

If so I'd try that and only dig the short repeatable signals. Also I think freezing ground has some effect on coins depth too? I love the deep soft signals!
The GTI 1500 doesn't have a true all metal mode. It has a zero discrimination mode, which has had some of the real low and high conductors removed, so you don't hear EVERY signal. It automatically boosts the weak signals so you can hear them. It doesn't have a modulated audio system where the deeper signals have a weaker signal. That's why they have a depth indicator on the screen. Many years back, people were asking for a detector that could give you a depth reading and automatically boost the weak audio signals so one could hear them. So Garrett incorporated that feature into the GTA, GTI, & GTP models. This also allows you to hunt in silent search and not miss those "weak" signals with the threshold set very low.

No true all metal and has faint target audio boost.

Ain't that the truth and it ain't going to get any better - although under Bama's stimulus plan you'll get a free check in May for $250. There's your coil money.

Yeah I've dug coins from the 1700's at two inches and clad at 6-7 inches in the same area. Go figure. No out smarting old Mother Nature.

There's countless post on this forum about it but here goes again. Just center your coil over the target and whip it rapidly side to side about two inches each way. This will turn many bad signals into good ones. This is the nature of motion detectors. The faster they move the deeper they go and the better they discriminate.
