When to stop (how deep)

[grego]

A very interesting post, Now i will have to go out and try to find those signals again.

There is one thing to remember with things buried deep and that's the owner of the land.  Personal experience has shown some Farmers to be like Hobbits.  I have 2 old cars buried in my field by one previous owner and I know the Farmer at the back of us buries his old rubbish,  just takes his digger, digs a big pit and I mean big, then disposes of old machinery he can't use or sell.
Makes you wonder how long they've been doing it.

When we dig deeper than the plough soil we are disturbing on the whole natural layers of the ground. You can argue that sub soiling machines go deeper.
They dont go that much deeper as far as i am aware.

Look up subsoiling they go deep, its one of the deepest tools, along with the mole plough, the normal plough just skims the surface, compared to them........have you ever detected ploughed land dry on top with all the water sat on the sub soil? that's what its designed to stop, so it needs to go deeper than plough soil.

when I detect a field what the subsoiler has been through I worry about what items that has fell down the deep rips never to be seen again

Wrong way around Dale, subsoiling increases moisture retention at depth

yeah by opening the ground to allow the water to drain away, did I go wrong in my last post somewhere? It may be years of missing school

We did a rally in Hereford winter 2012 I think it was, and the furrows the farmer had ploughed in the potatoe field were over knee deep

i had similar tale ,it went on for weeks ,with 2 machines to check it out ,but the crater got deeper and wider .
in the end i put it down to minerals in the ground and no large object was there .
i must have dug the hole in and out for 15 times to no avail.
i used to dream about it ,it got so bad .

I kept getting a diggable signal on Barry beach the other day. Kept going down and down even checked with my pinpointer but couldnt find the damn thing. Eventually I stopped scanning and dug like hell wider than than the coil diameter. Eventually found a tent pin that had kept slipping down through the sand as I was digging it.

Ive also had a strong diggable signal on a roman villa site which turned out to be a 6 inch wide lump of melted lead about 24 inches down.

Or the multiple plow shears we all had on a DW rally in Boverton where the stoney subsoil was just ruining plows and leaving huge chunks of iron behind.
