Hi, I'm Peter Welch
and I use Google Earth
to find where ancient artifacts are buried.
Most people, when they start detecting,
you find a nail.
You find a beer can.
Average stuff.
And then you find your first coin
and that's where the interest
starts to grab you.
I thought, "There's something in this,
organizing digs for people."
So I formed the Weekend Wanderers.
We quickly grew to be
the largest metal detecting club in the country.
It's not just about finding things.
It's research, conservation
and studying history.
When you're on the ground
you cannot see
where people from prehistory lived.
So with Google Earth
you can trace a crop mark
because it shows you
signs of ancient occupation
like buildings, roads.
That's where the interesting stuff lies.
Our most significant treasure find
was in 2014 on our Christmas dig.
One of the guys came back
and said, "Oh, I've got a hoard of coins."
So I looked down the hole
and there were two or three
stacked coins.
And I said, "Oh my God,
it's Anglo-Saxon."
I had to go and tell the farm owner.
He was busy with the sheep.
And he said, "Oh, yeah, whatever."
"We need to sort this out."
And he stood there with his mouth wide open
couldn't believe what he was seeing.
It's a million pound hoard
on his table.
Ultimately it goes on display in the museum.
There's a lot more land to search.
One day we might strike it big again
and I'm pretty sure it won't be long.
To all those unearthing history
Search on.
