Okay so today we're going to some locating
We've got an optic fibre we need to locate
It serves the entire Bellarine Peninsula
It runs along here, along the rail trail
It serves the whole Bellarine Peninsula
everyone done that way
It's an optic fibre cable
We can tell it from the marker post
but there's no indications at all
Sometimes they have on the top
an offset on how far out it is
It's been ripped off
Some kids probably ripped it off
There's no marker post...
I know it's an optic fibre marker
because it's the white with the orange on top
We've got Dial Before You Dig plans which is good
They've told us that this is actually a transponder marker post
It's telling us that there's a transponder out here
So the optic fibre is about that thin
It's direct buried
so it's just ploughed straight into dirt
It's just thrown into dirt, no pipe, nothing protecting it
Just optic fibre
We've already tried, there's no trace wire on it
If there was a tracer wire we could've located where it goes
but what we're going to do we're going to locate the transponder
There's a transponder
that sits on top the optic fibre... sits in the trench
Actually these ones here, they're either round or long ones
Pretty sure these are the round ones
and they sit on top of the transponder...
and the transponder sits on top of the optic fibre
in the trench
and what we do
we walk along with a transponder locator
and locate where the transponder is
It's good because it tells us where it is
Right now
I've got no idea how far out it is along here
so at least the transponder will tell us exactly where it is
but it's only going to tell us for this one spot
It won't down there, and it won't tell us over there
There are marker posts every 15m or so
So we can...
That one there is probably about 100m... anyway
So we can at least get a rough alignment
of the transponders... of the optic fibre
of the transponders
which tells us the alignment of the transponders
So come have a look and I'll show you how it works
Okay we've just found the transponder here
Now transponders are only laid wherever the marker posts are
Well where the marker tracer posts are
So now we're going to head down 100m up the road
I don't know if you can see Dave
Can you see him walking up there?
We're going to head down and find the next one
Let's go
Okay so Dave's found
found it down there as I showed you a minute ago
Another marker post
I don't know if you can hear it
Can you hear it?
Dave's finding it again
He's just found it
So
transponders are great because at least we know where the optic is
They're not as good as trace wires because
we don't know where the optic is between here and there
but if it's the same offset here and the same as there
then we can assume it goes straight most of the way
You would still have to pothole it, if you're working near it
but at least it gives us a guide of where it is
If the transponder wasn't there
and we didn't have any marker posts...
like that marker post there doesn't have any signs on it
there's no labels or anything on it
So if we didn't know the transponder was right there
we would literally be doing a trench
the whole way along there
trying to find this cable
which you'd be there for
6 hours, 5 hours
trying to find it
whereas right now
he's nearly found it, he's going there
Now we know exactly where it is
where the transponder is
and the transponder should be in the same trench as the cable
Okay so let me show you what a transponder locator actually is
It's raining so I've got underneath some shelter at the moment
So it's pretty basic really
That's the bottom of it
It's a Rycom that we're using
Bought this from Access Detection
Anthony Johnstone in case you need one
Get in touch with Anthony, he's a great guy
But that's it
You literally just
walk along like that
down as low as you can
walk over the transponder
As soon as you find it
it comes up on the reading
and you hear it
and that's it and that's how it works
So yeah, basic stuff
Simple, but hey it works
Anyways guys we'll keep going
and try and find the rest of these transponders
so talk to you soon, bye
