Hey guys.
Hope you're well.
I hope you're all having a great day.
For those of you that don't follow me on YouTube, Instagram, Facebook, LinkedIn,
let me introduce myself.
My name's Ben.
I run a company called Geelong Cable Locations.
And I just wanted to show you this job I'm on at the moment.
We're out on site.
We've been doing all the locating down that way
and all up this way and we're doing the potholing.
Digging down and exposing where the underground services are.
And I got the opportunity to show you a system of locating
and I thought this is a great chance now that I've got the services exposed.
So, if you see down the bottom.
Down there.
That pipe right there.
The grey one.
It looks sort of grey in color.
That is a gas main.
So there is a gas main that we've been locating
and potholing the whole way down there. And as I say, the whole way up there.
Now, when it comes to locating, the best way to locate something
is to hook onto it using your induction clamp,
or, better still, bite onto it using your alligator clips.
So you bite onto one end with that,
you use... put the other end into the ground, into the soil, and set up on earth
and that's how you trace it.
That's the best way to locate something.
Ideally.
This gas main, unfortunately, we couldn't, before we exposed it
we couldn't hook onto it anywhere.
There was nowhere to hook onto it.
So, all we did is called Induction Method or Spillage Mode.
In America they call it Induction.
In Australia we call it Spillage.
Means the same thing.
Basically, what you do is you grab your transmitter,
put it down on top of where you think the gas main is.
Generally you get an offset from the house or from the property line.
So, we've got an offset from the fence, or where the fence should be.
Put the transmitter down and then you walk along with your locator and mark it.
The issue generally with this method is that you don't get a good depth.
But, I challenge that theory.
I say it myself to a lot of customers that when I give depth
without hooking onto it, it's only a guide.
I would like to hook onto stuff.
You could have issues.
Out here it's been brilliant.
Now, before we start,
let me just explain:
Guys, I don't do training.
I don't offer training.
We don't sell training.
We don't do courses.
We don't offer any of these services.
Often I'll do videos like this and people will say:
"How can I learn from you?" or "What are you selling?" or any of this.
I'm not selling anything.
I just want to show you an example of how it works
and how you go through it.
But let me just clarify: I'm not selling anything.
But, if you are a locator, if you want to do this professionally
or even if you want to do it for your own business
I highly recommend you get professional training.
There are a lot of companies out there now,
a lot of courses that offer good courses on how to locate.
You still need experience.
You still need to go out and do it properly.
But, yeah,
I just want to put that caveat in there that I'm not selling anything.
I don't give any training.
Other than my own guys that I train, obviously, that I spend six months or so
training them, or probably more.
Anyway, alright, so, let me run through how to locate this gas main.
Actually, before we do that,
let's measure it.
Let's see exactly how deep this gas main really is.
Oh, where are we?
900 give or take 10mm here or there.
Let's say 900mm deep.
So let's run a little experiment and let's see how we go.
Now I'm going to cheat a little bit.
I know the gas main is here because I located it before.
But let's put it back on top.
Turn on.
What frequency are we going to go on?
Yeah, let's have it at 83. 50%. That's fine.
83.
Good.
Alright, so we know it's 900mm deep.
What does the locator tell us?
Locator tells us it's 5.8.
What's that, 5.9?
It's bouncing a bit.
What's happening is...
Let's turn this off for a sec.
Look at the distance we are from the receiver to the transmitter.
We are too close.
We're transmitting via the air to the receiver.
We're not actually transmitting onto the ground onto the pipe.
So, it still does make you think you're locating it,
because you're going like that.
But all we're doing is getting a signal straight from there.
Straight over to it.
Rather than onto the pipe itself.
Let's leave that there where it is for the moment.
Let's go for a walk up this way.
And there we go.
Have a look at that.
1 metre.
That is more like it.
So, I reckon it's probably a touch shallower than that.
Oh, there we go.
Now at 900.
Again, the ground conditions could change.
There might be up a 100mm or so up here.
But look how far we are from the transmitter.
Now you may say that it might have been deeper in this section here.
So, let's do the same experiment again and go the other way, where we've
already exposed it.
I could go up that way, but it's a bit further to walk.
Right there.
1.1 metres deep.
Now, let's... Same experiment again.
Alright.
So we're straight on top of it.
Now, let's see what depth it tells us at the actual pothole itself.
And there we go.
Spot on.
So you notice the only difference is...
We're still at the same spot.
The only difference is we've moved the transmitter further back.
So it's a mistake a lot of people make
is that they'll transmit the signal through the air.
Airborne.
Rather than down in the ground.
And it's a simple thing of just moving your transmitter further away.
Alright, let's just try again.
All we've done is just moved down further down to another hole.
Should be exactly the same, but I'll show you.
So, look how close we are.
Let's turn this guy back on.
Now you see the pipe in there
is about the same depth.
I actually know it's 900 because I measured it before.
Actually, have a look.
Have a look over here.
When we located it last time we even said 0.9 deep.
Anyway, let's get back to
what the locator tells us over here.
And here we go, the locator's smart enough to realize we are too close.
So the locator, yeah, see how it's smart enough to realise that.
Let's go back a bit.
Let's... Actually, what have we got here?
There we go, 0.9 deep.
That's from last week or I think it was two weeks ago now.
That's why the paint marks are starting to go.
Let's see what the locator tells us.
There we go.
The locator is telling us it is 5.4 meters deep.
And why?
Because we are too close.
So again, if I moved the transmitter back over there to there again
or I moved it back over there to the other spot
I'd be able to get the depth at 900 which is what I did originally.
So all I want to do is just show you that
you can get good depths just by spillage mode
or just by induction mode.
Simply by putting transmitters down.
But there are some skills to it.
Or not skills,
there are some techniques to it that you just got to be aware of
and the common example is this.
That you've got to be a fair distance away from it.
You can't be too close to it.
Alright, guys,
so that's it.
I just wanted to quickly show you while we've got the pipe exposed
and while it's pretty quiet out here.
It was windy before, it's actually not that bad now.
So it's a good opportunity to show you, just an experiment to show that
spillage mode does work.
But techniques you've got to use and systems you've got to
put in place to make sure you're doing it the right way.
Hope you've enjoyed this video.
So for those of you that don't follow me...
Look, we're on Instagram Stories
we do every single day.
We do a few posts on Instagram as well.
We're on Facebook.
We're on YouTube.
We're on LinkedIn.
No doubt you're following me on one of these channels at the moment.
You're watching this at one of these channels at the moment.
So, hope you've enjoyed this video.
If you like this sort of stuff, feel free to subscribe
and follow me for this stuff a bit more,
bit more often.
As I say, I don't teach these sort of things.
I only want to show...
The idea of me showing you this is so that you realize,
for that those of you that do locating, realize techniques you've got to do yourself
so you get better results.
And for those of you that don't do locating, so you understand that this
is why you hire a professional because this is the results you get.
You want to hire someone that understands why the locator is doing what it is doing
and how to avoid it and how to get good results out of it.
Hope that makes sense.
Anyway...
Guys, you take care.
And we'll talk soon.
Bye.
