0:00If we look at um a lighting column. So this is a plan view looking from above and imagine looking down um and we've got our lighting column here. If we get our Jenny and we hook up and we put it quite far away, let's say two or three meters away. So this is the earth wire. Now I'm I'm pretty sure that you would all agree, wouldn't you, that this earth wire is giving off a massive signal. Yeah. Agree with that? So in other words, what what effect what this means in the real world is that I can't go here with my locator. If I go in that
0:31area with my locator, I'm going to pick up the earth wire, not the cable. If the lighting cable happens to be in that area, I'm not going to be able to pick it up properly. So what this means in turn is I have to move further away from the column. So instead of doing that, consider this. That's our lighting column. We get the Jenny, we hook up, and we put the Earth really close. Everything's tight to the column now. Everything's really, really close. And I can now do a nice tight circle around that with my locator. And it doesn't
1:01matter which way that cables goes, I can still locate it. People often ask me, "How close to a column can you work to, guys?" It it's more about where's your Earth? Yeah. Have you got that stretched out miles away? And it's and it's interfering with what you're doing. So So put it nice and close on a column. Okay, that makes sense guys. Happy with that? There are reasons for moving it further away and we will cover them later guys, but for now just consider that. And the
1:31also thing I want to touch on guys is we're still using like old habits from years ago. The anyone remembers the old handbag jenny's the old the older Jenny's. You did have to move it right out at 90 degrees to get a signal. But you don't these modern jennies are fantastic. Jenny 4 is a cracking jenny. Okay, you don't need to do it with these now. you'll get buckets of signal uh down that lighting cable just by putting it close like that. Okay? You don't have to go far away and then you can work really tight in then as well with that with that lighting column. Okay? So
2:02hopefully you're okay with that. The other thing that I want to start discussing with you now and we do go off on tangents
