0:00is what's called a blind induction sweep. We're going to come to that shortly, Joe. Um, hang on. Have a look at the picture there, guys, or the six pictures. Uh, you'll see that the Genny's in a different position on each one of the six pictures. So, what I want you to do is just kind of keep that in your head if you like. just memorize that picture and then let's transfer it to the to the real world. If if that's my foot path again, now this could be a carriageway, guys. I keep using footpath, but it could be a carriageway. Doesn't matter. That's the bit that I'm interested in. I'm going to
0:38go 10 meters away because that's how far away my Genny has to be. And I put the Genny over the curb with a handle like that. And I scan across. Then I put the Genny here and scan. Then here and scan. If you think about the pictures before you here, scan here and scan it. It effectively does exactly the same thing as a twoman speed. But what it does do, it accounts for anything that doesn't run straight. Because as long as I scan the whole width of that on each gen position, even if a cable runs diagonally, I'm still going to find it. Just give me some feedback on that. Does
1:11that make sense? And you can see the difference between that and the two by one. 2x1's good for big areas, but footpass carriageways. I tend to think I call it a blind induction sweep. Some people call it footprint sweep or something, but that's what I I think is is a is a better way in that situation. Let's just finish off then talking about our method that we talked about. Do you remember we did seems like ages ago now? We did the lighting, we did the LV services, the L mains, the coms, we've done pipes, you know, we're locating all these things one at a time and this is
1:40kind of the last thing that we do. Um the final thing that I does the orientation of the journey to the direction of service have any effect? Yes. Um Luke, it's got to be in line with it. So the handle of the Genny has to be in line with the the utility. Roughly though, 45 degrees, you'll still be fine. Okay. Yeah. So yeah, roughly handled in line. Yeah. I think what I think I think what you're getting is if he's running diagonally under the gen, will you still get it? And yeah, you you will it's it's not bang on in line. The final thing we can do with the
