Radiodetection Secondary Fault Locating

I tried using an RD8100 for the first time yesterday to find a fault. I thought I could turn it in and just figure it out. Definitely not, ended up giving up. Then I watched a few of your videos for locating and found the fault no problems today. Great videos, thanks!

Sorry, but I am a bit confused by this... it looks like you're initially using the locator on its own to locate the cable, and you note that there is a sudden increase in depth, which is where you marked on the ground with red paint (my understanding is this sudden increase in depth is where the fault is). You then switched to the A-frame and found something else further along (also marked with red paint). Then at the end of the video you came back to the original red paint marker (where the change in depth was noticed) and said that was where you need to dig. I don't understand what the second marker (made with the A-frame) was for... and why you'd even need the A-frame if the locator can detect the fault (by looking at the change in depth). Could you please explain these two points? Thank you.

Faults create a distorted magnetic field that will give escalated depth readings, which is your first indication there is a problem nearby but doesn't pinpoint the location as well as the A-frame. There were two faults on this line but the first location was worse judging by the higher decibel reading and should be investigated (daylighted) first.
