For Tim Watts - the first use of my tracer

Phone people been using these for decades, and I must confess they are wonderful when confronted with dozens of wires.

Yes, but I now have my own, no longer borrowing the works one.

Wow. Cool. I am going to look at that video a bit later after I've cooked supper.

I have a slightly less sophisticated one (just a tone generator and a amp/speaker combination) for tracing telephone cables. That looks cool though- how much/where from?

and the common phone/data ones don't work at distance / though ceilings etc, or give the same "range" feedback

Part of a dual kit

TBH My first attempt actually did not work as the emergency lighting cable that runs alongside the CO cable was live. That will limit the use in an occupied office etc.

Although I do understand the idea behind making videos for instruction of how to use things. It is quite hard nowadays for me being blind to actually find any instructions on how to do anything which is not just a yyoutube video. The simplest of devices now has a video and although often the device is perfectly capable of use by a person with little or no sight nobody ever acknowledges this fact and provides textual instructions.

They do if you use your ears. Louder the sound from the tracer the nearer the probe is to the wire. OK range isn't great my set might just do 6" but that's probably more down to the sender than the probe. Use a tone source and audio amp with a decent output voltage swing would work better. B-)

With mine the 6" is being a bit optimistic in many cases - especially if injecting a signal into a wire that is patched into a PABX or network switch. It will let you find which wire in a cable, but I would not have much faith in finding where the wire is in the wall etc.

In this particular case it was not an instructional video, just one demonstrating a device in use.

Adam was using the tracer to locate a wire above a boarded and skimmed ceiling. The tracer gave audible and visual "bar graph" style indication of how far it was from the wire.

Lifting of the ceiling tiles.

A good move in any school when you can see footprints on the worktop around the sink in the lads toilets.

It's just waiting game to find out who is going to collect what has been hidden.

One college I used to do some work for, a couple of lads lifted ceiling tiles (it was in the toilets) and snipped one of the fibre optic network cables.

They were caught ...

... but unbelievably no further action taken, I gather they were desperate to keep as many students on roll as possible for funding!

I can understand that we do similar here.
