Can anyone advise me on such systems.
"Flexitraces" seem to be £500-1000. Are there alternatives, and what other kit do I need to use one?
Can I, for example, attach a transmitter to my drain rods and detect that a few metres away?
I had someone spend half a day last week looking for an old (clay) waste pipe. We have the manhole end and want to connect up 10mm away, and haven't found it yet.
