Oh I'm very serious.
Tends to find some false positives but it's great at finding plastic pipes up to about 1.5m deep
If the ground is churned up a lot can get a bit confused but better than not having a clue.
Doesn't work for everyone, but works for me.
Tracing wires, cables and metal pipes with trackers etc works for everyone, but plastic doesn't show up.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
