Stroll on Callum, rather you than me.
Have you tried using a pipe to your ear? Something like a metre of 22m copper pipe - clasp your hand around the end, and then press your ear against your hand. Check the most likely spots. Try using a pipe detector to trace the line of piping and check along the route.
Good luck with it - let us know how you get on.
