I'm not sure if I'm doing this now. The lady seemed more interested in just borrowing or hiring the detector from me than she was in paying $20 (to cover fuel costs) for me to come out and find it for her.
I told her the detector is worth quite a lot of money so I would rather not loan it out but would be more than happy to drive the 35kms to come and find it for her. She basically replied with I'll get back to you :|
Will see what happens I guess.
