I have a cable detector I made years ago, its simple and works very well. I 've never had enough need / got the round tuit to make a capacitance type p assive object detector. Its not hard to do tho if you can do basic electron ics. 2 oscillating circuits, one with a search coil one without, multiply t o hear the frequency difference. The higher the frequency, the more sensiti ve.

So far I've just resorted to drilling holes on occasion. Sometimes 2mm is a ll you need.
