Sometimes called a Fox and Hound or a Tone Generator…Justin, have you ever played with one of these :

I bought one of these over 10+ years ago looking for a wire in the boat. I paid next to nothing for what I thought was a real piece of crap. I was within inches of heaving it into the ash can until I started to get the hang of using it. Nothing in the instructions about the finer points of using the tracker. It was an art, more than anything else but I got to where I could trace a wire, stashed in bundles, from one end of the boat to the other in one fell swoop, usually more often than not. It did the job for me.
Fast forward 10+ years and I'm sure they're vastly improved from what they were back then. Probably don't even have to be on your boat to trace the wire .

I don’t have one, but it is on my wish list!
