I thought of a telephone tone generator but I need something that I can read from a max depth of 18". In order for a "TTG" to work the probe (receiver) signals when the wire, or coating is actually touched. It would be hard to find a single set of wires in a bundle of 50 if it went off at 6" away!
I found one that runs about $270 that looks like it will do what I need and much more.
Everybody seems to think that I need something outragous when I only need something very simple!
And..I'm not the one who buries the lines, just the one that my customers ask to fix them!! lol (When they're living in 2-7 million dollar houses, you try to accomidate them, if you get my drift!!) Hell if I can make $60/hr for poking around fixing some landscape lighting, who's to say no? It's not like I'm trying to hook-up a whole house generating system, which is something I wouldn't try anyway! lol
