Well, you can survey in the node locations after you find 'em, with a compass (lensatic preferred) if you can sight some landmarks. A location technique for the OFF-capable units might include running a plumber's snake into the outlet pipe, to get the range from that outlet location. Any buried wires SHOULD have a 'warning' plastic marker tape over the buried conduit, and you can either follow that as you dig, or install it after you find your target.
