I made my lead line from an old window weight.
A fishing pole and a bobber is a good tool. Use a small bobber and a large sinker. You can set your depth. If the bobber sinks you should float. You can find the shallow water as far away as you can cast. The keel can find all the shallow water right next to the boat.
