FC:

I've found lots of 20'+, but as far as the depth finder goes, you may not need it. All the fish I've caught were around visible structure or lined up with landmarks. Once you find fish holding 7'-10' down over 7'-x' of water, you'll probably be posting better results than me. Once I get a better fishfinder, I'll be on the hunt for the hidden spots. When you find a couple spots, well trade up and double our catch! Honestly, I'd love to expand my lake selection...Jordan, Harris, etc. But with the price of gas, I'll just have to be a Raleigh Lakes puddle pirate for now.
