You could use one of those fancy side-scan sonar depthfinders with the new underwater fish-eye orthographic readouts. Or you could go cut a switch of bamboo and do a little cane-pole fishing. If you choose the latter, a decent cane pole is as close as the nearest stand of bamboo. Everyday ordinary, backyard bamboo works just fine for panfish, bass, and small catfish. Make a cane pole our way, with the line anchored to the pole along its entire length, and you'll be able to land anything that doesn't pull you into the pond first. So there. Drop your line right beside that tree stump. Sit on a bucket. Doesn't that mud feel squishy between your toes? Hey, where's your bobber?
