We rarely see fish on drop-offs because the closest “bottom” to the transducer is the drop-off, so the fish are not displayed. Sonar displays the echo strength of the target and the distance the target is from the transducer. The first example has the fish a farther distance from the transducer than the bottom so the fish echo is added to the “bottom“ echo and not seen. The “bottom” under the transducer is 25 ft, fish at 23 ft, and the drop off “bottom” is 20 ft. Now visualize what the sonar will show you. The picture is my rough drawing so it is not to scale; it is just to get you thinking.
If you can’t find fish near the bottom with sonar - you can’t catch them! I will show you one way to find hidden fish.
Fish close to the bottom are sometimes displayed as bumps. You have 2 ways to decide if a bump on the bottom is a fish. You can drop an underwater camera or use high definition color sonar. Fish return weaker echoes so they display a different color than the bottom depending on the setting of your colorline and sensitivity.

“I fish fish fish,” said Bruce Samson in a simplistic, matter-of-fact sort of way. His premise surely is not brain surgery, either, but after hearing the good doc explain further, you get the feeling he’s taking you places you have never been before.
Let’s backtrack momentarily, though, and profile the man his peers call Doc. He is actually Dr. Bruce Samson, M.D., a medical doctor who resides in Minnetrista, Minn., a western suburb of Minneapolis. He began practicing family medicine in 1976 and swung to urgent care and the emergency room in 1991.
Teaching kids to fish with roach rigs is not impossible.
The Roach Rig is a slip rig. This rig was developed for serious anglers to catch light biting fish. Most children don’t have experience, the feel, or the coordination to use this rig effectively. Basically this rig allows you to feel the fish, release the line to let the fish swim with the bait with no line tension.

You view your Lowrance waypoints on Google Earth. Google Earth has satellite images of Earth that you can zoom in and see lakes and rivers. This is another way to view where you placed your waypoints on a different map than on your Lowrance GPS map.
Some images can show weed lines and shallow rocks. By placing waypoints on Google Earth can mark fishing spots for future use.
