Here's the same tube rigged for trout fishing. Note the two fly rods in holders on the right, the fish finder (sonar) on the left. All gear fits into the two pockets on the sides. The net and additional items go behind the seat. In this model you sit high and dry with your wadered legs wet only below the knees.
Here my grandson in his tube. He has an ODC 420, another pointed nose model which is very similar to the SFC, only about half the price. Note the fish finder on the right of the picture, the sleeve that it fits in, and the rod holder on the left. He wears a blue inflatable PFD.
Here is his tube in action. In this photo he's landing a trout that he hooked while executing the deadly tubers troll with a fly.
Here's a side view of the SFC. Perfect line position for casting or trolling.
Here's a shot with the diver's fins I use. These are Mars Plana Avanti 3's (they're blue in the picture.)
Fish finders mount on tubes very easily, helping you keep track of structure, depth, and temperature. Here's a shot of one I use. It's mounted on a plastic pipe cap which fits into the cup holder on the tube. A PVC pipe with the transducer mounted on it is bungied to the side of the tube for easy raising and lowering.
The only drawback I have found with float tubes is that carp are quite spooky of them. Though you can work stealthily up on most freshwater gamefish, carp seem to be put down by the leg motion. A fly fisherman is also too low to the water to spot carp when sight fishing.
