I also hand feed. My age, shoulder & elbow limit the amount & distance I can throw a 28 ounce can of feed. I found a dog ball launcher & ball for about $5. Duke's Dog Toy Ball Launcher, blue plastic, I had to use the magic fix all duct tape to cover the holes, shaped somewhat like a Jai Aalii cesta, holds about a quarter of the 28 oz. can.
Easy & stress free to throw. With little effort, I can get 40-50 feet. The part I like the most, it is easy to spread the pellets out over a greater area. Some fish appear to be more comfortable eating 40 feet from the bank others right at the bank is fine, still other groups hang out at the far left or right. The smaller fish don't have to get into the scrum for food. With the food spread out the turtles, TGC, & large TP get a bit less. All seems to work well.
