As David said above some use a deer feeder to feed fish. I have been using one for 5 years now! I have mine in about 4 foot of water but it will chunk food out into the 8 foot area.
Pros -
1. Not near as pricey
2. Works real well I set feeding twice a day.
3. Throws food in about a 10 to 15 foot circle.
4. I have mine out far enough where is can throw food in a 360 which give the smaller fish near the shallow a better chance at getting some food as well.
Cons
1. Not as good looking
2. Harder to fill up either need to get in a boat to do it or I have used waiters and a step ladder to fill up course mine is in a relatively flat area so I can use a step ladder.
4. Must be in a relatively level /flat area.
5. If the coons find it you better get a varmint cage put on it or they will empty it in a couple days!!
