I just set this one up in our pond.
http://www.sportsmansguide.com/product/index/moultrie-30-gallon-easy-lock-feeder?a=1163915We had the one above posted by ItalyBASS. We didn't like it because to mod the spreader to be directional it was difficult and the feed would get under the spreader paddle. The Easy lock one I have posted a link to had parts that can easily be replaced and the aluminum shield I put in place for directional feeding was a snap. Just cut heavy aluminum to 2.25" tall about 6"s long and placed it in as you installed the motor base.
If you look at the two bottom spreaders they are different.
Cheers Don.
P.S. now that I have had two I have two sets of legs. We could set it out much deeper and farther off shore.
