American Hunter with a modified digital timer under a 55 gallon barrel on a tripod over a submerged island. Guessed wrong on the max water height and had submereged electronics once. Never had a jam. It has an internal funnel and is set to feed 3 times per day for 16 seconds (about 1 pound). Solar battery charger and a skirt around the barrel to prevent the "sling" effect. and a 10' PVC "ring" to hold the feed over both deep and shallow areas.
