Engel 13 qt. bait cooler. Have had mine for 2 years. Put up to 100 shiners (usually 60) in it on 95 degree summer days and they last for days. Put water in the cooler from where you are fishing when you get there. Put the bags of shiners in the water. Let the 2 water temps kind of even out then cut bags and let the shiners into the cooler. Dip out dead shiners when you see them. I used shiners yesterday. i caught crappie and no one else had bites. They weren't using shiners. Also caught bass. i generally catch a bunch of bass with shiners. not really trying to catch bass but they love shiners.
