Thread: Engel live bait cooler?

All I use is the round Egloo water cooler like you see on the work trucks, with a Marine Metal Power Bubbles. This is the one I put most all the minnows in, and then transfer a few to my small bucket as I use them. It's worked for years, even guided with this set-up, it works for me, and a lot cheaper than the Engle. Several years ago the word was the round bait coolers were better for the minnows, because with the coolers with corners, the bait would bang up there heads...? I know I've seen the minnows with banged up heads before, but I don't think the minnows farmers use the round ones?
I do know that all coolers are getting way to high for my taste.
