There is a guy on ebay who sells tubes similar in size to the carrot. He calls them minnow tubes. The 3" is about the diameter of a pencil. Just big enough to slip a 1/8 oz jighead into. They catch EVERYTHING !!! I've been using them for several years now.There's definitely a carrot mold in my future. A salty carrot should get deep better than the tube. Just the ticket for clear water and highly pressured fish.
