Kayak anglers looking to keep their preferred bait cool and calm in an insulated bucket should check out the Frabill "Shrimp Shak". The Shrimp Shak has a Whisper Drive aeration system with durable insulation to keep the water temperature even throughout. The 1423 Frabill aerator runs on two D batteries (not included), and The Shrimp Shak even includes a cling-on bait screen for easy access to shrimp.
