Based on the hugely popular Engel Cooler/Drybox, the Engel Live Bait coolers add a 2-speed aerator pump that can run on batteries, 12 volts or 110 volts. Engel features best-in-class live bait wells that will keep your minnows and shrimp alive even while ice fishing or crappie fishing. Better than a bait bucket, these will not spill when knocked over and maintains internal temperature for longer.
