Fuzzy, any of the cooler style bait buckets will work. I use the 12 volt one above. Just mounted it in the back of my boat under the lid. Put a on off switch inline. Ran the two lines into one. Fed the air line up to the front of my boat . All is hidden except for 12" of air line. Then I hook the one up from the bait bucket to it. I cant hear it at all. Only way I know it's working is bubbles in the bucket.
