www.anglersyakshack.com. They're an internal bait tank for your yak and happen to be effective for more than 2 dozen pieces and it energy efficient. They are more expensive than other bait tanks but it is a whole different type of tank and is the cleanest setup available. Atleast contact mo about the product and check it out. I have one and would recommend it to everybody (and I will continue to).... Mo is pretty cool and does good work....
