I know that several of the Utah Ice Shanty crew are using battery operated aerators to keep their holes ice free while fishing with out shelters and for jaw jacker/tip-up holes. One of the more popular units is the Marine Metal Bubble Box (Amazon Prime $7.96 + tax). Looking the Bubble Box up on Amazon, I also found the Hush Bubble (Amazon Prime $15.98 +tax). At double the price for the Hush Bubble, is it worth the cost increase? I'll probably order a couple of units tomorrow afternoon and have then for my next perch search on Tuesday or Wednesday. What do y'all think; anybody here used the more expensive Hush Bubble?
