Should be alright if your fishing on the ice or a portable. another 1/2 of ice on leech last weekend and would have been tought with out one but I always use mine in my wheel house
you might need one in your fish house it was pretty close last weekend for me. outside i found a spot where it was getting pretty close to needing one. im going to bring mine with but im not putting it on until i know i will need it. you should be ok but i would bring it with just in case
