The first question I ask people regarding a portable is – “Will you be towing it?”
If it’s the kind of portable you’re pulling out of the truck and dropping on the ice next to you, there’s a million options that will work well. At that point, durability and weight really have much less bearing on the overall decision, provided you can load it into the truck yourself. Of much greater concern then is warmth and layout/design. If those don’t concern you as much, and price is a driving factor, you’re probably going to be satisfied with most anything to be honest.
Most folks will answer that question as “Yes, but I hand-tow my sled quite a bit as well.” I think that’s the standard response whether true or not, but it’s an important answer. Be honest with yourself about how much you’ll really hand-tow.
If you are towing with either a snowmobile or ATV, Otter is really your best choice. For your loading concerns, I’d recommend an Otter Cabin with the new insulated fabric. It has less to do with brand as much as it has to do with how much money you’ll have sunk into a portable no matter which brand you go with. If you’re going to be investing that money and then taking it for rides across uneven ice, broken terrain, landing gravel and concrete, you’re going to need something that’s bombproof. I have alot of confidence in their sleds and materials based on what I’ve done to mine over the years, and I can’t say the same for what others I’ve owned or friends have purchased.
Ice fishing has become so specialized, it’ll really come down to thinking about the way you fish most often and tailoring a product to fit that method best. Good luck!
