I’ve went through a few one man shelters, and I’m pretty interested in the Otter version. One man shelters are very very nice in cold winters like we are experiencing. I would suggest a couple things; First off be sure that your shack has a zippered front. I have had 2 that didn’t, and once you get on a hot bite you typically would like to shove in, and get out for whatever reason. If it isn’t a zippered front you will always lose your seal to the ice everytime you get out of the house. Second off is if there is a way to connect the one man to your sled or atv via rigid towbar you will be very happy. Otherwise if you are looking go get away from the crowds you will be foot traffic only. Tends to limit you a bit vs. a shack that can be towed. I fastened most of my needed ice fishing gear to the sled itself. Scoop, small tackle box,small shovel… Pretty nice not having your gear broken and in a pile when you arrive to your destination. Lastly a dark colored house (Black, Dark Green, Purple) to catch some solar heat. Doesn’t take much in those little shacks. Oh a small 1lb propane tank and micro sized sunflower will heat you up in no time. I typically flip over and pull the flaps inside the shack so I can shovel in from the inside of the house. Less time outside is a good thing when it is freezing!! I’d be interested in taking a close look at the one man Otters!! If they are anything like the rest of the product line I’m sure it is very good quality!!
