Finnboy: "Since nobody else has replied I’ll give my $0.02. Get a long track snowmobile like 137”. It provides extra flotation. Eskimo quick fish hub house are great. The insulated models have less condensation and use less fuel. Buy a small battery powered fan made to hang inside. Otter sleds with their hitch are the best. Any fish finder will work. Most of the portable models can be equipped with a summer or winter transducer. Hope this is helpful. Let me know if you have any questions."
This is great info, thank you!
