I was thinkning the same thing thought it lowered for towing announcer made it sound that way.
I am pretty sure it is all about staying warm, and keeping the hole in the ice from freezing back up. With the
hauler up in the air cold air streams in the hauler up and over the hole, with it sitting on the ice, sorta makes a seal. But I have only seen those crazy icefisherman on tv, it is nice that they have 2 holes tho, so you can fish with a buddy. But damn who wants to ice fish anyway?
