The mistake well maybe not mistake but i see alot of anglers getting out on the lake drilling there 2 or 3 holes and sitting there all day. Ice fishing is no different than open water, would you fish the same spot all day out of a boat if it was slow? I think not. Make sure you have lots of fuel for the auger and get out there and cut some ice. I like to drill in a zig zag pattern from shallow to deep and the laterally. Cover some ground and move to the fish. Once you get on the fish follow them as they move into the shallows in the evening by bouncing holes inward toward the shore as the sun drops. Ice fishing can be just as verastile but ya need a good auger. Good luck
