Abstract: An ice fishing system comprising a variable stiffness jigging mechanism inside a housing. The jigging mechanism includes an oscillating arm having a flexible tube that supports and jigs the fishing line. The fishing line is draped over a flexible line guide. The flexibilities of the flexible tube and the line guide are chosen to suit the particular kind of fish to be caught. A heat exchanger in the housing has a slidable glass door that protects a burner from the wind as well as provides illumination inside the housing. The heat exchanger is spaced from the housing walls to provide adequate air circulation around it. A lid of the housing is strong enough for a fisherman to kneel on.
