Abstract
The ice fishing tipup includes a heated flotation member which can be a bowl-like member. A vertically extending tubular member is supported by the bowl-like member and a rotatable shaft is disposed therein. A fishing line spool is carried on the lower end of the shaft beneath the bowl-like member and is rotatable with the shaft to play out fishing line. A trip lever is carried at the upper end of the shaft above the bowl-like member and is rotatable with the shaft. Signal means are provided on the tubular member and are releasably engageable with the trip lever. The signal means serve to interrupt rotation of the trip lever to thereby set the depth of the fishing line, and is released with rotation of the shaft to indicate the playing out of fishing line. In the case of a floatable bowl-like member, combustible materials may be contained therein to generate heat upon ignition.
