ABSTRACT:
An electrical heating device to prevent freezing of water within an ice fishing hole which includes a sleeve, an electrical resistance heater and a pair of electrical leads. The sleeve substantially forms a circle with an inner and an outer surface. The outer surface contacts the ice at the periphery of the ice fishing hole with sufficient outward pressure to suspend the heating device within the ice fishing hole. The electrical resistance heater is mounted to the inner surface of the sleeve and includes an electrical resistance heating element (or elements) enclosed within a waterproof jacket. The waterproof jacket forms a substantially circular base which is connected around the inner surface of the sleeve. The pair of electrical leads extend from the electrical resistance heater and connect the electrical resistance heater to a battery.
