Ice fish casting submarine having bait/lure carrying compartment

An ice fishing submarine for carrying an end portion of a fishing line radially away from an ice fishing hole comprising:

• i) a hull enclosing a propulsion system which includes a battery which powers an electric motor which turns a propeller;
• ii) a power switch to begin propulsion;
• and,
• iii) a tether having an unfixed end secured to the submarine and configured to interrupt power to the propulsion system when the tether becomes taut;
• and
• iv) a bait/lure compartment within the submarine for enclosing and carrying the end portion of the fishing line, said bait/lure compartment having an external door which automatically opens dumping the end portion of the fishing line into the water when a pin, attached to the unfixed end portion of the tether, is pulled when the tether becomes taut;
• so that when the submarine travels the distance of the length of the tether radially away from the ice hole, the tether then becomes taut and thereby automatically pulls the pin, opening the external door and switching power off to the propulsion system of the submarine, thereby eliminating the necessity of running control wires extending down through the ice hole to the submarine, and monitoring the travel of the submarine to turn off power at an appropriate time, as well as preventing any entanglement with the bait/lure which is enclosed within the submarine during launching and motion of the submarine away from the ice fishing hole.
