A device for producing a small (approx. 1 diameter) penetration through ice quickly. The device is a penetrator having a conical shape. The penetrator includes a ceramic cone having spiral grooves that house a high resistance wire. The wire supplies heat upon being energized. A high thermal dielectric and a metallic shroud are placed over the cone and wire to provide uniform heating to the surrounding area and to prevent short-circuiting of the device.
