Oscillating flasher for deep water fishing

A flasher for attracting fish in deep water fishing comprising:

• an elongated, non-floatable planar body whose length to width ratio ranges from 3:1 to 5:1 having an upper surface and a lower surface, a flat center portion, a downstream portion integral with the center portion curved upwardly at an angle ranging from 15.degree. to 25.degree. relative to the center portion and an upstream portion integral with the center portion curving downwardly relative to the center portion at an angle ranging from 5.degree. to 15.degree.,
• means for securing a fishing line to the upstream end of the flasher body and for securing a bait and fish hook to the downstream end of the flasher body, and
• a substantially square opening in the upstream portion of the body having a width and length greater than half the width of the body, the opening having a flap substantially the same size as the size of the opening connected to the downstream side of the opening, the flaps extending upwardly relative to the upper surface of the body at an angle with respect to the flat center portion of the body of about 20.degree. to cause the flasher, when pulled through the water, to oscillate horizontally about its point connection to the fishing line.
