ARROWHEAD WITH LASER
First Claim
1. An arrowhead comprising:
- a body, the body including an internal cavity;
a plurality of blades extending outwardly from the body;
a sharpened tip extending forwardly from the body, the tip having a center axis, and an aperture formed in the tip that extends outward along the center axis of the tip;
a battery housing extending rearwardly from the body, the battery housing including a rearwardly extending threaded portion, the threaded portion including a hole defined longitudinally therethrough, and the threaded portion being sectioned longitudinally into first and second halves with a slot defined between the first and second halves;
a battery disposed in the battery housing; and
a front laser diode disposed in the internal cavity of the body, the front laser diode arranged so that the laser beam emitted by the diode projects forward from the arrowhead through the aperture in the tip, the laser beam being coaxial with the center axis of the tip.

Abstract
An arrow, arrowhead and method of shooting an arrowhead are disclosed. In one example embodiment, a plurality of blades extend outwardly from the body of an arrowhead and a sharpened tip extends forwardly. A front laser diode is disposed in the arrowhead and is arranged so that a laser beam emitted by the diode projects forward from the arrowhead through an aperture in the tip and is coaxial with the tip'"'"'s center axis. In another example embodiment, the housing includes a rear facing light source to selectively light the nock. The method includes indexing the arrowhead to the vanes by tightening a set screw disposed in a portion of the arrowhead disposed in the arrow shaft.

16. A method of shooting an arrow, the arrow comprising an arrow head, a shaft and a plurality of vanes, the method comprising:
-
indexing the arrowhead to the plurality of vanes by tightening a set screw disposed in a portion of the arrowhead; disposing a magnet on a bow; engaging an arrow with the bow; drawing the arrow back until a forward facing laser beam in the arrowhead turns on in response to a hall effect sensor sensing the presence of the magnet; and turning off the forward facing laser beam when the hall effect sensor does not sense the presence of the magnet. - View Dependent Claims (17, 18, 19, 20)
