A system includes an accessory for a mobile computing device, the accessory including a body defining an interior configured to secure a mobile computing device, a communications module configured to receive an electronic command to eject a projectile, and a projectile launcher, coupled to the body, configured to eject a projectile in response to the command. The system also includes a projectile disposed in the projectile launcher.

A high impact strength lighted nock assembly for an arrow that is activated when the arrow is fired with a bowstring. The lighted nock assembly includes a nock molded from a high impact strength, transparent polymeric material containing at least 10% by weight reinforcing fibers. The nock includes a head configured to engage with the bowstring and a shank configured to couple with a rear end of the arrow. The shank includes a recess extending in a distal end of the shank toward the head. A light assembly including a light emitting device is located in the recess in the shank that is electrically coupled to a battery. A switch is electrically coupled to the light emitting device and the battery that is triggered when the arrow is tired to activate the light emitting device.

An arrow with a first body having a cylindrical member with a first outside diameter, a first outer surface, a first inner diameter, a first proximate end, and a first distal end, where the first proximate end is configured to accept an arrow head, a second body having a hollow cylindrical member with a second outside diameter, a second inner diameter, a second outer surface, a second inner surface, a second proximate end, and a second distal end, where the second distal end is configured to accept fletching, and a nock, and a connecting means to couple the first body to the second body, where the connecting means establishes a linear alignment of the first body to the second body along the device's longitudinal axis, and where the connecting means permits the first body to be removable in relation to the second body.

A tracking system for use with an arrow including a base unit defining an open central section; a holding magnet positioned within the open central section; and a sending unit that includes an electronic circuit; a main body section affixed to an electronic circuit; projections extending from the main body section into the open central section and at least partially surrounding the holding magnet; and a projection extending from the main body section and ending in a point; where the electronic circuit includes a battery and is constructed to emit a tracking signal when activated and the electronic circuit includes a magnet switch element such that the electronic circuit is maintained in a deactivated state as a result of the magnetic field established by the holding magnet.

In some embodiments, an arrow comprises a shaft comprising a tubular wall comprising a cavity and a nock comprising a notch arranged to engage a bowstring. An intake inlet is in fluid communication with the cavity and an exhaust outlet is in fluid communication with the cavity.

An arrow includes an arrowhead, a shaft, a nock, and an internal cavity. The internal cavity includes a camera.

An arrow with a first body having a cylindrical member with a first outside diameter, a first outer surface, a first inner diameter, a first proximate end, and a first distal end, where the first proximate end is configured to accept an arrowhead, a second body having a hollow cylindrical member, where the second distal end is configured to accept fletching, and a nock, and a connecting means to couple the first body to the second body, wherein the arrowhead is a hollow coring arrowhead configured to cut a volume of material through a target, and where mass and fluid passes through the coring arrowhead to the first body, and where one or more rods are positioned within the second body, where the rods are exposed to the target after the first body detaches from the second body.

A cylindrical carbon fiber arrow shaft formed with an exterior surface having single or multiple outside diameters and formed with an axial bore having multiple interior diameters. In a preferred embodiment, the exterior surface of the arrow shaft has an increased external diameter at the nock end and tapers to a smaller external diameter at the tip end. The axial bore has an internal diameter at the nock end corresponding to standard arrows having external diameters of 0.295 inches and tapers to a smaller internal diameter at the tip end. Modifying the length, diameter, and wall thickness of the arrow shaft varies the stiffness of the arrow shaft along the length and shifts the center of gravity along the length of the arrow shaft and as well. Utilizing standard internal diameters, nock and tips may be attached without spacers or inserts, thereby decreasing weight of the arrow significantly.

An improved method, device, and system for hunting and selectively placing a scented hunting aid is provided. A hand-thrown dart may have a tip and a flight attached opposite thereto. The flight may carry a scented fluid or scented material thereon. The flight is configured to be positioned above the ground after the dart has been thrown by hunter from a tree stand. The dart enables the hunter to selectively throw the dart such that its placement is upwind from a desired game animal such as a buck deer that the hunter desires to attract. Some implementations utilize peelable covers to release the scented material, while other embodiments utilize a porous or sponge-like flight that is saturated with a scented fluid.

An enhanced slide and a circumferential stop assembly for use with a bowfishing arrow may include matching shapes for engaging one another in use. The engagement of such matching shapes offers many improvements over conventional slide and stop assemblies, including an even circumferential distribution of impact between the slide and the stop as well as inhibiting relative longitudinal or rotational movement between the slide and stop assemblies. The stop assembly may further include a nock adapter for engaging a nock, thereby serving as a dual purpose adapter. For ease of use and installation, the stop assembly may be an outsert, meaning that it is adapted to fit snugly over an arrow shaft.
