Abstract
The present invention relates to a bowfishing method, bowfishing system and laser bowfishing sight for targeting and illuminating an underwater target. The position of the target is compensated for the refraction of light in the practice of the method and sighting in of the system of the present invention. The laser bowfishing sight includes a rotational adjustment for compensating for the refraction of light.
Claims20
A method of targeting an arrow on an underwater target with a laser sight, comprising the steps of:
- providing a bow;
- providing the laser sight attached to the bow, wherein the laser sight further comprises:
- a laser;
- a switch for activating the laser;
- and
- an attachment device for releasably attaching the laser bowfishing sight to the bow;
- wherein the attachment device comprises a base portion and an adjustment portion attached at an attachment point;
- wherein the attachment device is configured to adjust the linear distance of the laser from the attachment point;
- and
- wherein the attachment device is configured to rotate the laser about the attachment point through a vertical plane;
- activating the laser with the switch to project a laser beam;
- illuminating a target located below a water surface with the laser beam, a path of the laser beam to the underwater target being non-linear due to refraction of the laser beam;
- adjusting the trajectory of the arrow by an offset angle to compensate for the refraction of the laser beam, the offset angle being the angle of refraction of light passing from air into water;
- and
- launching the arrow from the bow in a straight line at the illuminated, underwater target.

A bowfishing system, comprising:
- a bow;
- and
- a laser sight attached to the bow;
- wherein the laser sight comprises:
- a laser;
- a switch for activating the laser;
- a retrieval system attached to the bow that includes
- a spool,
- a housing,
- a line;
- and
- an attachment device for releasably attaching the laser bowfishing sight to the bow;
- and
- wherein the attachment device comprises a base portion having an opening, an extension portion and an adjustment portion including an attachment portion, the extension portion further including a shaft received through the opening in the base portion, the shaft releasably attached to the attachment portion to reposition the laser in one or more of an X, Y and Z direction.
11 more elements
A laser bowfishing sight, comprising:
- a laser;
- a switch for activating the laser to project a laser beam;
- and
- an attachment device for releasably attaching the laser to a bow, the attachment device comprising a base portion and an adjustment portion attached at an attachment point to the base portion for releasably attaching the laser bowfishing sight to a bow;
- wherein the attachment device is configured to adjust the linear distance of the laser from the attachment point;
- and
- wherein the attachment device is configured to rotate the projected laser beam about the attachment point through a vertical plane.
