A turret display device is used for rapidly zeroing a riflescope. The turrets on an improved riflescope provide a turret position signal. A display of the turret display device comprises turret display cross hairs displayed relative to a target icon. When the turret display device receives a turret position signal, turret display cross hairs move to show the relative movement as indicated by the received turret position signal. When a distance is processed by the turret display device, the turret display cross hairs move to show an aiming point relative to a target icon based on the current zero of the riflescope. The user zeroes the riflescope to any distance by turning the turrets until the turret display cross hairs are centered for the desired distance. In some embodiments the turret display device is integrated into a hand held rangefinder, smart phone, or riflescope. A riflescope having turrets which each provide a turret position signal.

Before a person can use any weapon, such as a gun or a rifle, effectively, the sight must be aligned to the barrel through a zeroing process. An improved zero target is developed which is inexpensive and applicable to many different weapon sight scenarios. By making a universal zero target, users need only a single target eliminating the need for procuring and storing various targets. Additionally, the multi-sight target eliminates the need for field expedient zeroing solutions. The product saves both time and money and improves the results for weapon users.

The disclosed device, system and method allows for real-time axial alignment of a machine containing one or more axes that are driven by a motor. The axes can be rotational or linear. The system uses a plurality of lasers or equivalent optical emitters along with a detector camera in order to quantify alignment of the given axis with respect to a common plane, by means of providing the angular displacement of the axis from the axis normal to the plane. The system is insensitive to the relative angle of the detector plane. Furthermore, the device, system and method additionally provide self-correcting measures in the case that one or more of the lasers is out of alignment itself, so as to provide robustness to misalignment itself. In addition to the plurality of lasers or equivalent optical emitters and detector array, the device contains a feedback system to act upon error signals proportional to the degree of misalignment. The plurality of lasers and one or more cameras and feedback systems can be included in a system that includes hardware and software to process the data from the camera. The disclosed invention encompasses the device, system and methodology that are insensitive to disturbances of the system itself for both determining angular alignment of a given axis as well as the methodology for correcting for the given angular misalignment so that the axis is effectively aligned.

A bow sighting system for sighting in a bow includes a bow that has a sight. An arrow is selectively shot from the bow. A laser unit is selectively coupled to the arrow. The laser may emit a visible beam of laser light and the arrow is positioned in the bow. Thus, the visible beam of laser light is aligned with the sight thereby facilitating the bow to be sighted in.

The present invention relates to a sight system incorporating offset optical components. One embodiment is a sight system supporting multiple laser beams that are used simultaneously. As such, an assembly having two clamps is provided. Each clamp can hold a laser on opposite sides of a firearm barrel. The lasers can be diametrically opposed on the barrel wherein the lasers are in plane with a projectile axis. The lasers can project at the same time to bracket the location on the target of where the projectile hit impact. In another embodiment, the assembly, again with two clamps, is adapted for use with a bow, wherein the clamps support lasers that are in plane with the projectile axis. In another embodiment, the optical component is one or more cameras, wherein reticles can be displayed on a screen to bracket a target.

Exemplary testing systems and methods are provided including a system configured to test for thermal drift of a unit under test (UUT) under various temperature or environmental conditions and generating an output including visual or data on the thermal drift, if any. The methods involve attaching a UUT to a mounting device within a thermally controlled chamber, collimating light received from a UUT, recording the resulting images, and comparing the results at different temperatures to determine how much thermal drift has occurred. In addition, there are testing apparatuses capable of performing the tests.

A firearm sight adjustment and installation tool is described. The tool serves to facilitate and expedite the accurate adjustment and/or installation of sights on the slides of a firearm, whenever the sights allow this adjustment. The tool includes a plate, a plate with nuts, tightening screws, a spacer block, at least one adapter, a drift screw, an interchangeable pushing element and quick reference featured on one of the plates. With the tool and little expertise, an individual may manually adjust both the front and rear sights of a firearm to increase the accuracy of the firearm without additional tools.
